sulphate heptahydrate Memorize picture 24 ions only systematic names Memorize prefixes for nomenclature Know table 25 polyatomic ions Acids are gaseous compounds dissolved in Water apter 3 AMU is defined as 112 the Weight of a carbon l2 atom Combustion burning in the presence of oxygen results in CO2 and H20 Hydrocarbons consist of hydrogen and carbon atoms Carbohydrates consist of hydrogen carbon and oxygen atoms Chemistry the study of the rearrangement of matter due to the flow of energy Common molecular forms S3 C60 P4 A reaction is the rearrangement of atoms Molar equivalencies can convert to higher amounts using molecular formula Formula Weight molar mass apter 4 Solute is substance being dissolved Solvent does the dissolving Solution is the final combination Water will dissolve ionic compounds and polar compounds Hydration breaks up ionic compounds 0 Electrical conductivity ow of electricity in a solution shows the presense of ions 0 Electrolyte solid substance that conducts electricity in water 0 Ions are SolvatedHydrated when in water 0 fu formula units can be used to denote any compound 0 compound X M concentration of compound is x molar 0 NO339 salts are soluble 0 Naquot Kquot NH4quot salts are usually soluble 0 Cl usually soluble except when in AgCl 0 SO4239 are soluble except when in BaSO4 PbSO4 CaSO4 0 OH slightly soluble ex NaOH KOH CaOH2 usually insoluble 0 S2 CO3239 PO4339 only slightly soluble usually insoluble 0 Know table 41 0 M1V1 M2V2 Morality and Volume are related when diluting ect 0 Solubility of ions in water depends on Electrostatic force between ions and attractive forces between ions and water 0 AcidB ase Reaction 0 Transfer of a proton 0 Usually creates water or a weak acid 0 Forms an aqueous salt 0 BronstedLowry
