Which of these equations is balanced? a. 3 h2so4 + 2al → al2(so4)3 + 3h2 b. 2kcl + pb(no3)2 → kno3 + pbcl2 a b a and b neither

A.) 3 H2SO4 + 2 Al > Al2(SO4)3 + 3 H2
6 H+ +3 S +12 O +2 Al> 2 Al + 3S + 12O + 6H+
This one is balanced, with 6 H, 3 S, 12 O, and 2 Al on both sides.
B.) 2KCl + Pb(NO3)2 > KNO3 + PbCl2
2K + 2Cl + Pb + 2N +6 O > 1 K + 1 N+ 3 O + Pb + 2 Cl
This one is not balanced as there is 2 K, 6 O and 2 N on the reactants side but only 1 K, 3 O, and 1 N on the products side.
Therefore, only A.) is balanced

Only equation A is balanced.
To balance equation B, simply add another molecule of KNO3, so the final equation would be:
2KCl + Pb(NO3)2 ---> 2KNO3 + PbCl2
