Can you make water by burning hydrogen gas in air?

Yes. Burning hydrogen gas in air produces water vapor.


Molecular mass equals 2vapour density?

vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass


What is the biggest gas hydrogen helium and water vapor besides oxygen?

The biggest gas among hydrogen, helium, and water vapor, besides oxygen, is water vapor. Water vapor is the gaseous form of water and can exist in significant amounts in the Earth's atmosphere. Hydrogen and helium are lighter gases and typically exist in smaller quantities in the atmosphere compared to water vapor.


What is the primary gas in a volcano?

There are many gases emitted from volcanoes, such as water vapor (yes, it's a gas!), carbon dioxide, and sulphur dioxide. They are also known to release smaller amounts of hydrogen sulfide, hydrogen, carbon monoxide, hydrogen chloride, hydrogen fluoride, and helium into our atmosphere.


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

Is water vapor the same as hydrogen?

No, water vapor is a gas formed when water evaporates, while hydrogen is a colorless, odorless, and tasteless gas. Water vapor is composed of two hydrogen atoms and one oxygen atom, while hydrogen exists as individual hydrogen molecules.

How is a container of hydrogen gas and oxygen gas different form a container of watervapor?

A container of hydrogen gas and oxygen gas contains separate molecules of H2 and O2, while a container of water vapor contains H2O molecules. The hydrogen gas and oxygen gas in the first container can react to form water vapor under certain conditions.

When hydrogen burns what gas is produced?

When hydrogen burns, water vapor (H2O) is produced as a byproduct.


What happens when hydrogen iodide breaks down?

When hydrogen iodide breaks down, it forms hydrogen gas and iodine vapor. The reaction is reversible, meaning that hydrogen iodide can reform if hydrogen gas and iodine are combined.
