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

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
