The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

Chemical Periodicity Gorospe‚ Jheremy Alden B. ____________________________________________________________________________________ ABSTRACT The experiment Chemical Periodicity was demonstrated by using different samples of Group IA‚ Group IIA and Group IVA elements. We placed each of the samples in each test tubes and the physical state‚ color‚ and appearance was identified. We determined the solubility of the elements by using distilled water. We used red and blue litmus paper for the Group

* Chemical Formulas and Reactions . . . Midterm Objectives: * To balance chemical equations. * To interpret chemical reactions. * To understand equilibrium reactions and the factors that can affect them. * Molecular Mass / Formula Mass * Is the sum of the atomic masses of all the atoms present in one molecule of that compound. Example: the molecular mass of sodium bromide‚ NaBr‚ is 103‚ which represents the sum of the atomic mass of sodium (23) plus that of bromide (80)

Period 9 Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement

Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

Economics Discussion Questions 1. Suppose the price of coffee beans increases by $0.20 per pound. What is the effect of this raw material price increase on the demand for roasted coffee? If one pound produces 50 cups of coffee‚ would the price of a cup of coffee rising by $0.01? Explain. Price of the product comes from the production of the goods all the way till it hits the market shelf. So when the price of the product like coffee increases during the productivity of the product then the end

1. Under what environmental conditions are price wars most likely to occur in an industry? What are the implications of price wars for a company? How should a company try to deal with the threat of a price war? Price wars are most likely to occur when the following conditions are present in an industry: the product is a commodity‚ exit barriers are substantial‚ excess capacity exists‚ the industry is consolidated‚ and demand is declining. A price war constitutes a strong threat. It is difficult

Price setting is a key strategy decision. Pricing decisions affects the number of sales and amount of money a company makes. There are many ways to set prices‚ the simplest approaches are demand-oriented and cost-oriented price setting. Demand-oriented price setting approaches consist of Marginal analysis‚ price sensitivity‚ value in use pricing‚ and reference prices. Cost-oriented setting approaches consist of markups‚ Average-cost pricing‚ types of cost‚ and break-even analysis. Some price objectives
