Question

Balance the following chemical equations : (i) S(s) + H2SO4(aq) → H2O(l) + SO2(g) (ii) S(s) + HNO3(aq) → H2SO4(aq) + NO2(g) + H2O(l) (iii) Fe2O3(s) + CO(g) → Fe(l) + CO2(g) (iv) KMnO4(aq) + HCl(aq) → KCl(aq) + MnCl2(aq) + Cl2(g) + H2O(l) (v) MnO2(s) + HCl(aq) → MnCl2(aq) + H2O(l) + Cl2(g)

Answer 1

S+ h2so4 → 2h2O + SO2

2S + 2HNO3 → H2SO4 + NO2

Fe2O3 + 3CO → 2Fe + 3CO2

KMNO4 + HCL → KCL + MNCL2 + CL2 + H2O

MNO2 + HCL → MNCL2 + H2O + CL2

ok ur answer and please mark
