Answer to Question #200133 in Chemistry for marianna

Question

NaCl + H2SO4 —> NaHSO4 + HCl If a reaction vessel contains 10.0 g of sodium chloride and 12.0 g of sulfuric acid, what is the limiting reactant? 

Answer 1

NaCl + H₂SO₄ —> NaHSO₄ + HCl

n = m / M

M (NaCl) = 58.4 g/mol

M (H₂SO₄) = 98.1 g/mol

n (NaCl) = 10 / 58.4 = 0.17 mol

n (H₂SO₄) = 12 / 98.1 = 0.12 mol

According to the equation, n(NaCl) = n(H₂SO₄). From the given reactant amounts, H₂SO₄ is the limiting reactant.
