2.(4 pts) Use bond energies listed in Table 10.3 on page 422 of the text book to calculate AH of the following balanced reaction:
2 C2H2(g) + 5 O2(g) → 4 CO2(g) + 2 H2O(g)
Lewis structures without lone pairs: H-C=C-H, O=0,O=C=0, H-0-H

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
