Answer:
Hydrogen is the limiting reactant.
Step-by-step explanation:
as per the balanced equation
2H2 + O2 =2H2O
A B
moles of H2=2 moles
moles of O2=2moles
short formula to find limiting reactant is;
moles of A / coefficient of A from balanced equation=moles of B / coefficient of B from balanced equation
2 / 2 = 2 / 1
1 = 2
H=1 O=2
hydrogen is the limiting reactant
