What is the mole ratio of h2 to O2?

The balanced equation is 2H2 + O2 –> 2 H2O. It takes two hydrogen atoms for every oxygen atom to produce this reaction, so the mole ratio between hydrogen and oxygen is 2:1.

What would the mole ratio be if you were comparing h2s and O2?

The mole ratio between H₂ and H₂O is 2molH₂2molH₂O . 5.00 mol H₂O × 1molO₂2molH₂O = 2.50 mol O₂.

How do you calculate mole ratio?

Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles. There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios.

What type of reaction is 2 H2 1 O2 2 h2o?

synthesis reaction
The chemical reaction 2H2+O2→2H2O 2 H 2 + O 2 → 2 H 2 O is classified as a synthesis reaction.

What is mole ratio?

A common type of stoichiometric relationship is the mole ratio, which relates the amounts in moles of any two substances in a chemical reaction. We can write a mole ratio for a pair of substances by looking at the coefficients in front of each species in the balanced chemical equation.

What is the mole ratio of hydrogen and oxygen gases liberated during electrolysis of water is?

The mole ratio of hydrogen and oxygen gases liberated during the electrolysis of water is 2:1.

When 8 grams 4 moles of h2 react with 2 moles of o2 how many moles of water will be formed?

We have the 4 moles of oxygen but only 4 moles of hydrogen, instead of 8. So, the 4 moles of hydrogen reacts with 2 moles of oxygen, to give 4 moles of water.

What is the molar mass of hydrogen and oxygen in g mol?

The molar masses of hydrogen and oxygen are 2 g/mol and 32 g/mol respectively. The molar ratio of the two gases in the mixture is 50: 12.5 or 4:1. Was this answer helpful?

How do you find the mole ratio in chemistry?

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+O2 → 2H 2O The mole ratios are determined using the coefficients of the substances in the balanced chemical equation.

How many moles are in 8 grams of O2?

One mole of O2 has 32g so 8 grams are equal to 0,25 moles. Now lets set a proportion 2 moles (H2):1 mole (O2)=n:0,25 moles (O2). When you solve a proportion you get n=0,5 moles.
