How many moles of H2O form when 4.5 moles O2 reacts?

Chemistry
1 answer:
mart [117]2 years ago
4 0

Explanation:

Start with a balanced equation.

2H2 + O2 → 2H2O

Assuming that H2 is in excess, multiply the given moles H2O by the mole ratio between O2 and H2O in the balanced equation so that moles H2O cancel.

5 mol H2O × (1 mol O2/2 mol H2O) = 2.5 mol O2

Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.

A company desires to produce nickel from refining nickel oxide and sulfide ores. the first step of the process will produce a ni
inn [45]
Answer is: increase the concentration of NiCO₄ and <span>withdraw CO from the products as it is forming.

Balanced chemical reaction: NiCO</span>₄(g) ⇄ Ni(s) + 4CO(g).
According to Le Chatelier's Principle the position of equilibrium moves to counteract the change:
1) the position of equilibrium will move to the right, so that the concentration of nickel carbonyl gas decreases again and produce more nickel.
2)  the position of equilibrium will move to the right, if we decrease concentration of carbon monoxide, more nickel carbonyl gas will decompose and produce more nickel.
