Arrange the compounds in order of decreasing solubility in water. a) butane

b) ethyl methyl ether

c) propanol

Answer by ordering the letters a-c as a string, e. g. acb, starting with the compound of highest solubility.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
