Increasing CO2 concentrations in the atmosphere‚ and thus the ocean‚ will continue to decrease the CO32- concentrations in the ocean and thus lowering CaCO3 saturation levels. In regions where the saturation state of aragonite or calcite is greater than 1‚ the formation of shells and or skeletons is favored whereas for values less than 1.0‚ the seawater is corrosive to CaCO3 (John M. Pandolfi). This corrosive condition results in dissolution. Dissolution of the carbonate minerals calcite‚ aragonite

The objective of this experiment was to learn the process of recrystallization and how this process removes the impurities from a pure solid compound. The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

specific heat of solids 1. Introduction Heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1oC. The specific heat of a substance is the heat capacity per unit mass. Thus‚ heat capacity = mass x specific heat. The specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Heat and temperature are really different quantities. Heat is a quantity of thermal energy‚ while temperature determines the

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Question: What antibiotics work best in preventing E. coli k12 from growing; amoxicillin‚ ampicillin‚ or ciprofloxacin? Hypothesis: If ciprofloxacin‚ an antibiotic‚ is added to petri dishes covered in live bacteria and left to sit for four to six days in an incubator at 37 degrees Celsius‚ then the petri dishes containing ciprofloxacin will have the largest zone of inhibition out of all of the other antibiotics tested because research shows that ciprofloxacin in one of the strongest antibiotic currently
