You will complete eight required core practical activities if you are studying GCSE Chemistry, and 18 if you are studying GCSE Combined Science (five of these are in Chemistry). You could be asked ...

A reaction that puzzled scientists for 50 years has now been explained by researchers at Ume University. Rapid structural snapshots captured how graphite transforms into graphite oxide during ...

We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction ...

The Iodine Clock Reaction is classic chemistry in action. And it is amazingly simple. You can by a kit from a number of different science websites…or you can just go to your local grocery store to ...

The film explains the concept of chemical changes, where two or more materials combine to form entirely different substances. It highlights everyday examples of chemical changes, such as burning wood ...

The importance of reactions between uncharged species (‘neutral–neutral reactions’) has been highlighted in low-temperature environments such as the interstellar medium (ISM) and in the dense ...
