1 CHEMICAL REACTIONS

In a chemical reactions atoms are rearranged to produce something new.

Reactants ==> Products

Chemical reactions are also generally difficult to reverse

Chemical reaction
2 Corrosion The production of unwanted products from metals. A coin from Pontius pilate
3 Combustion The burning of a fuel in the presence of oxygen Magnesium burning
4 Precipitation The mixing of two solutions to produce an insoluble solution called a precipitate Lead iodide precipitate
5 Decomposition

A compound breaking down into simpler substances

AB ==> A + B

Elephant toothpaste
6 Hydrochloric acid

An acid which has the chemical formula of HCl

Hydrochloric acid
7 Sulfuric acid

An acid which has the chemical formula of  H2SO4

Sulfuric acid
8 Active metals

An active metal is a metal that reacts with an acid

Examples of active metals are magnesium, zinc and iron.

9 Acid and an alkali(base)

An acid and a alkali neutralise each other to product salt and water.

Acid + Alkali ==> Salt + Water

Note: An alkali is a soluble base

Antacid
10 Acid and an active metal

An acid and an active metal react to produce a salt and hydrogen gas

Acid + Active metal ==> Salt + Hydrogen

11 Acid and a carbonate

A carbonate is a compound that contains the CO3 group.

Carbonates react with acids to produce carbon dioxide gas, water and a salt.

Acid + Carbonate ==> Salt + Water + Carbon dioxide

 

Vinegar and baking soda
