Question

Write two ways of formation of base.

Answer 1

Answer:

here's your answer

WHEN METAL OXIDE REACTS WITH ACID TO GIVE SALT + WATER

n as we know

base + acid → salt + water

eg-

Mgo+HCl→ MgCl2+H2o

here hcl is acid and MgO is metaloxide

therefore,  it represents that the metal oxide is basic in nature

and also,

metal oxide + water→Base

MgO+H2o→Mg(OH)2

which is base

therefore, when a metal oxide reacts with it forms base
