The equation shows a --the breaking and forming of chemical bonds that leads to a change in the composition of matter. 2. In the equation, CO2 is a . 3. In the equation, C6H12O6 is a . 4. In O2, the type of bond that holds the two oxygen atoms together is a . 5. In H2O, the type of bond that holds one of the hydrogen atoms to the oxygen atom is a . 6. The number of oxygen atoms on the left side of the equation is the number of oxygen atoms on the right side.

Explanation:

when electronegativity difference is from 0.0 to 0.4 then bond formed between the two atoms is non-polar covalent in nature.

When electronegativity difference is greater than 0.4 and less than 1.8 then bond between the two atoms is a polar covalent bond.

When electronegativity difference is 1.8 or greater than the bond formed is ionic in nature.

According to the given fill ups, the reaction equation is as follows.

   

This means the new products are formed due to the change in chemical composition of the reactants.

Hence, the equation shows a chemical reaction - the breaking and forming of chemical bonds that leads to a change in the composition of matter.And, in the given equation is a product. In the equation, is reactant.In , the type of bond that holds the two oxygen atoms together is a non-polar covalent bond.In , the type of bond that holds one of the hydrogen atoms to the oxygen atom is a polar covalent bond.The number of oxygen atoms on the left side of the equation is equal to the number of oxygen atoms on the right side.
