Chemistry  Pure substance : any matter made up of one type of element/atom Element/compounds:  symbols, cannot break down/formulas broken down from molecules Mixture:  any matter that is made up of more than one type of atom Homogenous/Heterogeneous:  1 part/many parts Properties Physical: Change of state Change in shape Reversible Dissolving Chemical: Change of colour Release of gas Hard to reverse Release of heat Precipitate Ions: -Elements which have gained or lost electrons to make their outer orbital’s filled -Net charge of 0, indicated by a + or -, depending on amount of extra electron -CATION = + -ANION = - -Based on their column on the periodic table and the amount of valence electrons, they will make bonds with  each other… Add up to 8

-Electrons move from one atom to another to make it full -Electrolytes: a compound that separates into ions when dissolved in water, producing a solution that  conducts electricity Ionic Compounds Naming -metal followed by the nonmetals +ide. -Transitional metals need (XX) to indicate its charge -Criss Cross method for formulas Polyatomic compounds -an ion made up of more than one atoms that acts as a single particle Naming/formula -write the name of the cation, then the ide after the anion -criss cross to determine the charges Molecular compounds/covalent compounds -compounds that bond together by sharing electrons not by giving them away -some contain diatomic particles that always come in a pair of two - HOFBrINCl -Naming uses a set of some common molecular names -Second term/first that is more than 1 will use prefix system -no charges Reactants and product -Chemical reactants come together and react to form a product Decomposition -single compound breaks down into other elements/compounds AB -> A +B

Synthesis -Opposite to decomp A+B -> AB Single Displacement -one element replaces another in a compound, leaving an element alone A+BC -> AC+B Double Displacement -elements in two compounds switch places with others in the formula AB+CD -> AD+CB -Combustion -rapid reaction with oxygen to create oxides -fuel + oxygen -> oxides + energy Hydrocarbons -hydrocarbons + oxygen -> carbon dioxide + water Incomplete combustion -releases CO, CO2, H2O, and C -happens when there aren’t enough oxygen Oxidization -metals reaction with oxides in a slow process to produce an oxide on a surface Law of conservation of mass -the mass of the reactant will equal the mass of the product -means that we have to balance equations to have them equal and work with the law -using coefficients and multipliers Word equations
