Which of the following factors would reduce the yield of a reaction?
NikAS [45]

The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.

<h3>What is a Chemical reaction?</h3>

This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.

A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.

When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

The molecular mass of air, at standard pressure and temperature, is approximately 28.97 g/mol. Calculate the mass of 3.33 moles
hoa [83]
Note: You are calculating mass which is determine the gram(g)
You will have to cancel out the mol
(28.97 g/mol) * mol will give grams by itself
Given the mass 3.33 moles of air
28.97 g/mol * 3.33 mol = 96.47 grams
Solution: 96.5 grams

What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)
lana [24]

Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come
