Question

(i) Explain the reactions of different metals with hot water, cold water and steam. Give the
balanced chemical equation involved.
(ii) Give one use of tin plating in daily life.​

Answer 1

Explanation:

i.Sodium reacts explosively with cold water. On the other hand, metals such as iron do not react with cold water or hot water. However, it reacts with steam to give their respective oxides and hydrogen gas. Thus, metals react with water to form metal oxides and hydrogen gas.

ii.The tin plating process is used for various purposes,but the most common use of tin plating is to produce a corrosion proof metal surface which is very useful in our daily lifestyle. The tin plated corrosion resistance is effective,cheap and light weight which is ideal for daily usage.

Answer 2

Answer:

Tin plating on any metal surfaces helps to resist corrosion
