Pre Lab Questions:

1. CaBr2 (aq) + K3PO4 (aq) → CA(PO4)2(S) + KBr (aq) = Ca3(PO4)2 + 6 KBr Double Replacement
2. Li(s) + O2(g) = Li2O(s) =2 Li2O Decomposition

3. CH4 + O2 = CO2 + H2O = CO2 + 2 H2O Combination

4. AgBr(s) = Ag (s) + Br2(l) = 2 Ag + Br2 Combination

5. Mg(s) + H2SO4 (aq) = MgSO4 + H2 Decomposition
