Background info:
the standard enthalpy of formation (δh∘f) is the enthalpy change that occurs when exactly1 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: substanceδh∘fh(g)218 kj/molh2(g)0 kj/molba(s)0 kj/molba2+(aq)−538.4 kj/molc(g)71 kj/molc(s)0 kj/moln(g)473 kj/molo2(g)0 kj/molo(g)249 kj/mols2(g)129 kj/mol
question:
what is the balanced chemical equation for the reaction used to calculate δh∘f of baco3(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. use (aq) for aqueous solution.
express answer as a chemical equation. explain for me !
