The saying "oil and water do not mix" is particularly relevant to the petroleum industry. the most desirable "light crude" has an average density of about 0.82g/ml and thus floats on water. however, some of the more dense "heavy crude" will sink in the water. how dense must crude oil be to sink in water?

Explained

Explanation:

Density of water is 1 g/mL. for any liquid to float on water it's density should be less than water and for sinking in water its density should be more than water.Any other liquid with density less than 1 g/mL will float on the water surface , that is why light crude which has density of 0.82 g/mL floats on water  for crude oil to sink, it's density must be greater than 1 g/mL .

stupid i wont let you get a chance

explanation:

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
