the reaction of hydrogen and iodine in a closed container to produce hydrogen iodide.

At the start of the reaction, there is a high concentration of hydrogen and iodine, and

thermal decomposition of ammonium chloride to form ammonia and hydrogen chloride.

Ensure that this is conducted in a fume cupboard as ammonia and hydrogen chloride are both

The Hyundai Motors is the first company to mass produce hydrogen fuel cell cars.

we are envisioning a high performance car built on an eco-friendly hydrogen fuel cell.

There's Hydrogen and Helium

The nuclei of two hydrogen atoms join together to form a heavy nucleus of helium.

The nuclei of two hydrogen atoms join together to form a heavy nucleus of helium with the release of a large amount of energy.

Characteristic: Compounds made up of hydrogen and carbon.

Hydrogen plus Nitrogen is equal to Ammonia.

Here, 2 is the subscript of hydrogen and nitrogen.

The negative thermal expansion of water is due to the hydrogen bonds.

Gases like hydrogen are so light that they are escaping through the atmosphere at a rate

but what makes up 90% of us is just 3 elements: oxygen (65%), carbon (18.5%) and hydrogen
