Kinetic molecular theory 
Molecules of gas are so small that their mass and volume are considered insignificant
Gas molecules are always in constant random motion
The average kinetic energy of gas molecules is directly related to its temperatures
In Boyle's law, when a gas is pressurized
The volume will decrease (volume is inversely proportional to pressure at constant temperature)
In Charles' law, the relationship between the volume and temperature of a gas in an isobaric system
Are directly proportional
Applying Boyle's Law, if the pressure is doubled
The volume will reduced to half
0 oC is equal to 273 since K = oC + 273 so K = 0 oC + 273
Reminder: Try practice to used the formula (3 or 4 problems are included in the summative test)
In pressure, 1 atm = 760 torr, ex 2 atm = 1520 torr (since 2 x 760 = 1520), 3 atm = 2280 torr
In Boyle's law temperature is constant
In Charles law pressure is constant
Law of conservation of mass 
The total mass of the reactants is equal to the total mass of the products
The number of atoms of the element on the reactant is equal to the number of atoms of the element on the product
In a chemical reaction, the mass the atoms of the reactants is equal to the mass of the atoms of the products
Covalent compound 
Non metal + non metal
Ionic compound 
Metal + non metal
Types of chemical reaction/predicting the products
