As we have learnt

 

Stoichiometry -

Stoichiometry deals with measurements of reactants and products in a chemical reaction.

- wherein

aA (g) + bB (g) → cC (g) + dD (g)

Here, ‘a’ moles of A(g) reacts with ‘b’ moles of B(g) to give ‘c’ mole of C(g) and ‘d’ moles of D(g)

 

 

 

CaCO_{3}\overset{\Delta}{\rightarrow} CaO + CO_{2}

\therefore 1.5 moles of CaCO3 gives 1.5 moles of CO2.


Option 1)
