Non metals

Halogens

Group 7 elements that are known for their reactivity.

Group 7

Also known as the halogens, includes elements like fluorine, chlorine, bromine, iodine, and astatine.

Chemical Reaction of Halogens with Hydrogen

Halogens react with hydrogen to form hydrogen halides, which are acids when dissolved in water.

Hydrogen halides

Binary acids formed from hydrogen and halogens, such as HCl, HBr, and HI.

Metal Halide

Compounds formed when halogens react with metals.

Displacement Reaction

A reaction where a more reactive halogen displaces a less reactive halogen from its compound.

Thermal Decomposition

The process by which compounds break down into simpler substances when heated.

Limewater

A solution of calcium hydroxide used to test for carbon dioxide.

Soil Neutralization

The process of increasing the soil pH to neutral using substances like CaCO3 or Ca(OH)2.

Optimum Conditions for Contact Process

Conditions including temperature and pressure that maximize the yield of sulfur trioxide.

Haber Process

A method to synthesize ammonia by combining nitrogen and hydrogen under high temperature and pressure.

Ammonium Nitrate

A chemical compound used as a fertilizer, made from ammonia and nitric acid.
