Question

in the balanced equation ( 2h_2 + o_2
ightarrow 2h_2o ), what is the ratio of ( o_2 ) to ( h_2o )?
a. ( 1:2 )
b. ( 2:1 )
c. ( 1:1 )
d. ( 2:2 )

Explanation:

Step1: Analyze the balanced equation

The balanced equation is \(2H_2 + O_2
ightarrow2H_2O\).

Step2: Determine the ratio of \(O_2\) to \(H_2O\)

From the equation, the coefficient of \(O_2\) is \(1\) and the coefficient of \(H_2O\) is \(2\). So the ratio of \(O_2\) to \(H_2O\) is \(1:2\).

Answer:

a. \(1:2\)
