Question

Give one example of thermal decomposition of a carbonate

Answer 1

Answer:

Eg - when calcium carbonate is strongly heated in the absence of air , it breaks down to give calcium oxide and carbon dioxide. Eg - On passing current water breaks down to give hydrogen and oxygen

Answer 2

Answer:

MARK ME BRAINLEST PLEASE

HEY MATE HERE IS YOUR ANSWER

Explanation:

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate. Students are also asked to research the large-scale applications of these processes.
