What is the O2 / H2O molar ratio? 2 H2 + O2 ---> 2 H2O

Answer 1

In order to determine the mole ratio, we need to begin with a balanced chemical equation.

For this reaction the balanced chemical equation is
#2H_2 + O_2 -> 2H_2O#

The mole ratios are determined using the coefficients of the substances in the balanced chemical equation.

#2 mol H_2 : 1 mol O_2 : 2 mol H_2O#

The mole ratio for #O_2 / (H_2O)# is:

#2 mol H_2 : 1 mol O_2#

#(2 mol H_2)/ (1 mol O_2)# or #(1 mol O_2)/ (2 mol H_2)#

#1 mol O_2 : 2 mol H_2O#

#(1 mol O_2)/ (2 mol H_2O)# or #(2 mol H_2O)/ (1 mol O_2)#

I hope this was helpful.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
