the combustion of 0.1240 kg of propane in the presence of excess oxygen produces 0.3110kg of carbon dioxide what is the limittinf reacrant?

Answers

Answer 1

Answer:

Propane

Explanation:

From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.

Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.

Answer 2

Answer:

The limiting reactant is propane, C₃H₈ and the percentage yield is 83.77%

Explanation:

Mass of propane = 0.1240 kg = 124 g

Mass of carbon dioxide = 0.3110 kg = 311 g

Molar mass of propane = 44.1 g/mol

Molar mass of carbon dioxide = 44.01 g/mol

Number of moles of propane = 124/44.1 = 2.812 moles

Number of moles of carbon dioxide = 311/44.01 = 7.067 moles

Equation for the reaction

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Hence 1 mole of propane ideally yields 3 moles of CO₂

Hence, 2.812 moles of propane will yield 3×2.812 moles = 8.44 moles of CO₂

Since, oxygen is in excess, therefore, the limiting reactant = Propane, C₃H₈

The percentage yield = 7.067/8.44× 100 = 83.77%.

Answer:

Without dark matter galaxies would loose an extreme amount of gas required to create stars.

Without dark matter the universe wont have as many galaxies clumped together forming larger versions of those galaxies. This would cause a change in the structure of the "skeleton" of the web.

(Hope this can help, I didn't do exactly as it is said to because that is your job)

Explanation:

Forbes gives somewhat of an explanation if you are curious.

(Ethan Siegal, "The Universe Would Be Very Different Without Dark Matter", Forbes)

Dark matter makes up most of matter in the universe and is found by a quarter of the total composition of the space. After the event of the big bang, the universe expanded and dark matter grew.

Dark matter accounts for about 85% of the matter in the universe. Its presence can be felt in the gravitational effects. Dark matter doesn't interact with the electromagnetic field. After the big bang event, the dark matter still can be found in larger galaxies and contest about 26% of mass-energy and 69% of dark energy. If there had been no dark matter there would be no structure of the cosmic web of galaxies. That is there would be no connection between the galaxies and would remain in isolated fragments.

Thus dark matter is a link within and with the comic web.

A gas occupies a volume of 2.45 L at a pressure of 1.03 atm. What volume will the
gas occupy if the pressure changes to 0.980 atm and the temperature remains
unchanged? Show your work in the space below. *​

Answers

Answer:

2.58 L

Explanation:

Please see the step-by-step solution in the picture attached below.

Hope this answer can help you. Have a nice day!

At constant temperature, if the pressure of the gas decreases to the given value, the volume increases to 2.58L.

What is Boyle's law?

Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Given the data in the question

Initial volume V₁ = 2.45LInitial pressure P₁ = 1.03atmFinal pressure P₂ = 0.980 atmFinal volume V₂ = ?

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = ( 1.03atm × 2.45L ) / 0.980atm

V₂ = 2.5235Latm / 0.980atm

V₂ = 2.58L

Therefore, at constant temperature, if the pressure of the gas decreases to the given value, the volume increases to 2.58L.

Answers

Answer:

The correct option is;

D) 3,215 calories

Explanation:

Here we are required to convert 13,450 J to calories

1 calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C

Therefore, 1 calorie = 4.184 Joules

Hence, 1 Joule = 1/4.184 calorie for which we have;

13,450 J = 13,450 × 1/4.184 calories = 13,450/4.184 calorie

13,450 J = 3,214.63 calories

Rounding up to the nearest  whole number, we have;

13,450 J ≈ 3,215 calories.

Explanation:

1. Trends in atomic size

Atomic size tends to decrease from left to right across the Periodic Table.

You are adding one electron at a time. the electrons repel each other, so the size should increase.

You are also adding a proton to the nucleus. The additional attraction should pull the electrons closer to the nucleus.

The nuclear pull wins, so the atoms get smaller from left to right

Atomic size increases from top to bottom of a Group.

You are adding electrons to an extra shell, so the size should increase.

You are also adding protons to the nucleus, so the size should decrease.

The size of the outer shell wins, so the atomic size increases going down a Group.

2. Lewis structures

(a) Ammonium ion

N is the central atom. The N atom has the positive charge.

(b) Sulfur trioxide

S is the central atom, with a double bond to each of the three O atoms.

If a buffer has an initial pH of 6.34 and the acid has a Ka of 3.46 × 10-4, what is the ratio of conjugate base to weak acid in the buffer system?

Answers

Answer: The ratio of conjugate base to weak acid in the buffer system is 758 : 1

Explanation:

The dissociation constant for  acid = [tex]K_a=3.46\times 10^{-4}[/tex]

pH = 6.34

First we have to calculate the value of [tex]pK_a[/tex].

The expression used for the calculation of [tex]pK_a[/tex] is,

[tex]pK_a=-\log (K_a)[/tex]

Now put the value of [tex]K_a[/tex] in this expression, we get:

[tex]pK_a=-\log (3.46\times 10^{-4})[/tex]

[tex]pK_a=3.46[/tex]

Now we have to calculate the ratio of conjugate base to weak acid in the buffer system

Using Henderson Hesselbach equation :

[tex]pH=pK_a+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

Now put all the given values in this expression, we get:

[tex]6.34=3.46+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

[tex]\frac{[\text {conjugate base}]}{[Acid]}=758[/tex]

Therefore, the ratio of conjugate base to weak acid in the buffer system is 758: 1

What is a dehydration reaction?

