Answer 2

Hello!

Here is the answer for your question!

Question:- Which of the following metals reacts with cold water, hot water and steam -- potassium, magnesium and zinc. Also write their chemical equation.

------------------------------------------------------------------

Answer:-

• Potassium is the metal that reacts with cold water, it reacts with cold water to produce potassium hydroxide and hydrogen gas.

2K(s) + 2H2O(l) → 2KOH(aq) + H2(g)

• Magnesium is the metal that reacts with hot water, it reacts with hot water to produce magnesium hydroxide and hydrogen gas.

Mg(s) + 2H2O(l) → Mg(OH)2(s) + H2(g)

• Zinc is the metal that reacts with steam, it reacts with steam to produce zinc oxide and hydrogen gas.

Zn(s) + H2O(g) → ZnO(s) + H2(g)
