During the reaction of the acids (HCl and H2SO4) with sodium hydroxide‚ we monitored the temperature change‚ since chemical reactions always absorb or liberate heat energy as they occur. Besides‚ the amount of heat transferred is proportional to the amount of the product that has been formed. By performing several reactions of HCl and H2SO4 with the base NaOH in which the amount varies‚ we determined the stoichiometric ratio in which these substances react. We start by monitoring the reaction of HCl

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Before I started writing this paper I put a lot of thought into the phrase "leadership development" and what it really meant to me. After all‚ I took this college level leadership class for professional development. I felt that the premise of this course was that leaders could be developed. If so‚ what are the factors that influence the development of leaders? Is there a single influence which dominate this development process? Do I have the ability to create my own leadership style and grow

Miracles Do Happen Sports and miracles kind of go hand in hand when athletes perform in games or practices. The Denver Broncos were down 24-0 at halftime against the San Diego Chargers‚ and they ending up winning 35-24 with 35 unanswered points. Many basketball games come down to the wire during March madness and many teams win by hitting buzzer beaters. For the USA hockey team‚ this miracle happened to swing their way. This special hockey team hit the biggest lottery numbers possible and took
