Answer:
0.440 moles of NH₃ are produced
Explanation:
First of all, we need to determine the limiting reactant by the stoichiometry.
Equation reaction is: N₂(g) + 3H₂(g) ⟶ 2 NH₃(g)
1 mol of nitrogen needs 3 moles of hydrogen to react
Therefore 0.220 moles of N₂ will need (0.220 . 3) / 1 = 0.660 moles of H₂
As we have 0.717 moles of H₂ and we need 0.660, the hydrogen is the excess reagent, therefore, the N₂ is the limiting reactant
3 moles of H₂ need 1 mol of N₂ to react
Then, 0.717 moles of H₂ will react with (0.717 . 1) / 3 = 0.239 moles of N₂
We do not have enough N₂
After complete reaction → ratio is 1:2
1 mol of N₂ reacts to produce 2 moles of ammonia
Therefore 0.220 moles of N₂ will produce (0.220 . 2) / 1 = 0.440 moles of NH₃
Animals get their food by preying on other species or scrounging for scraps they can find. Some eat other animals and some eat plants.
Plants get their food by absorbing minerals and water from the ground and absorbing carbon dioxide from the air through their leaves. They then also absorb sunlight and all of those components are made into food for the plant. Simple answer is through photosynthesis.
Answer: The molar mass of a single hydrogen atom is 1 g/mol.
Explanation: The molar mass of a hydrogen molecule is 2 x 1 g/mol = 2 g/mol. Likewise, a molecule of oxygen gas has the formula O2 .
