Four elements‚ hydrogen‚ carbon‚ oxygen and nitrogen‚ are the major components of most organic compounds. Consequently‚ our understanding of organic chemistry must have‚ as a foundation‚ an appreciation of the electronic structure and properties of these elements. The truncated periodic table shown above provides the orbital electronic structure for the first eighteen elements (hydrogen through argon). According to the Aufbau principle‚ the electrons of an atom occupy quantum levels or orbitals starting

Psychology- study of the human mind or animal behavior. History: Psyche: “soul/mind” Logos: “study” *Behaviorists are interested in overt behavior *cognitivists: believes not all behaviors are seen. Eras: -Traditional -superstitions -Ancient Greek Philosopher’s Period- assumptions that are not verified from reality. (Socrates‚Plato‚Aristotle‚Democritus‚Galen) -Medieval Period(St. Thomas‚St. Augustine) -Pre-Modern- Psychology is not yet a science. -Modern- Wilhelm Wundt(1879) – father

Unit 8 Textbook Notes 12.1 The N2O4-NO2 Equilibrium System When you put a sample of N2O4‚ a colorless gas‚ in a closed container at 100C a reddish-brown color starts to show. This is due to NO2 formed by the decomp. of part of the original substance. The forward and reverse reactions are taking place at the same rate. The concentrations of species present remain constant with time. These concentrations are independent of the direction from which equilibrium is approached. The equilibrium constant

Chemistry • Element – pure substances that cannot be broken down into simpler substances. Made up of particles/atom of only one kind. Simplest pure substances. • Compounds – pure substances which contain two or more different elements. • Atom – smallest particle of an element. The smallest unit of an element that maintains the properties of that element. • Chemical Group – the set of elements in the same column of the periodic table. These elements have similar physical and chemical properties

Topic 1 The nature of economics The economic problem: The economic problem is that our wants are unlimited and our means of satisfying these wants (resources) are limited. What to produce? Decide which wants are most important to consumers How much to produce? Allocate resources efficiently to maximise satisfaction of wants How to produce? An economy must allocate resources in the production process. It must look for the most efficient method of production that uses the least amount of resources

of ions‚ ionic compounds are electrically neutral. Most ionic compounds are crystalline solids at room temperature. Ionic compounds generally have high melting points. Ionic compounds can conduct an electric current when melted or dissolved in water. 7.3-Bonding in Metals The valence electrons of metal atoms can be modeled as a sea of electrons. Metal atoms are arranged in very compact and orderly patterns. Alloys are important because their properties are often superior to those of their

dig limestone out of the ground in quarries Its main use is as a building material/ in the manufacture of iron Powdered limestone + high temperature+ sand+ sodium carbonate= glass powdered limestone + powdered clay + heat= cement cement powder + water + sand +gravel= concrete Limestone + strong heating= quicklime (calcium oxide) + carbon dioxide (thermal decomposition) To make lots of quicklime we use a lime kiln 1) fill the kiln with crushed limestone 2) heat it strongly with a supply of hot air quicklime
