Reduction of $2.4 \ g$ of $FeO$ with hydrogen yields $1.68 \ g$ of $Fe$. In another experiment,$2.9 \ g$ of $FeO$ on reduction with hydrogen yields $2.03 \ g$ of $Fe$. These results illustrate the law of:

The combining ratios of hydrogen and oxygen in water and hydrogen peroxide are $1: 8$ and $1: 16$. Which law is illustrated in this example?

$1.7 \, g$ of silver nitrate is dissolved in $100 \, g$ of water. Another $0.585 \, g$ of sodium chloride is dissolved in $100 \, g$ of water and added to the first solution,resulting in a chemical reaction. $1.435 \, g$ of silver chloride and $0.85 \, g$ of sodium nitrate are produced. Which law is followed by the above information?

Which one of the following sets of compounds correctly illustrates the law of reciprocal proportions?

After a chemical reaction,the total mass of reactants and products

Irrespective of the source,a pure sample of water always yields $88.89\%$ mass of oxygen and $11.11\%$ mass of hydrogen. This is explained by the law of
