Chapter 1: Introduction to Chemistry

Which step of problem solving identifies the knowns and unknowns of the problem?

The scientific method includes:

A well-tested explanation for a broad set of observations.

The area of study that focuses on the composition of matter.

A logical systematic approach to the solution of a scientific problem.

How many traditional areas of study can chemistry be divided into?

What is a hypothesis?

The study of processes that take place in living organisms.

A proposed explanation for an observation.

Which of the following is FALSE?

Who showed that oxygen was a major contribution to chemistry?

A theory is a

The variable that you change, or manipulate during an experiment.

Collaboration and communication are important in science because

Kinetic Theory states that particles of matter are:

Collaboration among scientists decreases the likelihood of a successful outcome.

The study of the composition of matter and the changes that matter undergoes.

How many steps are involved in solving numeric problems?

Why do people study chemistry?

The variable that is observed during an experiment is called what type of variable?

How do conceptual problems differ from numeric problems?

Defined as anything that has mass and occupies space.

The type of products obtained in a chemical reaction is determined by the reactants' ________.

In which step of problem solving do you determine if your answer makes sense?

Which step in the scientific method requires you to use your senses to obtain information?

Defined as the study of all chemicals containing carbon.

Chemistry overlaps with all of the other sciences.

Which of the following can be observed only in a microscopic view?

An example of biotechnology would be:

Chemical reactions occur when:

The variable that is observed during an experiment.

Which area of study would you use to determine the components of an unknown substance?

The study of the mechanism, rate, & energy transfer that occurs when matter undergoes a change.

The pursuit of chemical knowlege for its own sake.

When scientists say that a theory has never been proved, they are saying that it is unreliable.

One characteristic of a scientific theory is that

When you use your senses to obtain information.

Every chemical process uses or produces energy.

Which career would require some understanding of chemistry?

A representation of an object or and event.

A concise statement that summarizes the results of many observations and experiments.

Who is credited with transforming chemistry from a science of observation to one of measurement

The step that usually comes last in solving numeric problems is

Most elements exist in chemical compounds held together by ________.

Which of these steps should always be followed for effective problem solving?

The study of chemicals that do not contain carbon

The SI unit used to quantify matter.

Defined as the study of chemicals that, in general, do NOT contain carbon.

Which field of science studies the composition and structure of matter?

Research that is directed toward a practical goal or application.
