Answer:

D. 2NH₃(g) ⟶ N₂(g) + 3H₂(g)

Explanation:

A chemical equation must show the correct formulas for reactants and products.

A and B are wrong, because they have NH₃ as a product.

C is wrong. H₃ does not exist.

A is correct. The equation for the decomposition of ammonia is

2NH₃(g) ⟶ N₂(g) + 3H₂(g)

Question 21
Mumz [18]
There are 2 moles of O stones present in 88 grams of CO2. Why? Well, we can find the amount of moles present in 88 grams of CO2 by dividing the mass by the molar mass. The mass of CO2 comes out to be 88 grams. The molar mass of CO2 comes out to be 44 grams. Because 88 is the mass of CO2 and 44 is the molar mass of CO2, we can divide 88 by 44 to identify that there are 2.0 moles of O atoms present in 88 grams of CO2.

Your final answer: There are 2.0 moles of O atoms present in 88 grams of CO2. Your final answer to this question is D, or 2.0 moles. If you need to better understand, let me know and I will gladly assist you.
