Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

1. Are any of the lab values in Table 1 out of normal range? Are they too high or too low? Her serum creatinine is high. Creatinine is completely filtered from the blood (not as well of a marker for kidney function as inulin because some is secreted‚ but still a good marker of kidney function) and excreted in urine so for her to have more than 0.6-1.2mg/dL in her blood is not normal. Her blood urea nitrogen (BUN) levels are also very high. They should only be around 7-18 mg/dL. Her serum calcium

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006).

synthesized 2‚ 3-dioxo-1‚ 2‚ 3‚ 4-tetrahydro quinoxaline-6-sulfonyl benzimidazole (s) were performed on adult earthworm (Pheretima Posthuma). The observation was made for the time taken to paralysis and/or death of individual worms up to four hours of the test period. Paralysis was said to occur when the worms did not revive even in a vehicle. Death was concluded when the worms lost their motility followed with fading away of their body color. The selected newly synthesized 2‚ 3-dioxo-1‚ 2‚ 3‚ 4-tetrahydro

was then used to transfer 4ml of anhydrous ether to the vial. The syringe was then utilized to transfer 0.8 ml of this solution and the reaction was allowed to proceed until the solution turns brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and
