Which is the best example of the law of conservation of energy? O A basketball stops bouncing because its energy disappears.
O A rolling skateboard slows down because some of its kinetic energy changes to heat.
O A falling book hits the ground and all of its energy is destroyed.
O A toy car gains speed as it moves down a ramp because the ramp creates energy.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