A reaction where two smaller molecules are combined in a chemical manner by the removal of an element from each of these molecules is called a dehydration reaction. Organic compounds are classified on the basis of structure. They are classified as aliphatic and aromatic compounds. Different kinds of chemical reactions are involved in the formation of new compounds when there is a change in bonding between the atoms.

There are some chemical reactions that form a molecule and some only show a displacement or substitution of atoms. There are synthesis or combination reactions that involve a combination of two substances to form one molecule.

On the other hand, there are decomposition reactions in which one substance decomposes to form more than one substance. There are displacement reactions which can be single or double displacement. They involve the displacement of one or more components of compounds among each other. Addition, substitution, rearrangement, elimination, and oxidation-reduction reactions are some of the common organic reactions.

Therefore, the correct option is A.

Remember, always use the absolute (Kelvin) temperature when working with gas equations.

The temperature conversions are

Explain the different principles that allow roller coasters to rip and roar around the tracks. In your response, include how energy is transferred back and forth between kinetic and potential.

Answers

Answer:

In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.

This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy

Explanation:

This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.

Explanation:

The following data were obtained from the question:

Mole of K2SO4 = 0.450 mole

Volume of water = 195.0 mL = 195/1000 = 0.195L

Molarity =...?

Molarity is defined as the mole of solute per unit litre of the solution. This can be expressed as:

Molarity = mole /Volume

With the above formula we can calculate the molarity of the K2SO4 solution as follow:

Molarity = mole /Volume

Molarity = 0.450/0.195

Molarity = 2.31M

When Kids Had Adult JobsImagine dragging yourself out of bed on a cold, dark morning before the sun has even risen. You dress quickly because youre running late. But instead of a day filled with schoolwork, soccer practice, and a few chores around the house, you head over to the towns mill where you will spend the next 10 to 12 hours. Thats what life was like for about 18 percent of American children ages 10 to 15 in the early twentieth century. Instead of going to school, they went to work.Before the Industrial RevolutionFrom the early days of America until the late 1930s, there were few laws protecting children from work. In colonial times, children often worked alongside their parents. Girls worked with their mothers cooking, sewing, gardening, and milking cows. Boys worked on their fathers farms or in their shops. Boys from the ages of 10 to 14 often became apprentices. They worked under the care and direction of master craftsmen. In both farming and apprenticeships, children learned the skills of a job from beginning to end. Those in apprenticeships not only learned a trade from their masters, they were also taught basic arithmetic and how to read and write. Plus, they were given a place to live and a wage.From Farms to FactoriesBy the time of the Civil War in the 1860s, however, the apprenticeship system had fallen by the wayside. The country was becoming more industrialized. Children worked to help support their families. Children were often hired to work in factories because factory owners found children easy to manage. They could be paid less than adults and were less likely to go on strike. An added benefit was their small size: children could easily move in tight spaces around machinery.Factory workers, including children, generally learned one repetitive job. This made training fast and easy. Despite their age, children often worked in hazardous conditions. They worked in cotton mills in New England and in the South. The windows of the mills were kept shut to keep the cotton moist and warm so it wouldnt break. Child workers would be covered in cotton lint that would fill their lungs. Towns grew around the mills. Families lived in houses owned by the mills. The mills provided a school. But the children usually didnt have time to attend. A study done in the early twentieth century revealed that half the children under age 14 could not read or write.In the early 1900s, children also worked in glass factories, canneries, cranberry bogs, and sugar beet fields. They went to work in the mines in Pennsylvania or West Virginia as a breaker boy. Breaker boys sat crouched over a coal chute. Their job was to pick out pieces of slate and rock as the coal rushed past them. The air was thick with coal dust, and many of the boys suffered from respiratory illnesses because of it. They earned 60 cents for a 10-hour shift of backbreaking work.Champions for Change Fortunately, some concerned citizens decided to stand up against child labor and to address the problems it created. In 1904, a group of reformers founded the National Child Labor Committee (NCLC) to abolish child labor. This committee hired investigators to gather evidence for their cause. One person they hired was Lewis Wickes Hine. Hine was a former teacher and photographer. He took pictures of children wherever they worked.From 1908 to 1912, Hine snapped pictures of children at work. He would hide his camera and trick factory bosses into letting him get inside. Hine wrote notes on a pad hidden inside his pocket. He wanted to accurately describe what he saw without being caught. His photographs showed children working in coal mines, sweatshops, and mills and on farms. When many of Hines photographs were published, the public was shocked. People were finally motivated to address the issue of child labor.Soon many states passed laws protecting children in the workplace. But despite these laws, children still worked hard. The NCLC pushed for a federal law for child workers. In 1916 and 1918, laws were passed. But those laws were overturned by the Supreme Court as being unconstitutional. In 1924, Congress passed an amendment to the Constitution. But not enough states ratified it, so it didnt become law. In 1938, the Fair Labor Standards Act was passed. It set a national minimum wage and maximum hours to be worked in a day. More important, it set limitations on child labor.Today, children are protected by child labor laws. The federal government has set the minimum working age at 14 for jobs other than babysitting or delivering newspapers. In some states the minimum working age may be higher. Childrens lives are much easier today than they were more than a century ago.
