Chemical Equations

You MUST have correct equations when balancing Chemical Equations !

For Example:

Lead (IV) Nitrate = Pb(NO3)2

Copper (II) Chloride = CuCl2

2Mg (s) + 1O2 (g) → 2MgO (s)

^ REACTANTS ^ ^ FORMS ^ PRODUCTS
Examples:

1) 4 K + O2 → 2 K2O

2) N2 + 2 H3 → 2 NH3

3) 2 Al + 3 Cl2 → 2 AlCl3

4) 2 AlBr3 + 3 SrCO3 → Al(CO3)3 + 3 SrBr2

5) Fe2O3 + 3 H2SO4 → Fe2(SO4)3 + 3 H2O

6) Ca(OH)2 + 2 NH4Cl → 2NH3 + CaCl2 +2 H2O
