C. Balance the following equations. Write the oxidation and reduction half-reactions involved. a. MnO2(s) + HCl(aq) → MnCl2(aq) + Cl2(g) + H2O(1)
b. S(s) + HNO3(aq) → SO3(g) + H2O(l) + NO2(8)
C. H2C204+ K2 CrO4(aq) + HCl(aq) → CrCl3(aq) + KCl(aq) + H2O(l) + CO2(g)

i believe that it is a exoplanet

i would say b

explanation:

but i think i would need more information than that

consider the reaction below.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
