Make atoms equal to each other according to amounts on either side of the equation, taking into account . • The coefficients the lowest amount possible. • Ex1: _Ag20(s)_Ag + O2 2Ag20(s)4Ag + O2
Ex. 2 _CdBr2(aq)+ _Na2S(aq) _CdS(s) + _BrNa(aq)
Ex. 2 CdBr2(aq)+ Na2S(aq) CdS(s) + 2BrNa(aq)
RULE OF THUMBS • You should probably balance hydrogen and oxygen last, it tends to make it easier. • Also, you can make a chart to see how many are on each side. • You should already know everything on this powerpoint.
