Answer:

1.

S8 + 12 O2 → 8 SO3

This is an oxidation-reduction (redox) reaction:

8 S0 - 48 e- → 8 SVI

8 S0 - 48 e- → 8 SVI(oxidation)

8 S0 - 48 e- → 8 SVI(oxidation)24 O0 + 48 e- → 24 O-II

8 S0 - 48 e- → 8 SVI(oxidation)24 O0 + 48 e- → 24 O-II(reduction)

8 S0 - 48 e- → 8 SVI(oxidation)24 O0 + 48 e- → 24 O-II(reduction)S8 is a reducing agent, O2 is an oxidizing agent

2.

Reactants

ReactantsAl = 3

ReactantsAl = 3Br = 3

ReactantsAl = 3Br = 3K = 2

ReactantsAl = 3Br = 3K = 2S = 1

ReactantsAl = 3Br = 3K = 2S = 1O = 4

ReactantsAl = 3Br = 3K = 2S = 1O = 4Products

ReactantsAl = 3Br = 3K = 2S = 1O = 4ProductsAl = 2

ReactantsAl = 3Br = 3K = 2S = 1O = 4ProductsAl = 2Br = 1

ReactantsAl = 3Br = 3K = 2S = 1O = 4ProductsAl = 2Br = 1K = 1

ReactantsAl = 3Br = 3K = 2S = 1O = 4ProductsAl = 2Br = 1K = 1S = 3

ReactantsAl = 3Br = 3K = 2S = 1O = 4ProductsAl = 2Br = 1K = 1S = 3O = 12

Remember all atoms within the brackets get multiplied by the number outwith them.

Step 1

Put a 6 before KBr

Put a 6 before KBrAlBr3+K2SO4→6KBr+kAl2(SO4)3

Step 2

Put a 2 before

Put a 2 before AlBr3

2AlBr3+K2SO4→6KBr+Al2(SO4)3

Step 3

Put a 3 before

Put a 3 before K2SO4

This balances the Potassium, Sulphur and Oxyen

2AlBr3+3K2SO4→6KBr+Al2(SO4)3

Now check the reactants and products:

Reactants

ReactantsAl - 2

ReactantsAl - 2Br - 6

ReactantsAl - 2Br - 6K - 6

ReactantsAl - 2Br - 6K - 6S - 3

ReactantsAl - 2Br - 6K - 6S - 3O - 12

ReactantsAl - 2Br - 6K - 6S - 3O - 12Products

ReactantsAl - 2Br - 6K - 6S - 3O - 12ProductsAl - 2

ReactantsAl - 2Br - 6K - 6S - 3O - 12ProductsAl - 2Br - 6

ReactantsAl - 2Br - 6K - 6S - 3O - 12ProductsAl - 2Br - 6K - 6

ReactantsAl - 2Br - 6K - 6S - 3O - 12ProductsAl - 2Br - 6K - 6S - 3

ReactantsAl - 2Br - 6K - 6S - 3O - 12ProductsAl - 2Br - 6K - 6S - 3O - 12

3 .

There will be 10 oxygens on the products side and 2 on the reactants so to balance these out, we multiply the 02 on the reactants side by 5. The final equation will be C3H8 + 502 ----> 3CO2 + 4H20.

Sorry, that 2nd answer is too long..cause it was helped by my sister as she also have..so hope it helps you...

Take care...
