1.1.1 An Introduction to Chemistry

Question 1

An Introduction to Chemistry

Answer 1

• To understand chemistry, it helps to visualize it on an atomic-molecular level.
• Organic molecules behave the same as inorganic molecules.
• Chemistry aids in understanding the world

Question 2

note

Answer 2

• To understand chemistry, it helps to visualize it on an
  atomic-molecular level. Visualizing chemistry on the
  atomic-molecular level helps to explain why and how things happen.
• General chemistry and organic chemistry are often treated as completely separate subjects. However, organic molecules behave the same as inorganic molecules. Their reactivities and structures are based on the same rules as any other molecules.
• Chemistry aids in understanding the world. Chemistry is everywhere—in kitchens, bathrooms, and the streets outside. Understanding the costs and benefits of controversial topics such as nuclear energy requires knowledge of chemistry. This knowledge leads to better informed decisions.

Question 3

Which of the following involves chemistry?

Answer 3

• automobile
• window cleaner
• cooking

Question 4

Which of the following cannot be used to describe the science of chemistry?

Answer 4

• Chemistry is unimportant in everyday life.

Question 5

How can the overlap of chemistry with biology be explained?

Answer 5

• Biological molecules follow the same rules as other molecules, and therefore their study falls into the domains of both biology and chemistry.

Question 6

Which of the following is not a focus of the discipline of chemistry?

Answer 6

• the motion of the planets

Question 7

Which of the following is not influenced by chemistry?

Answer 7

• changing ocean tides

Question 8

Which statement about chemistry is incorrect?

Answer 8

• General chemistry and organic chemistry are completely different sciences.

Question 9

Which statement most accurately describes the discipline of chemistry?

Answer 9

• Chemistry helps us understand the behavior of materials at an atomic or molecular level.

Question 10

How can the relationship between inorganic (general) and organic chemistry best be described?

Answer 10

• Both branches of chemistry share the same central concerns.
