SAT Chemistry The Laboratory - Laboratory Safety Rules

Image
SAT Chemistry The Laboratory -   Laboratory Safety Rules The Ten Commandments of Lab Safety The following is a summary of rules you should be well aware of in your own chemistry lab. Dress appropriately for the lab. Wear safety goggles and a lab apron or coat. Tie back long hair. Do not wear open-toed shoes. Know what safety equipment is available and howto use it. This includes the eyewash fountain, fire blanket, fire extinguisher, and emergency shower. Know the dangers of the chemicals in use, and read labels carefully. Do not taste or sniff chemicals. Dispose of chemicals according to instructions. Use designated disposal sites, and follow the rules. Never return unneeded chemicals to the original containers. Always add acids and bases to water slowly to avoid splattering. This is especially important when using strong acids and bases that can generate significant heat, form steam, and splash out of the container. Never point heating test tubes at yourself or others.

SAT Chemistry Chemical Formulas - Names and Formulas Of Common Acids and Bases

SAT Chemistry Chemical Formulas -  Names and Formulas Of Common Acids and Bases The definition of an acid and a base is expanded later in a first-year chemistry course. For now, common acids are aqueous solutions of hydrogen compounds that contain hydrogen ions, H + . Common bases are aqueous solutions containing hydroxide ions, OH - . A binary acid is named by placing the prefix hydro- in front of the stem or full name of the nonmetallic element, and adding the ending -ic. Examples are hydrochloric acid (HCl) and hydrosulfuric acid (H 2 S). A ternary compound consists of three elements, usually an element and a polyatomic ion. To name the compound, you merely name each component in the order of positive first and negative second. Ternary acids usually contain hydrogen, a nonmetal, and oxygen. Because the amount of oxygen often varies, the name of the most common form of the acid in the series consists of merely the stem of the nonmetal with the ending -ic. The acid containing on

SAT Physics Nuclear Reactions - Radioactive Decay

SAT Physics Nuclear Reactions - Radioactive Decay RADIOACTIVE DECAY Radioactive decay occurs when an unstable isotope spontaneously loses energy by emitting particles from its nucleus. The decay processes were named in their order of discovery by using the first three letters of the Greek alphabet: alpha (α), beta (β), and gamma (γ). After their initial discovery, it was determined that an alpha particle was in fact the nucleus of a helium atom , a beta particle was actually an electron, , and gamma radiation was not a particle at all. Instead, it is a high-frequency photon, . Elements that naturally decay are said to be radioactive. Radioactive substances have a critical imbalance between the number of protons and neutrons in the nucleus. As atoms become larger, more neutrons are needed to maintain stability. Uranium-235 has 92 protons and 143 neutrons. The three common forms of natural radioactivity—alpha, beta, and gamma radiation—are discussed below. Alpha Decay In an alpha
