How much heat is released or absorbed (in kJ) by the system in the reaction of 17.7 g of SF6 with 23.7 g of H2O?
Make sure to enter the correct sign (+ or -). Enter to 2 decimal places. SF6 (g) + 3 H2O (l) \longrightarrow⟶ 6 HF (g) + SO3 (g) \DeltaΔHf° (kJ/mol) -1209 -285.8 -271 -395.6

+279.744 kJ.

Below is an attachment containing the solution to question.

what's the

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.
