Balance the chemical equation for combustion of propane
Step 1. Insert 1 in front of the most complicated
looking compound ( in this case propane ).
1C3H8 + O2 --> CO2
+ H2O
Step 2. To balance C's, 3 must be inserted in front of
CO2.
1C3H8 + O2 -->
3CO2 + H2O
Step 3. To balance H's, 4 must be inserted in front of
H2O .
1C3H8 + O2 -->
3CO2 + 4H2O
Step 4. To balance O's, 5
must be inserted in front of
O2 .
1C3H8 + 5O2
=
3CO2 + 4H2O
Erase 1 from the equation:
C3H8 + 5O2 = 3CO2
+ 4H2O
The equation is now in balance !
Note: If any fractions should occur, simply multiply the
equation
by a suitable number.
Step 1. Insert chemical equation : C3H8 +
O2 > CO2 + H2O
Step 2. Press Calculate
..... Problem solved !!
