Electrophilic aromatic substitution (SEAr) is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by ...
An Atom is made up of 3 parts, protons, neutrons and electrons. Each element has it's own number of protons and electrons<...
concentration = moles / volume
must convert volume into litres 1 litre = 1000cm3 (divide by 1000)
c= n/v = 0.4/0.025 = 16mol/l
At dynamic equilibrium in a closed system (for example, in the Haber process to make ammonia), both the forward and backward reactions continue to occur. However, both reactions happen at the same rate...
