Rite an equation for the formation one mole of CaCO3(s) from its elements in their standard states. Write any reference to carbon as C(s). Express your answer as a chemical equation using fractional coefficients as needed. Identify all of the phases in your answer.

The chemical equation for the formation one mole of from its elements in their standard states is

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 from its elements in their standard states is:

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

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
