What is the solid produced when zinc carbonate decomposes?

Answer 1

Zinc oxide.

Zinc carbonate, #"ZnCO"_3#, undergoes thermal decomposition to form zinc oxide, #"ZnO"#, a solid that is white in color when cold and yellow in color when hot, and carbon dioxide gas, #"CO"_2#

#"ZnCO"_ (3(s)) stackrel(color(white)(a)color(red)(Delta)color(white)(aaa))(->) "ZnO"_ ((s)) + "CO"_ (2(g))# #uarr#

This reaction is characteristic to metal carbonates, which decompose when heated to form the oxide of the metal and carbon dioxide gas.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
