Grief is conducting an experiment to see whether goldfish eat more takes or pellots. He thinks that the fish will choose the flakes. Every day, Geoff places both flakes and pellets in a fish tank and observes which food the fish crone. What evidence would be best for Good to collect as he observes the fish?
the time for the fish to finish eating
the number of th that eat each type of food
themes for the shto choose what type of food to eat

Aside from human impact, which of the following causes less water vapor production over a small area? (2 pderivartin

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

Ab c or d ? i’m not sure what the answer is
