Question

what do you mean by skeleton equation ​

Answer 1

the unbalanced equation is known as skeleton equation

Answer 2

skeleton equation is a equation which is not balanced.

we know a balanced equation obeys the law of conservation of mass but the skeleton equation doesnot obey the law of conservation of mass.

that it the mass can neither be created nor destroyed.

example

caso4 + hcl  =   h2so4 + cacl2

here the products side and reactant side is not balanced hence it is termed as a skeletal equation.
