Question

The equation below shows hydrogen reacting with oxygen to produce water. 2H2 + O2 2H2O If 16 mol of oxygen were reacted with excess hydrogen gas, how many moles of water would be produced? 4.0 mol 8.0 mol 16 mol 32 mol

Answer 1

The answer would be 32mol

Answer 2

Answer : The moles of water produced will be, 32 moles

Explanation : Given,

Moles of oxygen = 16 moles

The given balanced chemical reaction is:

$2H_2+O_2\rightarrow 2H_2O$

From the balanced chemical reaction we conclude that,

As, 1 mole oxygen react to give 2 moles of water

So, 16 moles oxygen react to give $2\times 16=32moles$ of water

Therefore, the moles of water produced will be, 32 moles
