Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product therefore it follows law of conservation of mass.

Total mass of reactants = total mass of product, therefore, law of multiple proportions is followed

Amount of Fe₂O₃ can be increased by taking anyone of the reactants (iron or oxygen) in excess

Amount of Fe₂O₃ produced will decrease if the amount of anyone of the reactants (iron or oxygen) is taken in excess.

2Mg(s) +O₂(g) \(\Rightarrow\) 2MgO(s)

C₃H₈(g)+ O₂(g) \(\Rightarrow\) CO₂(g)+ H₂O(g)

P₄(s) + 5O₂(g) \(\Rightarrow\) P₄O₁₀(S)

CH₄(g)+ 2O₂(g) \(\Rightarrow\) CO₂(g)+ 2H₂O(g)

A molecule of a compound has atoms of different elements

A compound cannot be separated into its constituent elements by physical methods of separation

A compound retains the physical properties of its constituent elements

The ratio of atoms of different elements in a compound is fIxed
