Question

The carbonate of metal X is a white solid it decomposes when heated to form carbon dioxide and a yellow solid oxide. What is metal X

Answer 1

Hey Dear,

◆ Answer -

Metal X is lead.

◆ Explanation -

Lead oxide is white solid amorphous powder.

When lead carbonate (PbCO3) is heated, it is decomposed to lead oxide (PbO) and carbon dioxode (CO2).

PbCO3(s) + ∆ --> PbO(s) + CO2(g)

Carbon dioxide is a odourless & colorless gas. Lead oxide presents as yellow solid.

Hope this was helpful. Thanks for asking..
