Use the term DNA in a sentence
about proteins.

Answers

Answer 1
Deoxyribonucleic acid, or DNA is a self replicating molecule found in the cells most living things; it’s wound around proteins called histones. When the cell wants to make a protein, instructions are copied from the DNA molecule strand and then transcribed to a new molecule, called RNA.

Sorry, that’s 2 sentences, but hopefully that’s helps you out.
Answer 2

The organic materials which are present in all organisms in the form of DNA or RNA are called nucleic acids. It is the basic genetic material of our body.

What is DNA?

The group of molecules which are responsible for carrying and transmitting the hereditary characters or the genetic information from parents to the offsprings is known as Deoxy-ribonucleic acid or DNA.

The DNA is a polynucleotide molecule, the polypeptide chains are further folded in secondary, tertiary and quaternary structures to form different proteins. Every organism contains many genes in its DNA, different types of proteins can be formed.

Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.84 × 10^24 C. 4.61 × 10^23 D. 7.87 × 10^23

Answers

Answer:

B

Explanation:

first find the no. Of moles of H2SO4

=  75/98.1

= 0.7645

Next step

In on mole of H2SO4 the no.of oxygen atom is 4.

1 H2SO4 : 4 O

0.7645  : x                     x= 0.7645x4= 3.0581

next multiply avogadros constant

3.0581 x 6.022× 10^23 =1.84x10^24

Mass present in 1 gram of mole substance is called molar mass. Molar mass is calculated by: dividing the mass of the compound in grams by the number of moles present in the substances.

The correct answer is:

option B. 1.84 × 10²⁴

Given,

The mass of sulfuric acid =75.0 g

The molar mass of sulfuric acid = 98.1 g/mol

1.The moles of sulfuric acid can be calculated by

M = m ÷ n

where M is molar mass, m is mass and n moles.

moles of sulfuric acid = mass ÷ molar mass

= 75 g ÷ 98.1 g/mol  

=0.7645 moles

Hence moles of sulfuric acid present is 0.7645 moles.

2. 1 mole of sulfuric acid = 4 oxygen atoms.

Then, 0.7645 moles of sulfuric will contain: 0.7645 × 4 = 3.0581 atoms of oxygen

3. Oxygen atoms present in 75.0 g of H₂SO₄ will be calculated by multiplying it with Avogadro's constant:

= 3.0581 x 6.022× 10²³

= 1.84x10²⁴

Therefore, 1.84 × 10²⁴ oxygen atoms will be found in 75.0 g of H₂SO₄.

Answers

Answer:

What that means is that when pressure and number of moles are kept constant, increasing the temperature will result in an increase in volume. Likewise, a decrease in temperature will result in a decrease in volume. In your case, the volume of the gas decreased by a factor of about 3, from "140.0 mL" to "50.0 mL".

A chemistry student mixes 25 milliliters of 3.0 M hydrochloric acid (HCl) with excess sodium hydroxide. The chemicals react according to this chemical equation:

HCl + NaOH → NaCl + H2O.

If the volume of the resulting solution is 68 milliliters, what is the concentration of sodium chloride?

Answers

Answer:

1.1 mol/liter

Explanation:

You would use the M1V1 = M2V2 equation to solve this.

We know M1 is 3.0 M, V1 is 25 milliliters, and V2 is 68 milliliters. We need to find M2.

To find M2, first plug in what you know.

(3.0 M)(25 mL) = M2(68 mL)

Then, divide everything by 68 mL to get M2 by itself

Your answer should be a quite large decimal but I rounded it to 1.1 mol/liter.

Answer:

The concentration of sodium chloride is 1.1 moles/liter.

what is the mass of 7.525 x10^24 particles of sulfur difluoride SF2?

Answers

Answer:

Mass will be equal to 874.56 gram

Explanation:

Molar mass of sulfur = 32 u

Molar mass of Florine = 19 u

Therefore molar mass of [tex]SF_2[/tex] [tex]=32+2\times 19=70u[/tex]

So mass of [tex]6.023\times 10^{23}[/tex] particle is 70 gram

Therefore mass of 1 particle

[tex]=\frac{70}{6.023\times 10^{23}}=11.62\times 10^{-23}g[/tex]

Therefore mass of [tex]7.525\times 10^{24}[/tex] particle is

Cuando se queman combustibles que tienen algún compuesto de azufre se produce dióxido de azufre (SO2), un gas irritante que puede provocar lluvia ácida. En el análisis del aire de una ciudad se ha encontrado una concentración de SO2 de 14 mg/m^3 ¿Qué cantidad de SO2 habrá en 1 L de aire?

Answers

Answer:

See answer below

Explanation:

I have to answer this question in english because is the rule here. I hope you can understand this.

Now, in order to answer this, is really easy. We already have the quantity of SO₂ in the air of a city. This concentration is 14 mg/m³, so we want to know the quantity in 1 L. This quantity can be expressed in mass.

If concentration according to the units is: mg/m³ This means that we have units of mass and volume. So, in order to know the quantity of SO₂ in mass, we need to convert the units of volume m³ to liter.

1 m³ is covered in 1000 L, therefore:

14 mg/m³ * 1 m³/1000 L = 0.014 mg/L

Then, the mass will be:

m = 0.014 mg/L * 1 L

m = 0.014 mg of SO₂

This is the quantity of SO₂ in 1 L.

How are renewable fuels different from fossil fuels

Answers

Answer:

Renewable energy

Explanation:

on the other hand, typically emits less CO2 than fossil fuels. In fact, renewables like solar and wind power—apart from construction and maintenance—don't emit any CO2 at all. With renewable energy, you can breathe easier, stay cooler, and create a more comfortable world for generations to come.

Answer:

renewable energy comes from natural resources that can be replenished or replaced during an average human lifetime ; eg, Hydro, solar, wind etc.

fossil fuels can take thousands or even millions of years to naturally replenish; eg, natural gas, coal, oil.

An example of a double replacement chemical reaction takes place in batteries. In an alkaline battery, Manganese oxide reacts with water to form a different manganese oxide and hydroxide. Which is the correct balanced equation for this?

Answers

Answer:

2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation.

When manganese oxide reacts with water to form a different manganese oxide and hydroxide, the correct balanced equation for this is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

What do you mean by balanced chemical equation ?

The term balance chemical equation is define as the equation which satisfy the law of conservation of mass, i.e., “Total mass of the products is equal to the total mass of all the reactants”.

If a chemical equation is not balanced, it will break the law of conservation of mass. It will indicate that either mass is created or destroyed, which is impossible.

Balanced chemical equations have the equal number and type of each atom on both sides of the equation.  

Thus, When manganese oxide reacts with water to produce a different manganese oxide and hydroxide, the correct balanced equation for this reaction is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.
