Question

7. Закінчіть рівняння хімічних реакцій: + 14 O2 = 9 CO2 + 10 H2O = ответ

Answer 1

Balancing Chemical Equation:

To balance the chemical equation, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The given equation is: 14 O2 = 9 CO2 + 10 H2O

Balancing the Equation:

To balance the equation, we can start by balancing the carbon atoms, then the hydrogen atoms, and finally the oxygen atoms.

1. Balancing Carbon Atoms: - There are 9 carbon atoms on the right side (9 CO2). - To balance this, we need 9 carbon dioxide molecules on the left side. - The equation becomes: 14 O2 = 9 CO2 + 10 H2O

2. Balancing Hydrogen Atoms: - There are 20 hydrogen atoms on the right side (10 H2O). - To balance this, we need 10 water molecules on the left side. - The equation becomes: 14 O2 = 9 CO2 + 10 H2O

3. Balancing Oxygen Atoms: - There are 36 oxygen atoms on the right side (9 CO2 + 10 H2O). - To balance this, we need 36 oxygen molecules on the left side. - The equation becomes: 14 O2 = 9 CO2 + 10 H2O

Final Balanced Equation:

After balancing the equation, the final balanced chemical equation is: 14 O2 = 9 CO2 + 10 H2O

This equation represents the balanced chemical reaction.
