Astudent collected data shown in the table below during an experiment. based on the data, which of the following conclusions can be made about the use of mercury and alcohol thermometers
a) an alcohol thermometer is more appropriate than mercury thermometer to measure the boiling point of a colorless liquid that boils at 100°c
b) a mercury thermometer is more appropriate than an alcohol thermometer to measure the boiling point of a colorless liquid that boils at 82°c
c) a mercury thermometer is more appropriate than alcohol thermometer to measure the freezing point of a colorless liquid that freezes at -40°c
d) an alcohol thermometer is more appropriate than mercury thermometer to measure the freezing point of a colorless liquid that freezes at -20°c

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull
