Consider the thermal decomposition of

{LiNO}_3

and

{NaNO}_3

. The volume ratio of

{O}_2({~g})

produced by the thermal decomposition of 4 moles of

{LiNO}_3

and 4 moles of

{NaNO}_3

is respectively

View answer and explanation

Correct option: A

1: 2

Option A (

1: 2

) is correct because lithium nitrate decomposes to lithium oxide, nitrogen dioxide, and oxygen, while sodium nitrate decomposes to sodium nitrite and oxygen. The stoichiometry results in a 1:2 ratio of oxygen produced.
