Question

1. what is the correct coefficient for $h_{2}o$ when balancing the equation $ch_{4}+2o_{2}\to co_{2}+h_{2}o$?

a. 2
b. 3
c. 4
d. 1

Explanation:

Step1: Balance hydrogen atoms

In \(CH_4\), there are 4 hydrogen atoms. In \(H_2O\), let the coefficient be \(x\). So, \(2x = 4\) (from hydrogen balance).

Step2: Solve for \(x\)

Dividing both sides of \(2x = 4\) by 2 gives \(x = 2\).

Answer:

A. 2
