What is the limiting reactant in each of the following reactions?
a 0.1 mol Sb. O react with 0.5 mol H2SO4
Sb.06 +6H2SO4 → 2Sb2(SO4)3 + 6H2O
b 0.20 mol AsClz react with 0.25 mol H2O
4AsCl3 + 6H2O → As 06+12HCI
c 0.25 mol copper react with 0.50 mol dilute
HNO3 according to the equation:
3Cu+8HNO3
→ 3Cu(NO3)2 + 4H2O+2NO
d 0.10 mol NaCl react with 0.15 mol MnO2 and
0.20 mol H2SO4
2NaCl + MnO2+2H2SO4
→ Na2SO, +MnSO4 +2H2O + Cl2
