A student collected the data shown in the table below during an experiment. Liquid Characteristics
Liquid Characteristics
Boiling Point Freezing Point Color Toxicity
Mercury 357 °C −39 °C shiny silver gray hazardous if tube is broken
Alcohol 78 °C −115 °C colorless relatively non-hazardous

Based on the data, which of the following conclusions can be made about the use of mercury and alcohol thermometers?

An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C.
A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C.
A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C.
An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
