Answer :

If 200 g of [tex]KClO_3[/tex] decomposes to produce 135 g of KCl, the amount of oxygen produced should be 65 g.

Law of mass conservation

In every decomposition reaction, the mass of the original substance must be equivalent to the sum of the masses of the products of decomposition.

This is known as the law of mass conservation. If a difference exists between the mass of the decomposing substance and the sum of the masses of the products of its decomposition, then the law of conservation of mass has not been obeyed.

Thus, in the reaction:

[tex]KClO_3 (s) --- > KClO (s) + O_2 (g)[/tex]

Mass of [tex]KClO_3[/tex] = 200 g

Mass of KClO = 135 g

Mass of [tex]KClO_3[/tex] = mass of KClO + mass of [tex]O_2[/tex]

Mass of [tex]O_2[/tex] = mass of [tex]KClO_3[/tex] - mass of KClO

= 200 - 135

= 65 g

Hence, the mass of [tex]O_2[/tex] produced will be 65 g.
