Question

_____ C7H16 + _____ O2 → _____ H2O + _____ CO2Balancing Equations problem. Thanks

Answer 1

in1) Balance the chemical equation.

`C_{7_{}}H_(16)+O_2\rightarrow H_2O+CO_2`

Balance carbons

Seven carbons in the reactants and one in the products. Write 7 in front of CO2

`C_7H_(16)+O_2\rightarrow H_2O+7CO_2`

Balance Hydrogens

Sixteen hydrogens in the reactants and two in the products. Write eight in front of H2O.

`C_7H_(16)+O_2\rightarrow8H_2O+7CO_2`

Balance Oxygens

Two oxygens in the reactants and twenty-two in the products. Write eleven on front of O2.

`C_7+11O_2\rightarrow8H_2O+7CO_2`
