Q
In order to make ammonium nitrate how would school and industry differ
A
school labs would use dilute nitric acid and ammonia so they are safe

in industry ammonia will be a gas and nitric acid will be concentrated –> very exothermic reaction
2
Q

A
school uses lots of heat from bunsen to evaporate
WHEREAS
industry uses heat from previous exothermic reaction of ammonia and nitric acid
3
Q
