Describe the difference between a covalent bond and an ionic bond.

An ionic bond if formed from the transfer of electrons from the outer shell of atoms. The donor of the electrons becomes positively charged as it has more protons than electrons, and so is called a cation...

Describe the effects of increasing the 1)Pressure 2) Temperature of the following system and what effect this will have on the equilibrium position of this reversible reaction given the forward reaction is exothermic 3H2 + N2 <--> 2NH3

Overall the closed system will behave by Le Chantelier's Principal where the equilibrium moves to minimise change.

So in the first case increasing the pressure will move the equilibrium to the righ...

Experiment results show that butane has a higher boiling point than propane, explain why.

When simple molecular substances such as a hydrocrabons are boiled, the intermolecular forces between the molecules are broken down. Heat energy is required to break down these forces. Butane is larger th...

What is mass spectrometry and how does it work?

In Chemistry we need to know the structures of the molecules we make and work with. We use spectroscopy to work out the shapes of these molecules. Mass spectrometry is one type of spectroscopy and weighs ...
