In a laboratory demonstration, a balloon filled with methane and oxygen was exposed to a flame. The result was a brief, large flame. The students were asked to formulate an equation for the reaction. One answer is below. (3 points) Is this equation correct? Explain your reasoning.

CH4(g) + 2O2(g) > CO2(g) + 2H2O(g)

Explanation:

Even though the question is incomplete because the equations are missing. However, one thing that is clear from the question is that the reaction is a combustion reaction.

A combustion reaction is a type of reaction that produces heat and light. The mixture of methane and oxygen yielded a brief, large flame which shows that combustion has taken place according to the equation shown above.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
