In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

Apart from my curriculum‚ I have a very good leadership and organization skills. I am also a good team player. I had been the House captain of my school and also the organizing committee of my Department in the college and organized National level Symposiums. I also play Tabla and have qualified three grades conducted by Bhatkhande Sangit Vidyapith‚ Lucknow‚ India. I believe that I have all the qualities of a good researcher. I learnt many things from both my victories and failures. Being the team

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

Non-metals will form anions or negative ions‚ since they tend to accept electrons. Activity In this activity you will create models of ionic compounds and observe the chemical formula of the binary molecules you have created. Your data will be recorded in a data table or chart‚ similar to the one below. Cation name Anion name Chemical Formula Name Discussion/Conclusion (talk with your classmates and address in your write-up) Notice the shape and charge of each cation model. Why do

3 February 17‚ 2013 The article‚ “The Sharpe Ratio and the Information Ratio”‚ by Deborah Kidd is about the original risk-adjusted performance measure and they are Sharpe ratio and the Information Ratio. William Sharpe designed the first performance metric to insolate excess return per unit of total risk taken. The Sharpe ratio shows whether a portfolio ’s returns are due to smart investment decisions or a result of excess risk. The Sharpe ratio measure dividends average portfolio excess return
