Apopulation of purple gorillas feeds entirely on plants. but some of these gorillas are good at digesting plant a, while others are good at digesting plant b. still other purple gorillas are good at digesting plant c. what might be an advantage of a single population of animals, such as the purple gorilla, having a very large amount of variability surrounding certain traits? a. there is no evolutionary advantage to this situation. b. it increases the chance that some members of the population will survive under changing environmental conditions. c. it makes it more difficult for poachers to hunt them. d. it makes it less likely that the population will split into different species, when selective pressures are increased.

What are the variables in gay-lussac’s law? pressure and volume pressure, temperature, and volume pressure and temperature volume, temperature, and moles of gas

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.
