rite an equation for the formation one mole of CaCO3(s) from its elements in their standard states. Write any reference to carbo
maks197457 [2]

Answer: The chemical equation for the formation one mole of CaCO3(s) from its elements in their standard states is Ca(s)+C(s)+\frac{3}{2}O_2(g)\rightarrow CaCO_3(s)

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 CaCO3(s) from its elements in their standard states is:

Ca(s)+C(s)+\frac{3}{2}O_2(g)\rightarrow CaCO_3(s)

where (s) represents solid state and (g) represents gaseous state.
