Question

Write the complete balanced equation for the following reaction:

C4H10 + O2 yields CO2 + H2O

Answer 1

C4H10 from this reaction are reagents and O2, and CO2 and H2O are products.

Now we will calculate the number of atoms on both sides of reagent and product side of the equation.
C4H10+O2→CO2+H2O
C=ll4 atoms on left; l1 atom on right
H=l10 atoms on left; 2 atoms on right
O=lll2 atoms on left; 3 atoms on right

Put 1 in front of C4H10

Now that you've done that you can start to balance the carbon atoms, placing number 4 before CO2.
1C4H10+O2→4CO2+H2O
lC=l4 atoms on left; m4 atoms on right
lH=10 atoms on left; ll2 atoms on right
lO=l2 atoms on left; lll9 atoms on right

Balance H atoms by placing a 5 in front of H2O.
1C4H10+O2→4CO2+5H2O
lC=l4 atoms on left; m4 atoms on right
lH=10 atoms on left; l10 atoms on right
lO=l2 atoms on left; ll13 atoms on right

Now you need to balance the O atoms by putting 6.5 before O2.
1C4H10+6.5O2→4CO2+5H2O
lC=l4 atoms on left; 4 atoms on right
lH = 10 atoms on left; 10 atoms on right
lO =l13 atoms on left; 13 atoms on right

To get rid of the fractions, multiply all coefficients by 2.
2C4H10+13O2→8CO2+10H2O
lC=8 atoms on left; ll8 atoms on right
H=20 atoms on left; 20 atoms on right
O=26 atoms on left; 26 atoms on right

The complete balanced equation for the following reaction C4H10 + O2 yields CO2 + H2O is....

2C4H10+13O2→8CO2+10H2O

Good luck~ Sans

Answer 2

Answer : The balanced chemical reaction will be,

`2C_4H_(10)+13O_2\rightarrow 8CO_2+10H_2O`

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given chemical reaction is,

`C_4H_(10)+O_2\rightarrow CO_2+H_2O`

This reaction is an unbalanced chemical reaction because in this reaction number of carbon, hydrogen and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' is put before the
`C_4H_(10)`, coefficient '13' is put before the
`O_2`, coefficient '8' is put before the
`CO_2` and coefficient '10' is put before the
`H_2O` and we get the balanced chemical equation.

The balanced chemical reaction will be,

`2C_4H_(10)+13O_2\rightarrow 8CO_2+10H_2O`
