Chapter 1 Review Antoine Lavoisier help to transform chemistry from a science of observation to the science of measurement that it is today. Theories summarize the results of many observations and experiments. A person who succeeds in chemistry does not need to be a good problem solver.
Chapter 1 Review Experiments are used to test hypothesis. Scientists are looking for safer, more effective ways to protect crops. All information on an Internet site is reviewed by qualified scientists. Scientists are always looking for new sources of energy.
Chapter 1 Review A hypothesis may be rejected after an experiment. In a mortar and pestle, the mortar has a bowl-shaped appearance. Ideally, chemicals used to attack insect pests should be nonspecific. All Internet sites that provide scientific information are equally reliable.
Chapter 1 Review The supply of fossil fuels is limited. Theories help you make mental models of objects that cannot be seen. Effective problem solving involves developing a plan, and then implementing that plan. The next questions are short answer.
