Balanced Chemical Equations

3)

The following equation is not balanced

CaSO4 + AlCl3 —> CaCl2 + Al2 (SO4)3

Notice that SO4 appears in two different places in this chemical equation. SO4^2- is a polyatomic ion called "sulfate".

(i) What number should be placed in front of CaSO4 to give the same total number of sulfate ions on each side of the equation?
CaSO4 +ALCL3 —> CaCl2 + Al2 (SO4)3

(ii) MnI2 (aq) + AgNO3(aq) –? AgI(s) + AgI(s) + Mn(NO3)2 (aq)
Express your answer as a chemical equation. Identify all of the phases in your answer.

(iii) NaN3 (s) -? Na(s) + N2 (g)
Express your answer as a chemical equation. Identify all of the phases in your answer.

(iv) Cl2(g) + NaOH(aq) —> NaCl(aq) + NaClO3(aq) + H2O(l)
Express your answer as a chemical equation. Identify all of the phases in your answer.

(v) BaCl2(aq) + H3PO4(aq) —> H3PO4(aq) —> Ba3 (PO4)2(s) + HCl(aq)
Express your answer as a chemical equation. Identify all of the phases in your answer.

Please show each step and explain each step with as much detail including why you took so and so step. Thank You
