I did a workshop and am having a few problems understanding three of the questions.
When Benzene, is burned in excess of oxygen
my teacher gave us the answers
2C6H6 + 150--> 6H2O+CO2
A piece of rubidium is dropped in water., a violent reaction occurs
2RB+H2O-->2RbOH + H2
why can't you just write RbH2O: referring to reactant side?
A solution of ammonia is mixed with a solution of sulfric acid
Why does it change to ammonium on the reactant side with a subscript of 2?
