Chapter 1Study Guide |
1.1 Chemistry
Because living and nonliving things are made of matter, chemistry affects all aspects of life and most natural events.Hint
Chemistry can be divided into five traditional areas of study: organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry.Hint
Pure research can lead directly to an application, but an application can exist before research is done to explain how it works.Hint
Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed citizens.Hint
1.2 Chemistry Far and Wide
Chemists design materials to fit specific needs. Chemists play an essential role in finding ways to conserve energy, produce energy, and store energy.Hint
Chemists supply the medicines, materials, and technology that doctors use to treat patients. Chemists help to develop more productive crops and safer, more effective ways to protect crops.Hint
Chemists help to identify pollutants and prevent pollution.Hint
To study the universe, chemists gather data from afar and analyze matter that is brought back to Earth.Hint
1.3 Thinking Like a Scientist
Alchemists developed tools and techniques for working with chemicals.Hint
Lavoisier helped to transform chemistry from a science of observation to the science of measurement that it is today.Hint
Steps in the scientific method include making observations, testing hypotheses, and developing theories.Hint
When scientists collaborate and communicate, they increase the likelihood of a successful outcome.Hint
1.4 Problem Solving in Chemistry
Effective problem solving always involves developing a plan and then implementing the plan.Hint
The steps for solving a numeric word problem are analyze, calculate, and evaluate. The steps for solving a conceptual problem are analyze and solve.Hint
