Inflation’s effects on an economy are various and can be simultaneously positive and negative. Negative effects of inflation include a decrease in the real value of money and other monetary items over time‚ uncertainty over future inflation which may discourage investment and savings‚ and if inflation is rapid enough‚ shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include ensuring central banks can adjust nominal

Billy Kong Chem&163 Lab Report 1 Analysis of Acids‚ Bases‚ pH and Salt Purpose: Explore various methods for determining the characteristics of acid/base solution. The goal of this experiment include the investigation of various acid/base indicators‚ calculating the change of pH with concentration‚ change of pH due to the addition of salt and different between strong and weak acids/bases. Safety and Disposal: Use extreme caution when handling concentrated acids and bases. Dispose of all

Katie Yang Ms. Molin Advanced English 10C 7 May 2010 The Secret Behind Food That People Eat The number of consumers has now risen to 200‚ 000‚ 000‚ subjected everyday to a bombardment of poisons in their food and drugs while lying at the mercy of “respectable corporations” (Fuller). While the chefs and sou chefs cooked their customers’ orders‚ they thought nothing of it. They served it to their customer and while that customer ate‚ one had an allergic reaction. The customer whose name was Jorma Takala

digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7)‚ and pepsin is no longer effective. "Pepsin (biochemistry)." Encyclopedia Britannica Online. Encyclopedia Britannica‚ n.d. Web. 10 Dec. 2012. Research Question: Does changing the pH of pepsin affect the ability to break down the protein (mass of jello). Variables: independent- Ph level dependent- The mass of the jello

of the effects of food allergies‚ and how they can directly impact another’s health status. What I have come to realize is that I may not be able to cure the world of allergic reactions‚ but I can present a resolution of prevention. Though the people may not be perfect‚ I believe the world can become a safer and healthier place for those affected by allergens‚ by promoting anaphylaxis awareness in

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

The Effects of Mass Food Production on the World as a Whole Robert Dupell ANT 340 Mass food production has become an increasing issue in the world. It was created to help solve the lack of nutrition problem that was created by the staggering population growth of the human race. Short term it has solved the issue it was created for. But there are inherent risks that come with this type of food production. Mass food production causes a great deal of stress on the environment. The land‚ air

for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls varied for each pH buffer
