CHEMICAL EQUATIONS, please help!

I am awful at Chemistry! I will appreciate any help!


1. Sodium metal and chlorine react to make sodium chloride.
Ex. Na(s) + Cl2 (g)  NaCl(s)
2. Hydrogen and oxygen combine to form water.

3. Solid iron reacts with gaseous oxygen to form iron (III) oxide.

4. Calcium carbonate decomposes into calcium oxide and carbon dioxide.

5. Lithium oxide and water combine to make lithium hydroxide.

6. Lead (II) nitrate and sodium iodide react to produce lead(II) iodide and sodium nitrate.

7. Nitrogen burns in oxygen to produce nitrogen dioxide.

8. Potassium bromide and chlorine react to form potassium chloride and bromine.

9. Sulfur dioxide and bromine and water react to form hydrogen bromide and sulfuric acid (H2SO4)

10. Aluminum oxide and carbon react to produce carbon dioxide and aluminum.

2Na + Cl2 --> 2NaCl

2H2 + O2 --> 2H2O

4Fe + 3O2 --> 2Fe2O3

CaCO3 --> CaO + CO2

Li2O + H2O --> 2LiOH

Pb(NO3)2 + 2NaI --> PbI2 + 2NaNO3

N2 + 2O2 --> 2NO2

2KBr + Cl2 --> 2KCl + Br2

SO2 + Br2 + 2H2O --> 2HBr + H2SO4

2Al2O3 + 3C --> 4Al + 3CO2

1. Na(s) + Cl2 (g)  NaCl(s)

2. 2.H2 + O2 = 2.H2O

3. 4.Fe(3) + 3.O2 = 2.Fe2O3

4. CaCO3 = CaO + CO2

5. Li2O + H2O = 2.LiOH

6. Pb(NO3)2 + 2.NaI = PbI2 + 2.NaNO3

7. N2 + 2.O2 = 2.NO2

8. 2.KBr + Cl2 = 2.KCl + Br2

9. SO2 + Br2 + 2.H2O = 2.HBr + H2SO4

10. 2. Al2O3 + 3.C = 3.CO2 + 4. Al
