@ ananya 
there is no such tricks are there for remembering reaction , 
on reactions what u have to do is that – just remember the oxidising and reducing species , then remember the reactanat , then u can form the product on your own . 
also learn how to make balance the equation correctly , 
and for give reason ques , u need to know common fact , only then u can answer it . so, try to learn common fact as much as possible .
