1 and 2. only Br2 + 2NaI ---> 2NaBr + I2 not C
3 PCl3 + Cl2 ==> PCl5 : heated
4. 2P + 3Br2 ===> 2PBr3
5. CaH2 + 2H2O ==> Ca(OH)2 + 2H2
6 : H2SO4 + 2K ==> K2SO4 + H2
7. C3H8 + 5O2 ===> 3CO2 + 4H2O
8. 2C6H6 + 15O2 ====> 12CO2 + 6H2O

1. Not possible, you cant form a bromine salt, with a carbon in the reactants.
2. Br2 + 2NaI yields 2NaBr + I2 (single replacement)
3. PCl3 + Cl2 yields PCl5 (combination)
4. 2P + 3Br2 yields 2PBr3 (combination)
5. not possible, need more reactants
6. not possible need more products
7. C3H8 + 5O2 yields 3CO2 + 4H2O (combustion)
8. C6H6 + (15/2)O2 yields 6CO2 + 3H2O (combustion)
