Question

Give balanced equation (a)dilute sulphuric acid react with aluniumpowder (b) potassium carbonate react with hydrochloric acid (c) potassium hydroxide react with nitricacid (d) zinc react with sodium hydroxide solution

Answer 1

1-H2SO4+Zn=ZnSO4+H2 (release)
2-K2CO3 + 2HCl --> 2KCl + H2O + CO2 3-KOH + HNO3=HOH + KNO34-2NaOH+Zn=Na2+ZnO3+H2

Answer 2

H2SO4 + Zn======>ZnSO4+H2 

K2CO3 + 2HCl======> 2KCl + H2O + CO2

KOH + HNO3========>HOH + KNO3

2NaOH+Zn==========>Na2+ZnO3+H2
