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.
Correct the ones that are marked wrong:
![Prelab for Table III:
Write the 3 steps for the net ionic equation for the reactions listed below. First one is done for
you. Assume all reactants are aqueous 0.1 M solutions except where other phases and
concentrations are noted. The molarities that are shown are for experimental purposes and
do not affect the net ionic equations. You will tear this out along with the other tables and
place on the instructor's bench. Write neatly please

1 (b) BaSO4(s) + HCl (aq) -----------> No reaction
BaSO4 is insoluble solid. It is not soluble in HCl. Hence, there is no possibility of reaction between BaSO4 and HCl.
2 (b) NiCO3 reacts with HCl and liberates CO2.
NiCO3 (s) + HCl NiCl2 + H2O + CO2
