Question

LAW OF CONSERVATION OF MASS
What is Li2SO3 + BF3 -> B2(SO3)3 + LiF

Answer 1

The given reaction does not follow law of conservation of mass .

The Balanced reaction which follow law of conservation of mass is :

`3Li_(2)SO_(3) + 2BF_(3)\rightarrow B_(2)(SO_(3))_(3) + 6LiF`

Step-by-step explanation:

LAW OF CONSERVATION OF MASS : Mass can neither created nor destroyed in a chemical reaction.

So, total number of atoms present in reactant should be equal to total number of elements present in the product.

`3Li_(2)SO_(3) + 2BF_(3)\rightarrow B_(2)(SO_(3))_(3) + 6LiF`

Here ,

total number of atoms present in reactant = total number of elements present in the product.

Li = 6

B = 2

F = 6

S = 3

O = 9
