48. Are these data sets on chemical changes consistent with the law of conservation of mass?(a) A 12.8-g sample of sodium completely reacts with 19.6 g of chlorine to form 32.4 g of sodium chloride.(b) An 8-g sample of natural gas completely reacts with 32 g of oxygen gas to form 17 g of carbon dioxide and 16 g of water
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.

law of conservation of mass?
(a) A 12.8-g sample of sodium completely reacts with 19.6 g
of chlorine to form 32.4 g of sodium chloride.
(b) An 8-g sample of natural gas completely reacts with
32 g of oxygen gas to form 17 g of carbon dioxide and
16 g of water
