Ammonia, nh3, is widely used as a fertilizer and as an ingredient in many household cleaners. how many moles of ammonia are produced when 6 mol of hydrogen gas reacts with an excess of nitrogen gas?

4 mol of ammonia are produced

Explanation:

Let's identify the reaction:

N₂  + 3H₂  →  2NH₃

Ratio between H and ammonia is 3:2

3 mol of hydrogen are needed to make 2 mol of NH₃

6 mol of hydrogen, will make ( 6 .2) / 3 = 4 mol

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
