write balanced equation for the thermal decomposition of this few nitrates & carbonates.?

Question

this is an experiment on heating the nitartes and carbonates of the s-block element.
a)lithium nitrates and lithium carbonate
b)potassium nitrates and potassium carbonate
c)magnesium nitrates and magnesium carbonate

Answer 1

LiNO3 gives Li2O, NO2 and O2
Li2CO3 gives Li2O and CO2

KNO3 gives KNO2 and O2
K2CO3 doesn't decompose on normal heating

Mg(NO3)2 gives MgO, NO2 and O2
MgCO3 gives MgO and CO2

Now you can work out the equations yourself.

Answer 2

Thermal Decomposition Of Carbonates

Answer 3

2LiNO3 -------> Li2O + 2NO2+ O2
