What is the word equation for hydrogen and oxygen?

2H2(g) + O2(g) → 2H2O(l ) Chemical equations give the following information about chemical reactions.

What is the word equation for the reaction that forms water from oxygen and hydrogen?

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

What is the balanced equation for the reaction between hydrogen and oxygen?

This reaction may be represented by the chemical equation 2H2+O2→2H2O. The formula weight of hydrogen gas is 2.01594, that of oxygen gas 31.9998, and that of water 18.01534.

What is the word equation for when hydrogen burns in air?

2H2(g)+O2(g)→2H2O(l) .

How do you write hydrogen peroxide formula?

H2O2
Hydrogen peroxide/Formula

What is the symbol for oxygen gas?

O
Oxygen/Symbol

What is 2H2O in chemistry?

Heavy water (2H2O) The number 2 indicates that there are two atoms of hydrogen in a molecule of water. There is also one atom of oxygen but the number one is omitted from a chemical formula. Water molecule (formally known as dihydrogen monoxide) is composed of two hydrogen atoms and one oxygen atom.

Which of the following represents the word equation of formation of water?

Answer: 2H2(g)+O2(g)⟶2H2O(l) is the correction reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.

What is the combination of hydrogen and oxygen?

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right.

What happens when hydrogen burns in air?

Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2. In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy. The energy released enables hydrogen to act as a fuel.

What is chemical equation of hydrogen gas?

Therefore, the molecular formula of Hydrogen gas can be determined by observing the hydrogen atoms. Normally, a pair of hydrogen atoms are found bonded together into molecules….Hydrogen Gas Chemical Formula.

What is the symbol for hydrogen peroxide?

What is the overall reaction in a hydrogen oxygen fuel cell?

The overall reaction in a hydrogen-oxygen fuel cell is: hydrogen + oxygen → water 2H2(g) + O2(g) → 2H2O (l) Electrode half equations – Higher

What is a chemical word equation give an example?

A chemical word equation is when you use the symbols from the Periodic table together to make a new substance. ex. H2O Hydrogen + 2 Oxygens = Water OR H + O2 = H2O (H-hydrogen O-oxygen H2O- water) Thats a chemical word equation! What does this mean water hydrogen plus oxygen?

What is the chemical equation for hydrogen to water vapor?

The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus oxygen gas produces water. 2H2 + O2 –> 2H2O

What is the chemical equation for francium hydroxide hydrogen gas?

Francium is a very rare metal that would oxidize very quickly. The word equation is francium + oxygen -> francium hydroxide + hydrogen gas. What is the balanced symbol equation for hydrogen and oxygen?
