Answer:

Mass = 110.88 g

Explanation:

Given data:

Mass of CO₂ = ?

Number of moles of CO₂ = 2.52 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of CO₂ = 44 g/mol

by putting values,

Mass = 2.52 mol × 44 g/mol

Mass = 110.88 g

Rainbow [258]

Answer:

4.86 moles of HCl

Explanation:

1. First write the balanced chemical equations involved in the process:

$CH_{4}+_4Cl_{2}=CCl_{4}+_4HCl$

$CCl_{4}+_2HF=CCl_{2}+F_{2}+_2HCl$

2. Calculate what amount of $CCl_{4}$ is formed in the first reaction.

$3.00molesCH_{4}*\frac{1molCCl_{4}}{1molCH_{4}}=3.00molesCCl_{4}$

As the yield of each reaction is 90.0%, the amount of $CCl_{4}$ produced is the following:

$3.00molesCCl_{4}*0.90=2.7molesCCl_{4}$

3. Calculate the amount of HCl produced.

$2.7molesCCl_{4}*\frac{2molHCl}{1molCCl_{4}}=5.4molesHCl$

The total amount of HCl produced with a 90.0% yield is:

$5.4molesHCl*0.90=4.86molesHCl$

A typical hydrogen peroxide solution from a drug store is labeled as 3.0% hydrogen peroxide. What is the other 97% of this compo

GarryVolchara [31]

Answer: Water

Explanation:

Chemically speaking, a solution has two components: solute and solvent.

The solute is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and its proportion in the resulting solution is usually less than the solvent.

The solvent is the substance used to dissolve the solute, and generally its proportion in the resulting solution is greater. Being the most common used solvent water.

This means that in a solution there is usually more solvent than solute.

So, in the case of the hydrogen peroxide solution, since the proportion is $3\%$ to $97\%$ , the hydrogen peroxide is the solute and water is the solvent.
