The standard enthalpy of formation (ΔH°f) is the enthalpy change that occurs when exactly 1 mol of a compound is formed from its constituent elements under standard conditions. The standard conditions are 1 atm pressure, a temperature of 25 °C, and all the species present at a concentration of 1 M. A "standard enthalpies of formation table" containing ΔH°f values might look something like this:

Substance	ΔH°f
H(g)	218 kJ/mol
H2(g)	0 kJ/mol
Ca(s)	0 kJ/mol
Ca2+(aq)	-543kJ/mol
C(g)	71 kJ/mol
C(s)	0 kJ/mol
N(g)	473 kJ/mol
O2(g)	0 kJ/mol
O(g)	249 kJ/mol
S2(g)	129 kJ/mol

What is the balanced chemical equation for the reaction used to calculate ΔH°f of CaCO3(s)?

If fractional coefficients are required, enter them as a fraction (i.e. 1/3). Indicate the physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively without indicating allotropes. Use (aq) for aqueous solution.

Express your answer as a chemical equation.
