A. Balance the following half-reaction in base, using smallest wholenumber coefficients. What is the coefficient forOH-in the balanced equation?
CrO42-(aq)ââ â Cr(OH)3(s)
B. Balance the following reaction in acid, using smallest whole numbercoefficients. What is the coefficient for H2Oin the balanced equation?
Ga(s) + MnO4-(aq)ââ â Ga3+(aq)+ Mn2+(aq)
(Hint, first balance each half-reaction separately.)
