Consider the following reaction methane (CH4) combines with oxygen to create carbon dioxide and dihydrogen monoxide. Which of the following would be the coefficient of methane (CH4) in the balanced equation? a. 2
b. 4
c. 5
d. 1
e. 3

I believe it is one. I attached what I think is the balanced equation of the problem you gave. The answer is d.1

Explanation:

CH4+4O=CO2+2H2O

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
