Question

Sodium reacts with chlorine gas to produce sodium chloride if 10 moles of chlorine reacts with 5 moles of sodium, which reactant will be the limiting reactant

Answer 1

Equation:2Na+Cl2-->2NaCl
no. of mole of Na=5 moles
no. of moles of Cl2=10 moles
since 5 moles of Na will react with (5/2)=2.5 moles of Cl2. Therefore Na is the limiting reactant.
