the answer should be C beacuse zinc reacts with steam to give zinc oxide and liberate hydrogen gas so it means it neuther reacts with cold water nor hot water. note hot water is not the same as steam
The reactivity of zinc with water can be summarized as follows:
- Zinc does not react with cold water.
- Zinc reacts with steam (hot water vapor) to form zinc oxide and hydrogen gas.
Given this understanding, let's evaluate the statements:
A. **Zinc heated to redness reacts with steam to give oxygen and zinc oxide**: This is incorrect. The products of the reaction are zinc oxide and hydrogen, not oxygen.
B. **Zinc heated to redness reacts with steam to give oxygen and hydrogen**: This is incorrect. The products are zinc oxide and hydrogen, not oxygen and hydrogen.
C. **Zinc does not react with hot or cold water**: This is incorrect. Zinc does react with steam (hot water vapor).
D. **Zinc reacts with hot water to form zinc oxide and hydrogen**: This is correct. When zinc reacts with steam, it forms zinc oxide and hydrogen gas.
E. **Zinc reacts very easily with cold water to give zinc oxide and hydrogen**: This is incorrect. Zinc does not react with cold water.
Therefore, the correct statement is:
D. Zinc reacts with hot water to form zinc oxide and hydrogen.
The answer should be C because naturally zinc, aluminum, and iron does not react with cold water but with steam to liberate metallic oxide and hydrogen
Please, Myschool should cross-check the answer. The correct answer is C. Zinc does not react with hot water or cold water, it only reacts with steam to form its oxide and liberate hydrogen gas
The correct statement is C. Zinc does not react with hot or cold water. Zinc only reacts with steam when heated to redness, producing zinc oxide and hydrogen. The balanced chemical equation for this reaction is:
Zn(s) + H2O(g) → ZnO(s) + H2(g)
Therefore, options A, B, D, and E are incorrect because they describe reactions that either don't occur or don't accurately represent the products of the reaction between zinc and water/steam.
Zinc does not react with cold water but it reacts with steam at red heat liberating because its higher than hydrogen in the activity series. Summarily the reaction produce zinc oxide and hydrogen which makes D very suitable for the answer. 
zinc does not react with hot water because of its protective layer.... hence the appropriate answer should be that zinc does not react with cold and hot water, only react with steam to form zinc oxide and hydrogen
