Classify each of the following redox reactions as a combination, decomposition, or displacement reaction, give a balanced molecular equation for each, as well as total and net ionic equations for parts (b) and (c), and identify the oxidizing and reducing agents. (Type your answer using the format H2O for H2O and (NH4)2CO3 for (NH4)2CO3. Do not include state symbols in the answers. Use the lowest possible coefficients. Enter 0 if necessary. Do not leave any box blank.) :
(a) S(s) + O2(g) gives SO2(g)
(b) CsI(aq) + Cl2(aq) gives CsCl(aq) + I2(aq)
(c) Ni(NO3)2(aq) + Cr(s) gives Ni(s) + Cr(NO3)3(aq)
