How to name a salt
The name of a salt starts with the name of the cation (e.g., sodium or ammonium) followed by the name of the anion (e.g., chloride or acetate). Salts are often referred to only by the name of the cation (e.g., sodium salt or ammonium salt) or by the

Properties of transition metals
They form coloured compounds, good conductors of heat and electricity, can be hammered or bent into shape easily, less reactive than alkali metals such as sodium, high melting points (but mercury is aq at room temp), hard and tough, high densities

Process of rusting
Rust is another name for iron oxide, which occurs when iron or an alloy that contains iron, like steel, is exposed to oxygen and moisture for a long period of time.

Calculate concentration
concentration = mass or moles of solute / volume of solution

Calculate relative formula mass
Write the formula of the compound. Write the numbers of each atom in the formula. Insert the relative atomic mass for each type of atom. Calculate the total mass for each element. Add up the total mass for the compound.

how aluminium is extracted from its ore
Aluminium ore is called bauxite. The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted. The extraction is done by electrolysis

simple distillation
First, a liquid is heated, producing a vapor. Then, that vapor is cooled in a small tube called a condenser, in order to form a separate liquid

electrolysis
The process is carried out in an electrolytic cell (q.v.), an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing positively and negatively charged ions.

properties of simple molecules
Low melting and boiling points - This is because the weak intermolecular forces break down easily. Non-conductive - Substances with a simple molecular structure do not conduct electricity. This is because they do not have any free electrons

structures of carbon
Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C60 buckminsterfullerene, e) C540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube.

ionic equations
Start with a balanced molecular equation. Break all soluble strong electrolytes (compounds with (aq) beside them) into their ions. indicate the correct formula and charge of each ion. indicate the correct number of each ion.
