Determination of the Heat of Formation of Calcium Carbonate Introduction Heat of formation is the enthalpy change when one mole of product is formed from its constituent elements under standard conditions. The equation for the formation of calcium carbonate from its elements under standard conditions is Ca(s)+C (graphite)+O2 (g) CaCO3(s).HfO (CO2 (g)) = -393.5 kJ mol -1 ?HfO (H2O (l)) = -285.5 kJ mol -1 Heat of formation of calcium carbonate = ?H1 + ?Hf (CO2 (g)) +?Hf (H2O (l))- ?H2 = -421+(-393.5)+(-285.5)- (-17.6) = -1082.4 kJ mol -1 In order to achieve the answer, Hess's law is used.

- Ca and Cl are elements and dont have a formula as such. But if your asking what compound they'll form..... calcium is in group 2, meaning is has 2 electrons on its outter …shell and a configuration of [Ar] 4S2, and chlorine is in group 7 so there are 7 out of 8 electrons in the outtermost shell.

- 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 compound from its constituent elements, with all substances in their standard states at 1 atmosphere (1 atm or 101.3 kPa).Its symbol is δ H f or δ f H.he formation reaction is a constant pressure and constant temperature process. Since the pressure of the standard formation reaction is fixed at 1 atm, the standard formation enthalpy or reaction heat is a function of temperature.

It's Elemental Calcium carbonate (CaCO3) is one of the common compounds of calcium. It is heated to form quicklime (CaO) which is then added to water (H2O). This forms another material known as slaked lime (Ca(OH)2) which is an inexpensive base material used throughout the chemical industry. Chalk, marble and limestone are all forms of calcium carbonate. Calcium carbonate is used to make white paint, cleaning powder, toothpaste and stomach antacids, among other things.

Mineral Definition Ch. 2 CaCO3, CaMg(CO3)2. The carbonates contain CO32- as the dominant polyanion in which C4+ is sur rounded by three O2- anions in a planar triangular arrangement. A familiar example is calcite (CaCO3). Because NO3- shares this geometry, the nitrate minerals such as soda niter (nitratite) (NaNO3) are included in this group.
