Question 1

How would you describe the volume of the following object? the amount of water in a swimming pool

Accepted Answer

The volume of water in a swimming pool is macroscopic, meaning it is large enough to be visible and measurable on a human scale. The other options (microscopic and submicroscopic) refer to objects or particles that are too small to be seen by the naked eye or even with a microscope, which is not applicable to the volume of water in a swimming pool.

Question 2

A biological cell is best described as ________.

Accepted Answer

Biological cells are too small to be seen with the naked eye and require a microscope for visualization. Therefore, they are described as microscopic rather than macroscopic or submicroscopic. While cells are small, nanoscopic is not a commonly used term to describe their size.

Question 3

According to John Dalton, atoms of a given element ________.

Accepted Answer

According to Dalton's atomic theory, atoms of a given element are identical in their properties such as mass and chemical behavior.

Question 4

Alchemist of the Middle Ages believed that ________.

Accepted Answer

Alchemists of the Middle Ages were notorious for their obsessive search for a way to transform base metals into gold. They believed that the basic qualities of a substance, such as its color or texture, could be altered through various chemical processes to produce a more valuable product. This belief in transmutation was a cornerstone of alchemical philosophy, and many alchemists spent their entire lives searching for the elusive Philosopher's Stone, a substance said to be capable of transforming any metal into gold.

Question 5

How would you describe the size of the following object? a blood cell

Accepted Answer

A blood cell is too small to be seen with the naked eye and requires magnification to be observed. Therefore, it is considered microscopic.

Question 6

How does Aristotle's model of matter explain how a puddle of water disappears to dryness on a sunny day?

Accepted Answer

According to Aristotle's model of matter, water is a combination of the elements of water and earth. When water is heated by the sun, the element of heat combines with the element of water to produce air, which evaporates the water and causes it to disappear. Therefore, option B is the correct choice.

Question 7

According to Aristotle's hypothesis about matter, wet clay is converted to ceramic because ________.

Accepted Answer

According to Aristotle's hypothesis about matter, wet clay is converted into ceramic because fire replaces the moist element with the dry element.

Question 8

How does Aristotle's model of matter explain why the air over a flame is always moist?

Accepted Answer

The answer of How does Aristotle's model of matter explain...

Question 9

The same amount of red colored Kool-Aid crystals are added to a still glass of thick sugar water and a still glass of distilled water. Both are the same temperature. Neither is stirred. Which should become uniform in color first?

Accepted Answer

Distilled water has no impurities, so the Kool-Aid crystals will dissolve faster and distribute evenly throughout the water, resulting in a uniform color sooner than in the thick sugar water. The sugar in the thick sugar water may slow down the dissolution process and make it harder for the Kool-Aid crystals to evenly distribute.

Question 10

Considering how small atoms are, what are the chances that at least one of the atoms exhaled in your first breath will be in your last breath?

Accepted Answer

The chances are very probable because atoms are incredibly small and can last for millions or even billions of years. It is possible that at least one of the original atoms from your first breath is still present in your last breath.

Question 11

In what sense can you truthfully say that you are a part of every person around you?

Accepted Answer

We are made up of atoms and constantly exchanging them with the environment and those around us. Therefore, we are technically a part of every person around us in a physical sense. However, this does not mean we share the same genetic code or that there are more people alive now than have ever lived. A is partially true but not specific enough to answer the question.

Question 12

Aristotle described the composition and behavior of matter ________.

Accepted Answer

Aristotle believed that matter was composed of the 4 qualities or properties of hot, cold, moist and dry, which were responsible for the behavior of matter. He did not describe matter as the elements of fire, water, air and earth nor did he believe that it was unchanging or simply states of perception.

Question 13

Dmitri Mendeleev's chart of elements ________.

Accepted Answer

Mendeleev's chart of elements placed elements together with similar properties, creating the periodic table as we know it today. It also allowed for the prediction of unknown elements and their properties, further contributing to the organization of the elements. While there were gaps in the chart at the time, Mendeleev's predictions eventually proved to be accurate.

Question 14

Red colored Kool-Aid crystals are added to a still glass of hot water. The same amount of crystals are added to a second still glass filled with the same amount of cold water. With no stirring, which of the following would occur?

Accepted Answer

The higher kinetic energy of the hot water will cause the molecules to move faster and distribute the dye more quickly, resulting in a faster uniform color.

Question 15

Based on the Law of Mass Conservation, Lavoisier hypothesized that ________.

Accepted Answer

Lavoisier's hypothesis that an element is made of a fundamental substance that cannot be broken down into anything else is based on the Law of Mass Conservation, which states that matter cannot be created or destroyed in an isolated system.

Question 16

You take 50 mL of small BB's and combine them with  of large BB's and you get a total of 90 mL of BB's of mixed size. Which of the following statements best explains this?

Accepted Answer

The answer of You take 50 mL of small BB's...

Question 17

Dmitri Mendeleev ________.

Accepted Answer

Mendeleev is known for all three of these contributions to the field of chemistry. He arranged the known elements into a table based on their properties and predicted the existence of undiscovered elements based on the pattern he observed in the table. This led to the discovery of several new elements and confirmed the validity of his table. Mendeleev's table is the basis for the modern periodic table of elements.

Question 18

Based on experimental evidence, John Dalton postulated that ________.

Accepted Answer

John Dalton's postulate that each element consists of indivisible, minute particles called atoms is based on experimental evidence and is one of the fundamental principles of modern chemistry. His other postulates did not hold up under further experimental testing.

Question 19

A TV screen looked at from a distance appears as a smooth continuous flow of images. Up close, however, we see this is an illusion. What really exists are a series of tiny dots (pixels). This is similar to a chemist's view of matter in that ________.

Accepted Answer

This choice directly relates to the analogy presented in the question, where the TV screen appearing continuous from a distance is akin to matter appearing continuous to the naked eye, but being composed of small particles (atoms and molecules) when examined on a submicroscopic level.

Question 20

Dalton's atomic model gained credibility because ________.

Accepted Answer

Dalton's atomic model was able to explain much about known chemical reactions, which gave it credibility. The other options are not relevant to the credibility of his model.
