How many moles of oxygen are produced when 20 moles decomposed?

For every, 2 moles of water, 2 moles of Hydrogen and 1 mole of oxygen are produced. So from 20 moles of water, 10 moles of oxygen will be produced !!!!.

How many moles of oxygen will be produced by the electrolysis?

The correct answer of this question is 5 moles of oxygen gas can be produced during the electrolytic decomposition of 180 g of water.

How many moles of oxygen are produced from 12 moles of water?

6 moles
To produce 12 moles of water 6 moles of oxygen gas are needed.

How many moles of oxygen are in water?

One mole of Water is composed of 1 mole of Oxygen and two moles of Hydrogen.

How many moles of oxygen are in 5 moles of H2O?

Since moles are just “some number of particles”, and since one O2 molecule contains enough oxygen for two H2O molecules, you need 2.5 moles of O2 for 5 moles of H2O.

How does electrolysis produce oxygen?

Polymer Electrolyte Membrane Electrolyzers Water reacts at the anode to form oxygen and positively charged hydrogen ions (protons). The electrons flow through an external circuit and the hydrogen ions selectively move across the PEM to the cathode.

How many moles are in water?

The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.

How many moles of oxygen gas are produced during electrolytic decomposition?

How many moles of oxygen gas can be produced during electrolytic decomposition of 180 g of water? 2 moles (or 2×18 = 36 g) of water gives one mole of oxygen. mol of oxygen= = 5 mol of oxygen.

What is the product of electrolysis of water?

The electrolysis of water causes the decomposition of water, H2O, which produces hydrogen and oxygen gas. The mole ratio of hydrogen to oxygen is 2:1 in the water molecule, and in the products H2 and O2 when water decomposes.

What is the ratio of hydrogen to oxygen in electrolysis?

When water is electrolyzed, hydrogen and oxygen are produced in the ratio 2:1. Why? The mole ratio of hydrogen to oxygen in the water molecule, H2O, is 2:1. When water undergoes electrolysis, it decomposes into hydrogen and oxygen gas in a 2:1 ratio.

How many moles of oxygen does 180g of water produce?

2 moles (or 2×18 = 36 g) of water gives one mole of oxygen. 180 g water will produce 36180 mol of oxygen= = 5 mol of oxygen. Hence, option B is correct.
