Answer: The chemical equation for the formation one mole of [tex]CaCO3(s)[/tex] from its elements in their standard states is [tex]Ca(s)+C(s)+\frac{3}{2}O_2(g)\rightarrow CaCO_3(s)[/tex]
Explanation:
The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.
The chemical equation for the formation one mole of [tex]CaCO3(s)[/tex] from its elements in their standard states is:
[tex]Ca(s)+C(s)+\frac{3}{2}O_2(g)\rightarrow CaCO_3(s)[/tex]
where (s) represents solid state and (g) represents gaseous state.
