Toxicologist use the term LD₅₀ to describe the number of grams of a substance per Kilogram of body weight that is a lethal dose for 50 percent of animals. Calculate the LD₅₀ for a 60Kg man of 2.56 x 10²⁶ molecules of As₂O₃

In which phase(s) do the molecules take the shape of the container?

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
