Formal Percent Composition Lab Report Percent Composition is the composition of space given as a percentage. This is the percent composition formula‚ that would help us solve our experiment. Percent composition is important because it shows how much a certain substance is comprised of one component or other Percent composition is used in our everyday life’s. For example if you want to measure how much sugar you have ate. Or how much calories have you gained. Or just how we did in our

Discussion/Conclusion In this experiment‚ t-pentyl chloride was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques

Ideal Temperature for junket Aim- To discover the optimum temperature for junket to solidify Hypothesis- That the optimum temperature will be between 35-40°C Independent variable- Temperature (10‚ 40‚ 60 degrees) Dependant variable- Time taken for Junket to set Control- 2 clearly marker test tubes will be placed under each temperature condition‚ one with junket and one without‚ to clear the complication that it might be the temperature that is reacting with the milk and solidifying it instead

substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with a flame. Let me

extracellular solution‚ this was deemed the baseline. When we punctured each of the DEM‚ DEL1‚ and DEL2 crayfish muscles‚ we observed a large drop in voltage (refer to Figure 1)‚ therefore indicating that inside the muscle was more negative in relation to the outside solution. The time when the pipette was intramuscular‚ the recording showed a steady reading of the intramuscular voltage potential (Figure 1). When the pipette was removed from the crayfish muscle and was back in the extracellular solution‚ the

Sodium: Sodium is essential to all living beings Basic functions: Sodium has 3 main functions: it helps in the absorption of glucose and some amino acids in the small intestine‚ it is required for normal muscle and nerve function‚ and it aids in water balance. Glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium‚ a fact that has exceptionally important implications in medicine. Glucose and galactose are taken into the enterocyte by

In‚ The One Percent Solution‚ by Gordon Lafer‚ he argues that lobbyist groups are taking advantage of the 2008 recession to work to advance the interests of the wealthy. This is being done at the expense of the poor by influencing the policy that government institutions introduce‚ vote on and implement. The lobbyist’s underlying agenda is to try and change the relationship between the workers and the owners as well as shift the expectations for government protections that the workers currently have

2.3 Results 2.3.1 The Effect of O. lybicus Population on Palms Temperature Over Time Temperature differences between different O. lybicus population levels were not significant in leaves and fronds (P > 0.05). However‚ high significance difference in temperature were occurred over time (P < 0.001) in both parts Figure 1 and 2. The temperature at the highest population (1000 insects) were the highest at the first three weeks‚ before it starts declining gradually (figures 14-15). Chlorophyll measurements

will increase the temperature of the ice faster than salts with a smaller density because the heavier salts will sink through the ice faster since they have a heavier density than water and stop the molecules from staying ice faster‚ consequently raising the temperature of the solution‚ than lower density salts would. . The data I collected shows potassium chloride‚ which has a density of 1.98 g/㎤‚ increased the solution’s temperature at a faster rate than any of the other solutions. Using the data

How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process
