The main purpose of balancing chemical equations is to make the mass of reactants is equal to mass of products obtained after the reaction. Hence, to make law of conservation of mass is purpose of balancing chemica equations.

p type of semiconductor is obtained when Silicon is doped with a trivalent impurity like Aluminium. Aluminium is a p-type dopant, which means that when a semiconductor i.e. silicon is doped with aluminium, it creates a hole (positively charged carrier) by accepting an electron from the silicon atom. Electrical conductivity of semiconductors increasesand resistivity remains the same
