Document Summary

Use the questions in this guide to review the main concepts. Use your homework and the sample problems on the lecture notes to practice on the quantitative questions and skills. The periodic table lists the elements by increasing atomic number. Zeros after nonzero digits do not count as significant, trailing zeros after a decimal place are significant. Leading zeros before nonzero digits do not count as significant. Cradle-to-cradle recycling: end of usefulness of one product dovetails with the beginning of the life cycle for another product. Atmosphere= a thin layer of gases that surrounds the earth; the diameter of the earth is 7,926 miles. Inhaled air contains: more oxygen used to create energy; less carbon dioxide than . Exhaled air which contains: more carbon dioxide produced as a waste product of energy production; less oxygen as it has been used in respiration. Gas exchange takes place by diffusion in the alveoli within the lungs.
