Balance the following equations (a) H2SO4+ NaOH = Na2SO4+H2O (b) Ba(OH)2+ HBr =BaBr2 + H2O (c) KCN + H2SO4 = K2SO4+HCN (d) Al + HCl = AlCl3 + H2O (e) CH4 + O2 = CO2 + H2O

(a).H₂SO₄ + 2 NaOH = Na₂SO₄ + 2 H₂O

(b).Ba(OH)₂ + 2 HBr = BaBr₂ + 2 H₂O

(c) .2 KCN + H₂SO₄ = K₂SO₄ + 2 HCN

(d).Equation Al+HCl=AlCl₃+H₂O is an impossible reaction
Please correct your reaction or one of the suggestions is given below:
Al + HCl = AlCl₃ + H₂
Balanced equation:
2 Al + 6 HCl = 2 AlCl₃ + 3 H₂

_(e)  CH₄ + 2 O₂ = CO₂ + 2 H₂O
