Chapter 1: Introduction to Chemistry

Collaboration among scientists decreases the likelihood of a successful outcome.

Which career would require some understanding of chemistry?

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

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

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

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

Who showed that oxygen was a major contribution to chemistry?

A proposed explanation for an observation.

An example of biotechnology would be:

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

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

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

The study of chemicals that do not contain carbon

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

Kinetic Theory states that particles of matter are:

Defined as anything that has mass and occupies space.

Defined as the study of all chemicals containing carbon.

The pursuit of chemical knowlege for its own sake.

What is a hypothesis?

How do conceptual problems differ from numeric problems?

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

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

The scientific method includes:

Research that is directed toward a practical goal or application.

Most elements exist in chemical compounds held together by ________.

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

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

The means by which a society provides its members with those things needed and desired.

Chemical reactions occur when:

The step that usually comes last in solving numeric problems is

The SI unit used to quantify matter.

The variable that is observed during an experiment.

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

Which of the following is FALSE?

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?

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

A representation of an object or and event.

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

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

Chemistry overlaps with all of the other sciences.

When you use your senses to obtain information.

A theory is a

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

One characteristic of a scientific theory is that

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

The study of processes that take place in living organisms.

How many steps are involved in solving numeric problems?

Why do people study chemistry?

Collaboration and communication are important in science because

Every chemical process uses or produces energy.
