Answer:
change in composition
a substance decomposing
burning
Explanation:
A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes (evolution or absorption of energy in form of heat or light or both).
This process is often irreversible.
- Chemical changes involves changes in mass.
- It requires considerable amount of energy.
- It leads to the production of new kinds of matter
Now, processes such as burning and decomposition are chemical changes and are not easily reversible.
Since new kind of matter is formed, there is a change in composition.
Melting is a physical change that is easily reversed.
Other examples of chemical changes are rusting of iron, precipitation and souring of milk.

Answer:1 mol
Explanation:
the conversion from mol to volume of gas at STP is 22.4L, meaning that the amount of mols in a gas of volume 22.4L at STP is one mol.

Answer:
ZnCO3+H2SO4= ZnSO4+H2CO3
Explanation:
ZnCO3+H2SO4= ZnSO4+H2CO3
<u>Zinc is more reactive than hydrogen, hence, it will displace Hydrogen from Sulfuric acid.</u>
