Which of the follow is NOT true In a chemical reaction the products often have less mass than the reactants because matter is often lost as a gas in chemical reactions. The density of a liquid is greater than the density of a gas. O Heat is released in some chemical reactions and absorbed in other reactions. There is a limit to how small matter can be divided. Once the particle is a molecule, if it is divided the matter will be something different. At a given temperature and pressure, a mole of a gas has the same volume regardless of the gas.

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.
