## What happens when hydrogen reacts with 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 is the equation for oxygen?

The chemical symbol for oxygen is O, but pure oxygen exists as diatomic (“two-atom”) molecules, represented by the chemical formula O2.

## Does hydrogen explode in air?

Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.

## Can you make water from oxygen and hydrogen?

Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result in a rather large explosion.

## Is C o2 co2 a balanced equation?

You may need to multiply both sides if the number of an atom on the right is not a multiple of the atoms on the left.Example.

Step Result Equation balanced?
1 carbon monoxide + oxygen → carbon dioxide
2 CO + O 2 → CO 2
3 Reactants: 1 × C, (1 × O) + (2 × O) = 3 × O. Products: 1 × C, 2 × O Not balanced.
4 2CO + O 2 → CO 2

## Is h2 o2 h2o a balanced equation?

The equation is now balanced.

O

## What is skeleton equation?

A skeleton equation is when your chemical reaction is written with the chemical formulas that represent each substance that takes part in the reaction. Examples: The word equation: Methane + Oxygen. Carbon dioxide + Water.

## Why is it called h2o?

The scientific name for water is H2O. It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O). When water boils, water molecules move very fast. Water molecules move so fast that they actually break apart from each other and escape into the air as water vapor or steam.

## What type of reaction is h2 o2 → h2o?

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

## Can hydrogen gas kill you?

Pure hydrogen will not kill you. A lack of oxygen will kill you. A lack of oxygen will kill you. Breathing pure hydrogen has the same effect as breathing pure helium: a lungful will do nothing worse than make your voice higher-pitched, but a few lungfuls will asphyxiate you from lack of oxygen.

## What are the dangers of hydrogen?

Physical dangers: The gas mixes well with air, explosive mixtures are easily formed. The gas is lighter than air. Chemical dangers: Heating may cause violent combustion or explosion. Reacts violently with air, oxygen, halogens and strong oxidants causing fire and explosion hazard.

#### Bonding energy equation

What is bond energy in chemistry? In chemistry, bond energy (BE), also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond. The larger the average bond energy, per electron-pair bond, of a molecule, the more stable and lower-energy the molecule. What are the units of […]
