For a given reaction, it is often seen that the rate of reaction doubles following a 10oC increase in temperature. But why is this?

(note: Here I would plot a graph of Rate vs Temperature, to show ...

Atomic Number: Number of Protons in the nucleus of the atom, also equal to the number of electrons in a neutral atom.

Mass Number: Total number of "nucleons" (Protons and Neutrons) in the...

As you move from group 1 across the periodic table to group 7.

1. The types of bonding change. Consider an element within group 1 - Lithium (Li). This exists as a metal, it has metallic bonding....

Catalyst are chemical or biological substances that speeds up the rate of reaction without being used up in the overall process. It provides an alternative route for a reaction occur with a lower activati...

THe potassium would move around on the water and fizz. This is because it is an alkali metal that reacts with the water. 2K + 2H2O --> 2KOH + H2. The fizzing is the result of this reaction. Discussion ...
