The percent yield was calculated to be 171% indicating a source of error. The high percent yield was due to the product being wet since we did not have enough time to dry the product with the vacuum filter—since we had to evacuate the building due to the fire alarm. If we were able to vacuum filter our product more‚ the percent yield would be close to 100%. 1. Assign the peaks in your NMR spectrum of your salicylic acid. See NMR spectrum on back 2.

The percent yield of meso-1‚2-dibromo-1‚2-diphenylethane was calculated to be 66.36% and with a melting point of 235.1°C. Therefore‚ it can be concluded that this experiment was successfully conducted as the percent yield obtained is only 33.64% off from the equilibrium point‚ and because the melting point met the literature value. The percent yield for the product was less than 100%‚ indicating that were experimental errors‚ such as an undesirable side reaction‚ or more likely‚ an incomplete reaction

World’s Reliance on Computers By; Kevin Roach Jr. April 26th 2011 Computers are used in many different ways; they are used in all sorts of different fields of work and are very important to many different people. Practically anything that you use is made by computers. Today’s modern vehicles and airplanes were are designed on a computer. Our country’s traffic signals are run by a network of computers. In a hospital‚ most lifesaving machines are run by computers. Space exploration would not

Professor Jim Riley MGMT 3614-01 Case for Analysis: Intel Prepares Its Top Leaders In spring of 2005‚ Paul Otellini became the new CEO of the Intel. In fact‚ according to the article‚ Otellini is the fifth homegrown CEO to run the Intel since its launch in 1968‚ which suggests that there’s an “Intel inside” aspect to its management formulas as well as its high-performance chips. To recruit the CEO from the inside seems to work well for Intel‚ and actually it is a sound policy. First at all‚ recruiting

INTRODUCTION The 8086 microprocessor is the 16 bit microprocessor which means that the arithmetic logic unit‚ its internal registers and also the data bus these entire have to work with 16 bit at a time. The microprocessor has 20 bit address bus and therefore 220 memory locations. The pin diagram of 8086 is as shown: The 8086 microprocessor is just like 8085

4.4ai. The price elasticity of demand is given to calculate the new price. The fruit stall has 100 peaches initially but 10 peaches are rotten. It means the number of remaining peaches is 90 units. Therefore‚ the question provides the factors such as initial quantity‚ new quantity‚ initial price which are 100‚ 90‚ 1 respectively. Let the new price be x. Therefore‚ we will choose $1.2 per unit as the new price to sell the remaining peaches. 4.4aii. Case 1: If I do not discover the
