A student collected the 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 can measure the freezing point of a liquid that freezes at −80 °C.

B - An alcohol thermometer can measure a wider range of temperatures in a laboratory.

C - An alcohol thermometer is more reliable to measure the temperature of a liquid in a beaker that is 80 °C.

D - An alcohol thermometer is better to measure the boiling points of colorless liquids.

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.
