1) What is the best reason as to why chemical equations need to be balanced? * To indicate the same number of moles on each side of the arrow. To indicate that atoms, and therefore mass, is conserved in a chemical reaction. To indicate the same number of molecules on each side of the arrow. O To indicated the same number of compounds on each side of the arrow.
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.
