Between me and the athletes there were several more tables‚ all filled with energetic dancers‚ thoughtful theater kids‚ and noisy band members with their instrument cases spread over the table along with the peanut butter sandwiches and bags of carrot sticks. I didn’t feel like I matched any of these groups. At my old school‚ I was friends with everyone‚ and we didn’t have to share a hobby in order to have plenty in common. It seemed as though all of these groups shared one specific thing with each

The ratio of the With the results obtained accurately‚ calculations were made to find out the following: * The mean of each group’s data * The standard deviation of each group’s data As each trial consist for 5 different sizes of the agar cubes (1cm‚ 1.5cm‚ 2cm‚ 2.5cm and 3cm) and that the trials are repeated 5 times‚ we expect that results will be as follows: * As the size increases‚ it will take a longer time for the pink color (phenolphthalein indicator) to reach the center

An investigation to measure the percentage light transmission‚ using a colorimeter‚ through a solution‚ from pH 2 – pH 9‚ in which jelly cubes were immersed over a 24 hour period Interpretation Written Communication of the Data C1 Pepsin is an enzyme that works in the stomach and has an optimal pH between pH 1 and 4 or in acidic conditions. From our graph it can be seen that that the lowest mean percentage light transmission for pepsin is when the buffer has a pH of 2. Trypsin is an enzyme that

Discussion- 1. It is shown that diffusion took a lot less time when the Jelly block was smaller and had a high Surface Area/Volume ratio. The acid diffused through the 5x5x2.5mm block in about 3 minutes and 5 seconds‚ but the 10x10x5mm block took around 11 minutes and 25 seconds to fully diffuse‚ The smaller block has the high Surface Area/Volume ratio‚ which is why it was the fastest to fully diffuse out of the five Jelly blocks. 2. The acid diffused in the smallest block much more rapidly‚The

Materials used in the practical consist of blocks of agar jelly containing indicator‚ a sharp knife‚ used to cut the agar jelly into the recommended sizes‚ diluted sulphuric acid (300mL) ‚ ruler‚ to measure the sizes of the cubes‚ absorbant paper towel‚ three 250mL beakers‚ and a measuring cylinder. To perform this experiment‚ the following procedures will need to be follow precisely: Obtain three blocks of agar jelly. Carefully cut three cubes‚ as close as possible to 1 cm‚ 2 cm

Title: What is the effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement

potassium dichromate is an orange inorganic chemical reagent and methylene blue is a chemical compound commonly used for staining because of its color blue. These three substances have 158 g/mole‚ 294 g/mole and 374 g/mole‚ respectively. A jelly-like substance‚ agar-water gel in a petri dish was used as a medium for diffusion since water and air‚ as a medium‚ are not controllable
