Is the relationship between volume and pressure direct or indirect? Explain your
answer

Answers

Answer 1

Answer:

Boyle's Law is a relationship between pressure and volume. In this relationship, pressure and volume have an inverse relationship when temperature is held constant. If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure.

If a gas occupies 22.4 L at 0.265 atm, then what will the pressure be in atmospheres if the gas occupies 35.52 L? Assume all other
variables are held constant
A)0.167 atm
B)0.437 atm
C)0.886 atm
D)149 atm

Answers

Answer:

The new pressure is 0.167 atm

The correct answer is option A

Explanation:

Step 1: Data given

Volume of the gas = 22.4 L

Pressure of the gas = 0.265 atm

The volume increases to 35.52 L

Step 2: Calculate the new pressure

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 0.265 atm

⇒with V1 = the initial volume = 22.4 L

⇒with P2 = the new pressure = TO BE DETERMINED

⇒with V2 = the increased volume = 35.52 L

0.265 atm * 22.4 L = P2 * 35.52 L

P2 = (0.265 atm * 22.4 L) / 35.52 L

P2 = 0.167 atm

The new pressure is 0.167 atm

The correct answer is option A

An exothermic reaction releases 13,450J of heat. How many calories of energy are released? A) 5 56,274 calories B)1,244 caloriesC) 134,500 caloriesD) 3,215 calories

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.

Answers

Answer:

1. The Nummber of electrons present in the outermost shell is called Valence electrons.

2. Thomson model:

Thomson model of atom is the model which states that electrons are embedded in a positively charged solid material which is spherical in shape.

Rutherford model

Rutherford model of atom is the model which explains that there is a nucleus in the center of the atom and electrons are located around the nucleus.

3. Relative atomic mass. Atoms have very little mass , so they're difficult to measure accurately. Instead, chemists use a scale. On this scale the mass of a 12C atom is exactly 12.

4. Difference between Alpha, Beta and Gamma radioactive decay:

Alpha decay forms new element with two fewer protons and two fewer neutrons;

Beta decay forms new element with one more proton and one fewer neutron.

Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.

Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last. However, alpha particles make the most damage even if it has the lowest penetration power among the three.

5. This species has a 2− charge on it, so it is an anion. Anions are named using the stem of the element name with the suffix -ide added. This is the oxide anion.

2) M=0.45

3) 22.5 mL

4) 6.25 mL

Explanation:

1)

550 mL= 0.55 L

M= mol solute/ L solution

mol solute= M * L solution

mol solute= (2.1 M * 0.55 L )        M=1.15 mol solute

2)

155 mL = 0.155 L

80 g  -> 1 mol NH4NO3

5.61 g -> x

x= (5.61 g * 1 mol NH4NO3)/80 g       x= 0.07 mol NH4NO3

M=(0.07 mol NH4NO3)/0.155 L         M=0.45

3) M1V1=M2V2

V1= M2V2/M1

V1= (0.500 M * 0.225 L)/5.00 M             V1=0.0225 L =22.5 mL

a. What is the mass in grams of 4.2 mols of FeO2?​

Answers

4.2 Mols FeO2 * 71.844g/1mol = 301.74g FeO2

According to mole concept, there are 368.928 g  mass in 4.2 moles of FeO₂.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

Number of moles=mass/molar mass

Thus, mass=4.2×87.84=368.928 g.

Thus, there are 368.928 g  mass in 4.2 moles of FeO₂.

What is the molariity of a 50.0 mL aqueous solution containing 10.0 grams of hydrogen peroxide, H2O2?

Answers

Answer:

6 mol/L

Explanation:

You should know or have the equation to solve for Molarity which is;

M = n/v          (M: Molarity) (n: moles of solute) (v: Liters of solute)

You can start off differently but I would start by converting the mL to L. This is your "v" value.

50.0 mL/ 1000 mL = 0.05 L

Now, you have to convert grams to moles in order to solve for molarity (M).

1.) On the periodic table find the molecular weights of H and O.

H= 1.01 g/mol         O= 16.00 g/mol

2.) Multiply them and then add them together to have their combined molecular weights. (You have to multiply by 2 because of their equation; H2O2).

2(1.01) + 2(16.00)= 34.02 g/mol

3.) Now, you're going to use the "picket fence method" or whichever your teacher taught you to convert from grams to moles. This will be your "n" value. (I cannot show it on here without it looking weird, so my sincere apologies.)

10.0 g/ 34.02 g = 0.2939 mol

4.)You are now going to plug in your answers into the equation for Molarity.

