Question

solve this chemistry problem please ....
​

Answer 1

1). zinc granules react more readily with respect with zinc metal. Hence , H2SO4 will react more readily with Zinc granules.

2).HCl is more reactive acid than H2SO4 since Hydrogen and Chlorine have more affinity towards each other.

Therefore more Hydrogen will be produced.

3).Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen.

4).Zn + 2NaOH → Na2ZnO2 + H2 Zinc react with excess sodium hydroxide to form sodium zincate(Na2ZnO2) along with hydrogen gas.

Hope it'll help !!!

Please let me know if I have commited any error by mistake.
