Balanced net ionic equation: 3) Get two medium test tubes. Into one, place about 2 ml. of a solution of hydrochloric acid. Into the other add a small amount of solid sodium carbonate. Note the appearances of the contents in the two test tubes and then mix them together noting any changes that have taken place. Change(s) that took place when the test tube contents were mixed: Balanced chemical equation: Balanced ionic equation: Balanced net ionic equation:
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.