M= 0.2939 mol / 0.05 L = 5.878 mol/L

5.) I am sure your professor might be a stickler so for sig figs sake when you multiply or divide use the smallest amount of sig figs you see which is 1. Round 5.878 to 6 mol/L

Sorry this explanation is very long let me know if you need a better more written out explanation.

(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.

Which formula represents an alkane?
1.
C2H2
2.
C2H4
3.
C3H4
4.
С3Н8

Answers

Answer: Option 4) is correct.

Explanation: It is correct because alkanes have a general formula CnH2n+2. So, all we need to do is substitute and find out how many hydrogens are needed to make the formula an alkane. I am not really good at explaining. I am sorry If I confused you.

Alkanes are the organic compound which has general formula [tex]C_{n}H_{2n +2}[/tex] which satisfies the formula [tex]C_{3}H_{8}[/tex]. Hence [tex]C_{3}H_{8}[/tex] represents an alkane.

Alkane

Alkanes are simplest saturated hydrocarbon. Alkanes are also known as paraffins wax. Alkanes which contains only carbon and hydrogen atoms.

General Formula of Alkane

The general formula of alkane is [tex]C_{n} H_{2n + 2}[/tex] where n = 1, 2, 3, 4.......  

Consider Option 1, [tex]C_{2}H_{2}[/tex] here n = 2 now put the value of n in above formula, we get: [tex]C_{2} H_{2 \times 2 + 2}[/tex] = [tex]C_{2} H_{4 + 2}[/tex] = [tex]C_{2} H_{6}[/tex] , so option 1 does not satisfies the above formula. Hence it is incorrect. Consider Option 2, [tex]C_{2} H_{4}[/tex] here n = 2 now put the value of n in above formula, we get: [tex]C_{2} H_{2 \times 2 + 2} = C_{2} H_{4 + 2} = C_{2} H_{6}[/tex], so option 2 does not satisfies the above formula. Hence it is incorrect. Consider Option 3, [tex]C_{3} H_{4}[/tex] here n = 3 now put the value of n in above formula, we get: [tex]C_{3} H_{2 \times 3 + 2} = C_{3} H_{6 + 2} = C_{3} H_{8}[/tex], so option 3 does not satisfies the above formula. Hence it is incorrect. Consider Option 4, [tex]C_{3} H_{8}[/tex] here n = 3 now put the value of n in above formula, we get: [tex]C_{3} H_{2 \times 3 + 2} = C_{3} H_{6 + 2} = C_{3} H_{8}[/tex], so option 4 satisfies the above formula. Hence it is correct.

Thus, from the above conclusion we can see that option 4 [tex]C_{3}H_{8}[/tex] represents an alkane.

Autumn Friday nights, the time where the unlikely pair of music and sportsmanship collide, and amid it all, drum majors stand tall, leading the mighty Raider Brigade by both conducting and example. I have always dreamed to be in their position, and now, I am thankful to have the chance to make this dream a reality. I view the position of drum major as one of both honor and responsibility, and there are a multitude of reasons I would love to lead in this position for the Raider Brigade. When I was much younger, I used to beg my dad to take me to band concerts, so I could pretend to direct along with the band conductor, and by second grade, I knew that I wanted to play flute. Within this year, I became sure in my dream to become a band director. To me, becoming a drum major would mean that I would get to live my dreams out years in advance, and although my young age may be seen as a disadvantage, it is, in reality, anything but. As an upcoming sophomore, I still vividly remember the transition issues and growing pains that accompany going from middle school to highschool, and because of this, I can give current, relevant advice. Through the 2019-2020 school year I confided in my section leader, who guided me and gave me advice when necessary, and without her, it would have been impossible to make it through the year. If I were to make drum major, I want to form those relationships with upcoming freshmen, to make sure they know they have a place before school begins, in the large, loving Raider Brigade. The Raider Brigade in itself is a beautiful family that has united for the common goals of making music and performing a beautiful show for the crowd, and as a potential drum major, my only aspiration is to make this organization even better. I see true talent in every member, and the only way to build on this is to ignite the passion of showmanship in each individual. This begins with the drum major. All leadership teaches by example, so if the leader is passionate, the band will be passionate. The raider brigade is hard work, but as drum major I intend to make everyone whistle while they work. This will make the beautiful Raider Brigade reach its full, spectacular potential.Overall, I want to be a drum major to accomplish my dreams, make connections with both the freshmen and every other member, and to make this wonderful band reach its full, amazing potential. Finally, I would like to thank you for this opportunity and your consideration, and I wish only the best for this band, which is why I am truly trying out. briefly describe the ending of the book One Of Us Is Lying a large triangular piece of canvas is being used to shade a playground.
