i hope this helps<33 :)))))
The answers that are correct are a, b, and d
Answer:
True => ΔH°f for C₆H₆ = 49 Kj/mole
Explanation:
See Thermodynamic Properties Table in appendix of most college level general chemistry texts. The values shown are for the standard heat of formation of substances at 25°C. The Standard Heat of Formation of a substance - by definition - is the amount of heat energy gained or lost on formation of the substance from its basic elements in their standard state. C₆H₆(l) is formed from Carbon and Hydrogen in their basic standard states. All elements in their basic standard states have ΔH°f values equal to zero Kj/mole.
Greatest is at W because kendrick is still and it’s at the highest point.. x has greatest gravitational because it’s closest to the ground.. potential energy is at Z because it’s going straight so it’s stil moving
