Chapter 1: Introduction To Chemistry
Section 1.1: Chemistry What Is Chemistry? “Chemistry is the study of the composition of matter-the stuff things are made of-and the changes that matter undergoes.” The Five Major Areas of Study 1: Organic Chemistry- the study of essentially all substances containing carbon. 2: Inorganic Chemistry- Substances that do not contain carbon. 3: Analytical Chemistry- Composition of substances 4: Physical Chemistry- theories and experiments that describe the behavior of chemicals. 5: Biochemistry- the study of the chemistry of living organisms.
Section1.2:Chemistry Far And Wide Energy Chemistry is creating new energy conservation methods. Energy-efficient fuels. Sodium lamps used to light up the roads. Plants capture the sun’s energy to create food using photosynthesis.
Section 1.2:Chemistry Far and Wide Medicine And Biotechnology Scientists have the ability to determine the spatial arrangement of atoms in complex biological molecules such as proteins. Substances such as vitamin C, penicillin, and aspirin are created using this.
Section1.2:Chemistry Far And Wide Agriculture Chemistry is used to develop hardier and more productive plants.
Section1.2:Chemistry Far And Wide The Environment Chemists work with Environmentalists to solve problems in the environment with pollutants. Every year the amount of Carbon Dioxide (CO2) in the atmosphere increases and global warming gets worse. The carbon dioxide acts as an isolator of the earth, light rays travel into the atmosphere, reflect back off the earth but the carbon dioxide keeps red light in, which is also heat energy.
Section1.3:Scientific Method Scientific Method- one logical approach to the solution of scientific problems.
Section1.3:Scientific Method Observation-Using you senses to obtain information directly. Hypothesis-proposed explanation or reason for what is observed. Experiment-a means to test a hypothesis. Theory- a broad and extensive tested explanation of why experiments give certain results.
