The island is 2km. If the scale is 1cm:500m we need to multiply both left and right sides by 4 to get to the 4cm that was measured. This gets us 4cm: 2000m . We now need to convert 2000m to km which gives...

This is because of the strong attractive electrostatic forces holding the oppositely charged ions together and a large number of ionic bonds in the crystal lattice. These require a lot of thermal energy t...

Ionic bonding occurs when a metal and non-metal react together. It involves the metal atom losing electrons from its outer shell to become a positive ion (as there are more positive protons in the nucleus...

Le Chatelier's principle states that is there is a change in concentration, pressure or temperature, the equilibrium will move in order to counteract the change. Firstly temerature - in an reversible reac...

Anerobic respiration is used when AEROBIC respiration can no longer take place. This is because there is a deficit in oxygen so the process of aerobic respitartion can no longer occur. The organism still ...
