The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

if antimicrobial concentration increases‚ then the zone of inhibition will increase because the higher the concentration‚ the more the antimicrobial will disinfect the area of bacteria and thus the zone of inhibition will increase.The results of the lab do support my hypothesis. Paragraph 2: My antimicrobial was bleach. Bleach contains hypochlorous acid which “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional and leading to cell death”(publications.nigms.nih.gov)

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

In conclusion‚ even though the lab procedure is not about moles‚ most of the calculations are and this is one lab where the concept of

Bread and Wine Ignazio Silone 11/26/04 Bread and Wine is a timeless story of the struggle of one man in a changing country. The Country is Italy. The time is the 1930 ’s‚ however the struggle is against fascism. To understand where the book is coming from‚ one must first understand where the author himself was coming from. Ignazio Silone can be closely related to the main character in the book; Pietro Spina. He was born early in May in the year 1900. Living in a small village in the region

potential to damage crops extensively‚ and thus‚ damage society as well through shortage of food or even famine. In addition‚ in countries that depend on the production of agricultural goods like Canada‚ the effects of acid rain can be tremendous. In this lab‚ we have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April

Title: The Effect of Nicotine on the Heart Rate of the Lumbriculus Variegatus Introduction: Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab‚ the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity‚ especially in the nervous or cardiovascular systems. In this lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control

one of the tests‚ so that data is lost. Specific errors include measuring the entire test tube from top to bottom instead of measuring the exact distance traveled by the filter paper‚ making the test results not plausible. The results of this lab proved several things. The results of the first test show that a higher enzyme concentration causes a faster rate of the substrate being broken down. This means that the effect of enzyme concentration on enzyme activity is a positive effect and speeds
