A few chemistry questions? c:

If you could help me out with these, that'd be so amazing. :) Thank you~!
It's 16 questions.... D: But they're quite simple I assume.!

1. Write a word equation for each chemical reaction in the space provided. 2NaI + Cl2 → 2NaCl + I2

2. Write a formula equation for each word equation in the space provided. magnesium + oxygen → magnesium oxide

3. Write a formula equation for each word equation in the space provided. calcium carbonate → calcium oxide + carbon dioxide

4. Identify each chemical equation as a synthesis, decomposition, single-displacement, or double-displacement reaction. 2H2O(l) → 2H2(g) + O2(g)

5. Identify each chemical equation as a synthesis, decomposition, single-displacement, or double-displacement reaction. Cl2(g) + 2KBr(aq) → 2KCl(aq) + Br2(l)

6. Identify each chemical equation as a synthesis, decomposition, single-displacement, or double-displacement reaction. CaO(s) + H2O(l) → Ca(OH)2(s)

7. Identify each chemical equation as a synthesis, decomposition, single-displacement, or double-displacement reaction. HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

8. Balance the following formula equations in the space provided. AgNO3 + CuCl2 → AgCl + Cu(NO3)2

9. Balance the following formula equations in the space provided. PbO2 → PbO + O2

10. Balance the following formula equations in the space provided. Zn(OH)2 + CH3COOH → Zn(CH3COO)2 + H2O

12. Consider the equation O2(g) + CS2(l) → CO2(g) + SO2(g). How does the equation violate the law of conservation of mass? How can the equation be rewritten to conform to the law of conservation of mass?

13. Write a balanced chemical equation for the following reaction: iron plus copper(I) nitrate yields iron(II) nitrate plus copper.

14. Tell what type of chemical reaction is represented by the following formula equation. Then balance the equation.KBr(aq) + Mg(OH)2(aq) → KOH(aq) + MgBr2(aq)

15. Use the activity series to determine if the following reaction is possible. If it is possible, write the products and balance the equation. If not, explain.4Cr(s) + 3O2(g) →
