As part of a class activity, a science teacher blindfolded students and then asked them to touch a 3-D model of a cell. One student felt a thin, flexible layer around the cell. Another student felt an organelle that had the texture of sandpaper. Which organelle did the first student feel? Which organelle did the second student feel?

The thin external covering is similar to the
. The organelle with a texture like sandpaper is the
.

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
