Iwill mark as brainliest and 20 points the table shows the solubility of two substances in water at 20 °c.

part 1: what will be the values of l and k for 100 kg of each substance?
part 2: explain your answer for part 1.

answer:

i can't understand the table clearly, so i'm solving it with some assumptions i think is closest to what u wanted to say.

in case of sodium chloride;

mass of water = 100 kg

solubility of nacl = 54 g / 100 g of water

thus the mass of nacl needed for full saturation, l = (54/100) x 100 kg = 54 kg

in case of lead nitrate;

mass of water = 200 kg

mass of pbno₃ = 36 kg

if the solution is fully saturated, solubility of pbno₃ (g per 100 g of water)

k = (36/200) x 100 g   = 18 g

k can be also written as 18 kg per 100 kg of water.

thus the difference in k and l = (54-18) = 36.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

the correct answer is b
