If 0.10 M aqueous solutions are prepared of each of the following acids, which produces the solution with the lowest pH?Group of answer choicesbenzoic acid (HC7H5O2), Ka = 6.3 x 10–5acetic acid (HC2H3O2), Ka = 1.8 x 10–5hydrocyanic acid (HCN), Ka = 4.0 x 10–10hydrogen sulfite ion (HSO3-), Ka = 6.2 x 10–8hypobromous acid (HOBr), Ka = 2.5 x 10–9

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

answersilicon (si); oxygen (o);

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
