The Incredible Egg The purpose of this lab was to find out what would happen over time to weight of an egg after we scrubbed the eggshell off in a little spot. We then soaked it in water for 10 minutes, 30 minutes, 24 hours and measure how much the weight went up. Once we came back the next day we measured them after 24 hours. In the same day we put the syrup in the cup instead of water and we measured how much it weighed after 10 minutes, 30 minutes and 24 hours. As we did this with the water the weight of the egg went up because the water soaked into the egg and made it heavier.
The absorbance was measured of three different colored substances. Additionally, after determining the absorbance of the different colors, the experiment will use the absorbance to calculate the concentration of dye in beverages. Through Beer’s
A concentrate b. A supersaturated solution d. an extraordinarily saturated solution 5. Which of the following is the best way to prepare a 1 molar, 1 liter,
Volume Lab In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects. Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average was calculated which was 16.6 drops, which meant on average that's how much it needed to make one mL. By subtracting from the average with the hypothesis the hypothesis was revealed to be 6.6 drops off. Part B questions were based on water displacement. In which the question was how much was the difference between 20 mL of water and 3 marbles.
You just got home from a long day at the beach, and all you want is a refreshing drink to cap off the day. You look inside the fridge, and find nothing appealing to you. Then you remember about the packet of Fruit Punch Kool-Aid in the drawer. This small pouch is incredibly affordable for the pitcher it can fill. It showed the world that by mass production and an affordable price, their product can be owned by anyone.
The volume of ethanol in the first vial was .4 mL. The density was .86 grams/mol. The concentration was 72.5%. The weight of the second tared vial was 3.599 grams. The mass of
Introduction The purpose of this lab was to compare simple distillations of two sets of liquids by graphing the boiling points. One set of simple distillation of two liquids were supposed to have a boiling point difference of bout 30C while the other set of simple distillations had a melting point difference of about 57C. Furthermore, by conducting this experiment, students would develop a better understand of distillation and gas chromatography. Furthermore, I hypothesized that cyclohexane and p-xylene distill better than cyclohexane and toluene since cyclohexane and p-xylene have a larger boiling point difference than cyclohexane and toluene. The boiling point of cyclohexane is 80.74C while the boiling point for p-xylene is 138.23C and the boiling point for toluene is 110.6, thus
The water level decreased when the raisins absorbed it. Before the raisins were put in, the water level was 50mL. After the raisins sat in the water for 20 minutes and then taken out, the water level was 47mL. The water level decreased
The volumetric flask was then filled up to its 100 mL mark with deionized water. The buret was washed out with dionized water and then with the strong base NaOH before being filled up with NaOH. About 20 mL of the unknown weak acid was pipetted into a beaker. The starting volume of the NaOH in the buret was recorded before about 4 mL of the strong base was titrated into the weak acid solution. The final volume was recorded.
Carly Herrin American counterculture of the 1960s was one of the most powerful movements that had a lasting influence on American society in the following decades. The counterculture movement is strongly associated with the hippies, sexual revolution, and the protests against Vietnam War. The movement was shaped up by the rejection of the social norms of hippies’ parents but evolved to embrace more specific political and societal goals, including the withdrawal from Vietnam, environmentalism, gender equality, and the expansion of civil liberties. “The Electric Kool-Aid Acid Test” by Tom Wolfe is an excellent non-fiction work that allows to see the movement from the inside and in the specific details of the daily hippie life. Even though the
A 50 mL buret was obtained and was washed with NaOH solution. After filling the buret with NaOH (titrant) and preparing the KHP (analyte) in the Erlenmeyer flask, the solutions were titrated. The volume used from the NaOH solution was recorded. C. Determination of the Acidity of Soft Drinks First, the soft drinks were heated.
Title: Stirring up the Bittersweet Truth: Sugar and Artificial Sweeteners Hook: All sugars can be chemically and physically addictive to the body, sometimes the outcome is not worth the pleasure when it can lead to an early death. Thesis: When it comes to Sugar and artificial sweeteners is one healthier than the other? *** POINT 1: Over consumption of sugar leads to weight gain, obesity, and other health risks.
The chemical equation for this experiment is hydrochloric acid + sodium thiosulphate + deionised water (ranging from 25ml to 0ml in 5ml intervals) sodium chloride + deionised water (ranging from 25ml to 0ml in 5ml intervals) + sulphur dioxide + sulphur. As a scientific equation, this would be written out as, NA2S2O3 + 2HCL + H2O (ranging from 25ml to 0ml in
Weaknesses: First, Jamba Juice’s initial surge in store openings, coupled with mismanaged growth patterns, placed a strain on the company’s cash reserves. Second, a further lack of financial discipline within the company allowed for huge increases in operating expenses. Third, although Jamba Juice initially gained popularity due to innovative products, their product offerings quickly became outdated and unexciting. Fourth, the seasonality of cold drinks created stagnant revenue during Fall and Winter months. Fifth, Jamba Juice initially relied on word-of-mouth advertising, but failed to create a viable marketing strategy as they expanded nationwide.
Many people buy strawberry jam since they are cost effective and it is one way to eat breakfast with your bread and it is cheaper than other jams. The two jams listed above have a cheap price in spite of their large size with exception of INNA Jam. INNA jam is priced at $13.50 as they said they used a special type of strawberry and many good ingredients. However, some people may not buy INNA jam as they have high price and customers may like sugar free jam than high sugar jam. Nutrient Factors
