Question #c6e7b

Answer 1

The heating of solid copper(II) carbonate is a thermal decomposition reaction . The addition of heat energy causes chemical bonds to break and the reactant decomposes into two products.

Word Equation:

copper(II) carbonate + heat `rarr` copper(II) oxide + carbon dioxide

Molecular Equation:

`"CuCO"_3("s")` + heat `rarr` `"CuO"("s")` + `"CO"_2("g")`

This reaction is accompanied by a color change. The green copper(II) carbonate turns into black copper(II) oxide.
