When a white powder (A) is strongly heat...

When a white powder (A) is strongly heated, it gives of a colourless, odourless gas (B) which turns lime water milky (C) and if the passage of this gas is continued the milkiness disappears and gives a solution (D). The solid residue (E) is yellow when hot, but turns white on cooling. Idnetify (A) to (E) with help of the equations.

To solve the problem step by step, we will identify each component (A to E) based on the information provided in the question and the chemical reactions involved. ### Step 1: Identify the white powder (A) The question states that a white powder (A) is strongly heated and produces a colorless, odorless gas (B). The solid residue (E) is yellow when hot and turns white on cooling. Based on the description, the white powder (A) is likely **Zinc Carbonate (ZnCO3)**. ### Step 2: Identify the gas (B) ...
