answer -

13 is the last one

14 is the first one

explanation for number 13 - the law of conservation of mass means that the number of atoms of the products is more than the number of atoms in the reactants. the total amount of matter (atoms) before and after a chemical reaction (change), remains the same.

explanation for number 14 -  a chemical equation describes a chemical reaction. reactants are starting materials and are written on the left-hand side of the equation. products are the end result of the reaction and are written on the right-hand side of the equation.
