Chemical CalculationsCHEMCAL CHANGEChemical changes have three main features:1. New substances are made2. There is an energy change between the reacting system andits surroundings3. There is a fixed relationship between the masses of thereactants and products-this is called the stoichiometry ofthereactionStoichiometry is the name given to the property ofpure substances to react together in whole numberratios of particles.Chemical changes are nearly always written asequations showing the reactants and productssymbolically in the form of some kind of formula.6

There is a fixed relationship between the masses of the reactants and products-this is called the stoichiometry of the reaction Stoichiometry is the name given to the property of pure substances to react together in whole number ratios of particles. Chemical changes are nearly always written as equations showing the reactants and products symbolically in the form of some kind of formula
Chemical CalculationsDIEEERENTKINDSOFFORMULAEmpirical formula shows the simplest whole numberratio of atoms in the particles of the substance, e.g. C,H.Oand CH.Molecular formula shows the actual number of atomsin a particle of the substance, e.g. C,H,O and C,H2Structural formula shows the arrangement of atoms intheparticleEither written as, e.g. CH,CH,OH and HCCHOr drawn asHHHH-C=CH?HHSome people call the drawn formulas displayedformulas, but this is not common.7
7 Chemical Calculations DIFFERENT KINDS OF FORMULA Empirical formula shows the simplest whole number ratio of atoms in the particles of the substance, e.g. C2H6O and CH. Molecular formula shows the actual number of atoms in a particle of the substance, e.g. C2H6O and C2H2 . Structural formula shows the arrangement of atoms in the particle Either written as, e.g. CH3CH2OH and HCCH Or drawn as Some people call the drawn formulas displayed formulas, but this is not common
