Balance each of the following chemical equations. Give your answer as coefficients ?

1) MnI2(aq)+AgNO3(aq)→AgI(s)+Mn(NO3)2(aq)

2) HOCl(aq)+HCl(aq)→H2O(l)+Cl2(g)

3) HClO4(l)+P2O5(s)→Cl2O7(l)+HPO3(s)

4) FeS(s)+HCl(aq)→FeCl2(aq)+H2S(g)

1 Answer

  • 1)

    MnI2(aq) + 2 AgNO3(aq) → 2 AgI(s) + Mn(NO3)2(aq)

    2)

    HOCl(aq) + HCl(aq) → H2O(l) + Cl2(g) [balanced as written]

    3)

    2 HClO4(l) + P2O5(s) → Cl2O7(l) + 2 HPO3(s)

    4)

    FeS(s) + 2 HCl(aq) → FeCl2(aq) + H2S(g)
