FINAL 224 Chapter 3: Economic Crisis & Recovery 1929-1939 Europe in a Depression(1929 till 1932-33) • Origin of the 1929 Downturn - The real origin of the slump had to be located with the US. This does not mean that there were no cyclical weaknesses elsewhere but it is mainly US bcz it had a major influence on the world economy. - The US witnessed 2 major shocks: 1- decrease (Curtailment) of foreign lending 1928-29 which had a deflation impact on

Chemistry - Module 2 - Metal 1. Metals have been extracted and used for many thousands of years * Outline and examine some uses of different metals through history‚ including contemporary uses‚ as uncombined metals or as alloys. Contemporary Uses of common metals Metal | Uses | Iron and Steel (an alloy with <2% carbon)Good tensile strength‚ cheap‚ rusts (corrodes) | - Railways‚ bridges‚ buildings- motor cars bodies‚ ships and trains- Engine blocks‚ fire hydrants‚ drainage

tool for the distribution of information. In school‚ the bulletin board is used to post information for the students. It is essential for the distribution of important information inside the school. Although the traditional bulletin boards are often effective in transmitting information‚ some data may be lost in some instance. Sometimes the pins‚ pastes‚ and tapes are not enough to hold the posters and papers for the bulletin. The bulletin board can be destroyed by naughty students who like vandalisms

BULLETIN BOARDS Based on excerpts from The Expert Educator (Jones‚ et al. ‚ 1994 Description Bulletin boards are either stationary or portable (the latter being handy as room dividers). Most are faced with cork‚ facilitating the attachment of display items. They are often utilized for longterm (more than a few days) display of concepts being emphasized in class. Advantages or Special Purposes 1. Bulletin boards can be used to stimulate learner interest in specified topics of study. 2

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

explore the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it¡¦s state of matter and chemical formula‚ but in the end‚ we will return it to it¡¦s normal solid state. Determine the percentage yield (quantitative). Define what happen at level of electron for oxidation/reduction‚ double replacement‚ neutralization and decomposition. There are five reactions that the copper will go through. 1

Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals

exploitation that forced the hands of the workers to either live free‚ or die trying to gain that freedom. The necessity for the Chilean revolution was not only seen from the bottom up perspective of the workers‚ it also was recognized from the top down‚ by the Salvador Allende government‚ and the people of Chile who voted his Populist Party into power. Faced with the majority of its wealth in the hands of the elite class and foreign investors‚ the workers‚ peasants‚ urban lower class‚ and the indigenous
