What does the law of conservation of mass say? The mass of the reactants is greater than the mass of the products in a chemical reaction. The mass of the reactants is less than the mass of the products in a chemical reaction. The mass of the products in a chemical reaction is unrelated to the mass of the reactants. The mass of the products in a chemical reaction is equal to the mass of the reactants.

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates). 

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
