1) 2KClO3 >> 2KCl + 3O2
2) C3H8 + 5O2 >> 3CO2 + 4H2O
3) 2Al + 3Fl2 >> 2AlFl3
Hope this answers your question!

1. The basic equation is KClO3 --> O2 + KCl
Start by balancing the oxygen...
2(KClO3) --> 3O2 + KCl
...then match the KCl to the beginning...
2(KClO3) --> 3O2 + 2KCl
2. Basic equation:
C3H8 + O2 --> CO2 + H2O
Get the carbon right first...
C3H8 + O2 --> 3(CO2) + H2O
Now do the hydrogen...
C3H8 + O2 --> 3(CO2) + 4(H2O)
...and finally the oxygen.
C3H8 + 5O2 --> 3(CO2) + 4(H2O)
3. Al is +3, and Fl is -1, so...
Al + F2 --> AlF3
Use two of the product, then balance...
2 Al + 3F2 --> 2AlF3
That's it...hope this helps!

this is simple, but hopefully ull get what im sayin....
1) 2KClO3 ===> 2KCl + 3O2
2) C3H8 + 5O2 ===> 3CO2 + 4H2O
3) 2Al + 3Fl2 ===> 2AlFl3
