Study the chemical equations in the table.
Equation Number Balanced Equation
1 2Al(s)+3Cl2(g)?2Al3+(aq)+6Cl?(aq)
2 HCl(g)+NH3(g)?NH4Cl(s)
3 10H+(aq)+SO2?4(aq)+8I?(aq)?4I2(s)+H2S(g)+4H2O(l)
Classify each reactant in the chemical equations as an oxidizing agent, a reducing agent, or neither.
Oxidizing agent
Reducing agent
Neither
Calculate the increase or decrease in the oxidation state for each element listed as it changes from a reactant to a product. Use a negative sign to show a decrease in oxidation state.
aluminum, beginning in the reactant Al
nitrogen, beginning in the reactant NH3
iodine, beginning in the reactant I?
sulfur, beginning in the reactant SO2?4
