Using the fоllоwing thermоchemicаl dаtа:2Ho(s) + 6HF(g) → 2HoF3(s) + 3H2(g) ΔrH° = –1787.4 kJ/mol-rxn2Ho(s) + 6HCl(g) → 2HoCl3(s) + 3H2(g) ΔrH° = –1457.0 kJ/mol-rxn Calculate ΔrH° for the following reaction:HoF3(s) + 3HCl(g) → HoCl3(s) + 3HF(g) (Report your answer in units of kJ/mol-rxn, to 1 decimal place, i.e. xxx.x, and no units are necessary in the answer.) (Remember to include a negative sign, if necessary.)
