redox reactions? For each redox reaction,
determine which atom is oxidized and which
is reduced, and identify the oxidizing agent
and the reducing agent.

MgCO3(s) + H2O(l)
b.2KNO3(s)→2KNO2 (s) + O2(8)
c. H2(g) + CuO(s) → Cu(s) + H2O(1)
d. NaOH(aq) + HCl(aq) →
NaCl(aq) + H2O(1)
e. H2(8) + Cl2(g) → 2HCl(8)

Answer:

a. MgO(s) + H2CO3(aq) →  MgCO3(s) + H2O(l) DOUBLE DISPLACEMENT REACTION.

b. 2KNO3(s)→2KNO2 (s) + O2(8) DESCOMPOSITION REACTION.

c. H2(g) + CuO(s) → Cu(s) + H2O(1) SINGLE DISPLACEMENT REACTION.

d. NaOH(aq) + HCl(aq) →  NaCl(aq) + H2O(1) COMBUSTION  REACTION.

e. H2(8) + Cl2(g) → 2HCl(8) SYNTHESIS REACTION.

f. SO3(g) + H2O(1)→ H2SO4(aq) SYNTHESIS REACTION.
