Giant ionic lattices don't conduct electricity when they are solids because there arent any free electrons however, when the solids melt, the electrons become free and they can then conduct electricity. Because of this, compounds that are in contact with electricity must have a high melting and boiling point so that they dont conduct electricity.

The higher the number of charges on the ions, the stronger the ionic bond.

giant metalic structures are verry good conductors of both heat and electricity due to their free electrons which can move freely.

One mole of any substance is its relative formula mass, in grams

# data[].attributes.body
= Add up the relative atomic masses of the elements in it, in the ratio shown by it's formula.

The Mole is based on Avogardos number

•6.022 x 10 to the power of 23 particles in one mole

# data[].attributes.body
To work out the number of moles in an atom you need to:

Number of moles = Mass (g) / Relative atomic mass or Mass (g) / relative formula mass

# data[].attributes.body
Step 1: Convert all volumes to dm3

27.5 cm3 = 27.5 ÷ 1000 = 0.0275 dm3

25.0 cm3 = 25.0 ÷ 1000 = 0.025 dm3

Step 2: Calculate the number of moles of the substance where the volume and concentration are known

number of moles = concentration × volume

number of moles of hydrochloric acid = 0.2 × 0.0275 = 0.0055 mol (5.5 × 10–3mol)

Step 3: Calculate the unknown concentration

We can say that 0.0055 mol of acid will react with 0.0055 mol of alkali

concentration of alkali = moles ÷ volume = 0.0055 ÷ 0.025 = 0.22 mol/dm3

How To Use Moles - Part 1 | Chemistry for All | FuseSchool

# data[].attributes.attachment_link.description
Learn the basics about using moles. This is part 1 of 3 parts, teaching you about using moles, as a part of the chemical calculations topic. Avogadro's number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations.

How To Balance Equations - Part 1 | Chemistry for All | FuseSchool

# data[].attributes.attachment_link.description
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms. Chemical reactions can be represented by symbol equations so long as the number of atoms on each side of the equals sign remains the same.

Learn how to carry out titration experiments. In this video, you will learn what apparatus needs to be used to conduct a titration, including pipettes, burettes and conical flasks. Titration experiments enable us to work out the exact concentration of an unknown solute, when we know the concentration of another solute.
