True or False? If the statement is true, write true. If it is false, write false, and change the sentence to make it true! We use the ideal gas law when a gas changes. The universal gas constant, R, is .0821 when we use mm Hg as our unit for pressure. The ideal gas law allows us to figure out a fourth variable about a gas when the other 3 are given. One mole of any gas, at 1 atm of pressure and 0°C, occupies a volume of 44.0 liters. The four units that must always be used when using the ideal gas law are liters, atm, Kelvin, and grams. A real gas does not have a volume of zero, and the molecules actually interact with one another.

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.
