Question

Zn(s) + H2 SO4 (aq) → ZnSO4 (aq) + H2 (g) is an example of

(A) precipitation reaction (B) endothermic reaction (C) evolution of gas

(D) change in color.

Please help guys..❤​

Answer 1

HEYYO❤️

ANSWER---> IT IS AN EXAMPLE FOR PRECIPITATION REACTION AS ZNSO4 IS A WHITE COLOUR PRECIPITATE...GAS IS ALSO EVOLVED IN THIS PROCESS...

STAY SAFE❤️

Answer 2

Answer:

(C) evolution of gas

Explanation:

Zn(s)+H2SO4(aq) upward push to ZnSO4(aq)+H2(g) is an instance of evolution of fueloline.

The response Zn(s)+H2SO4(aq) →ZnSO4(aq) + H2(g) is a displacement response wherein Zinc displaces H2 to shape ZnSo4. As a result, H2 fueloline is the developed because of this response. Hence, the best choice is evolution of fueloline.

Other options, including precipitation response, isn't accurate as it's far a displacement response and is exothermic.

So,the answer is C) evolution of gas.
