When heated, nickle (ii) carbonate undergoes a decomposition reaction. write a balanced equation to describe this reaction.

Ni C03 ---> CO2 + NiO

Explanation:

Ni C03 ---> CO2 + NiO

When heating nickel carbonate at elevated temperatures, 400 ° C for example, decomposes giving as products carbon dioxide and nickel oxide.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
