Chemical reactions?Easy 10 pts,best answer.? - easy chemical reactions for model cars

I am revising a paper for my last test trials next week, but I have no right answers, you can help me please? What is the balanced chemical reaction?

Pb + H20 =
Ca + HCl =
Cu + AgNO3 =
Na + H20 =
Cl2 + NaBr =
CuCO3 + heat =
NaOH + heat =
KNO3 + heat =

Thanks in advance

1. Pb is not an inert metal to react with water

2. Ca + 2HCl -> CaCl2 + H2O

3. 2AgNO3 + Cu -> Cu (NO3) 2 + 2 Ag (copper-silver ions displaced had a greater potential for reduction)

4. Na + H2O -> NaOH + H2

5. 2NaBr + Cl2 -> 2 NaCl + Br2 chlorine (gas displaces the bromine ions, because there will be a greater potential reduction - are oxidized metal ions reduced metals, ions)

6. CuCO3 + heat -> CuO + CO2

7. No response will not be watered down, the base (NaOH)

8. 4KNO3 -> 2K2O + 4NO2 + O2
