An atom is made up of 3 sub-atomic particles: the proton, neutron and electron. A proton has a relative mass of 1, a relative charge of +1 and is located in the nucleus. A neutron has a relative mass of 1...

The relative mass of a proton is 1. The relative mass of a neutron is 1. The relative mass of an electron is 1/1840 (accept 0).

(1) First, write out the equation if it is not given: N₂ + 3H₂ ---> 2NH₃ (2) Calculate the moles of nitrogen in the reaction using the information you have; in this cas...

LeChaterlier's principle states: 'If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change'. In short, this helps us to work out HOW cha...

First, let's have a look at all the clues in the name. Aromatic - this type of reaction is characteristic for aromatic compounds because it involves the aromatic ring. It is the only type of electrophilic...
