What is formed when a metal carbonate breaks down by thermal decompostion?

Answer 1

metal oxide and carbon dioxide

Na2CO3(s) + heat -----> Na2O(s) + CO2(g) [not decomposed in normal conditions as Na2CO3 is very stable]

MgCO3(s) + heat -----> MgO(s) + CO2(g)

CoCO3(s) + heat -----> CoO(s) + CO2(g)

CuCO3(s) + heat -----> CuO(s) + CO2(g)

these are some examples from which you can get help.

Answer 2

Carbonic acid specifically can decompose into carbon dioxide and water. I'm not sure exactly what you mean by "such as carbonic acid". Some acids decompose more or less readily; others don't, but each of them has its own unique products (water is often one of them, since many acids do contain both hydrogen and oxygen, but the other one will be "whatever is left over").

Answer 3

metal carbonate is formed example for metal carbonate is na2co3

Answer 4

metal carbonate+acid --> metal+salt+water+carbohushluh

Answer 5

When heated, metallic carbonates break down as: XCO3 + heat -> XO + CO2 (X represents the metal).

Answer 6

Metal carbonate --> Metal Oxide + Carbon dioxide

example:

CaC03 --> CaO + CO2

Answer 7

Metallic carbonates decompose in heat to produce metal oxides and carbon dioxide. Example: MgCO3 --> MgO + CO2.

Answer 8

An oxide and cabon dioxide are formed.
