To the original questioneer:
I've tried to split the wording of this question but it's still not understandable:
"How would oxygen be represented in the f--ormula equation for the reaction of methane and oxygen to yield carbon dioxide and water -- A chemical reaction has NOT occurred if the products have -- "
So could the questioneer please rephrase it?

How does the chemical equation show that a chemical reaction occurred?
When a compound produces.
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
What can be used to describe a chemical change?
A chemical equation can be used to describe a chemical change. For instance when iron combines with oxygen to form iron (III) oxide (rust), a chemical change has occurred. It can be written as a chemical formula: 4 Fe + 3 O2 --> 2 Fe2O3
What are the corresponding evidences shown that a chemical change occurred?
chemical change occurred when new chemical substance was created
If the chemical properties of a substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Is substance melts proof that a chemical change has occurred?
no unless there is a chemical change but there isn't. only a physical change has occurred
Are Fizzing or foaming evidence that a chemical change may have occurred?
yes it s an evidence that a chemical change has been occurred
When the chemical composition of rock changes what has occurred?
Chemical change not a physical. A CHEMICAL CHANGE
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
What products in an equation shows that incomplete combustion has occurred?
CO
Does Equality of the accounting equation means that no errors have occurred?
False
