A silver dollar is flipped twice. Calculate the probability of each of the following occurring: (a) a head on the first flip (b) a tail on the second flip given that the first toss was a head (c) two tails (d) a tail on the first and a head on the second (e) a tail on the first and a head on the second or a head on the first and a tail on the second (f) at least one head on the two flips Susan Williams has been the production manager of Medical Suppliers‚ Inc.‚ for the past 17 years.

12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator will

The Double Helix James Watson accounts all the events of his career that occurred during 1950 to 1953‚ which led to the discovery of structure of the DNA in his famous piece of science writing called “The Double Helix”. In his book‚ James Watson describes how he and Francis Crick discovered the structure of the deoxyribose nucleic acid (DNA) that leads to the major themes of this book‚ which is nature of scientific discovery. Watson describes his and Crick’s search for a simple explanation of DNA

distribution and consumption of goods and services. As a guideline for economics‚ the used of economic indicators are used as a means of predicting or making a forecast about the economy and the different factors that affect those forecast. The purpose of this paper is to identify how the certain economic indicators affect the industry domestically and internationally. The economic indicators to be discussed are the unemployment rate‚ Gross Domestic Product (GDP)‚ interest rates‚ inflation rates

experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were sources of error‚ the hypothesis

Baking Soda Baking Soda‚ also known as sodium bicarbonate or sodium hydrogen bicarbonate is an alkali which is a white crystalline however it often appears as a fine powder‚ its chemical name is NaHCO3. It is used to increase the volume of baked goods. It has a slightly salty‚ alkaline taste resembling that of washing soda (sodium carbonate).

Weak Acid Titration Abstract: Our method for determining the unknown weak acid was to determine the equilibrium constant K from the molecular weight of the weak acid from our titration data. In this lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our ka

Gender based violence/Double victimization One form of gender based violence is sexual assault. Sexual assault is any inappropriate sexual touch by someone who was not given the right to do so. Women are by far more likely to be a victim of sexual assault then a man is. Sexual assault happens all over the world. In the state I live in‚ sexual assault is the second highest crime committed by criminals. There are so many sexual assaults that go unreported. Women fear of retaliation‚ people would

Red Cabbage Indicator Indicators are chemical compounds that can be added to a solution to determine whether it is acidicor alkaline. The indicator will change colour depending on whether an acid or an alkali is added. The colour in red cabbage (it is a pigment called an anthocyanin) makes a very good indicator. Acids and alkalis Acids have a sour taste‚ like vinegar (which contains ethanoic acid) and lemons (which contain citric acid). Alkalis are substances that react with acids and neutralise
