1. (Combo) chromium (III) + bromine =

2. (D.R) potassium chloride + nickel II chromate =

3. (Decomp) carbon tetrachloride =

4. (S.R.) aluminum sulfite + barium =

5. (Decomp) magnesium oxide =

6. (D.R.) calcium nitrate + copper I carbonate =

7. (S.R.) nickel II phosphate + manganese II =

8. (D.R.) Mercury II oxide + hydrogen sulfite =

9. (Combo) iron II + oxygen =

10. (S.R.) zinc phosphate + aluminum =

Answer 1

1. 2 Cr + 3 Br2 → 2 CrBr3
2. 2 KCl + NiCrO4 → NiCl2 + K2CrO4
3. CCl4 → C + 2 Cl2
4. Al2(SO3)3 + 3 BaCl2 → 2 AlCl3 + 3 BaSO3
5. 2 MgO → 2 Mg + O2
6. Ca(NO3)2 + Cu2CO3 → CaCO3 + 2 Cu(NO3)2
7. Ni3(PO4)2 + MnSO4 → Mn3(PO4)2 + NiSO4
8. HgO + H2SO3 → HgSO4 + H2O
9. 4 Fe + 3 O2 → 2 Fe2O3
10. 3 Zn3(PO4)2 + 2 Al → 2 AlPO4 + 9 Zn
