Kr 4d10 5s2 5p2 would be your answer.
The number of moles of oxygen (O2) required to completely react with 27.4 mol of H2 is 13.7 moles.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated using stoichiometry as follows:
The following balanced chemical equation is given as follows:
2H2 + O2 = 2H2O
According to this question, 2 moles of hydrogen gas (H2) reacts with 1 mole of oxygen gas (O2).
This means that 27.4 moles of hydrogen gas (H2) will react with 27.4/2 = 13.7moles of oxygen gas.
Therefore, the number of moles of oxygen (O2) required to completely react with 27.4 mol of H2 is 13.7 moles.
