Chemical changes

Explanation:

a)Burning a piece of charcoal - chemical change

b) Heating copper (ii) carbonate strongly - chemical change

c) Heating Zinc oxide strongly - chemical change

The given types of reaction indicates chemical changes. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible and hence, it is a permanent procedure.

 Burning of charcoal produces a new kind of produces in the combustion process.

Both heating of copper(ii)carbonate strongly and zinc oxide will lead to a decomposition reaction in which new compounds are formed.

the ratio of the conjugate base to the acid required to attain the desired ph.
