Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

concerning equilibrium is not true? A) A system that is disturbed from an equilibrium condition responds in a manner to restore equilibrium. B) Equilibrium in molecular systems is dynamic‚ with two opposing processes balancing one another. C) The value of the equilibrium constant for a given reaction mixture is the same regardless of the direction from which equilibrium is attained. D) A system moves spontaneously toward a state of equilibrium. E) The equilibrium constant

Once some products are formed the reverse reaction can take place to reform the reactants. In a closed system the concentrations of all the reactants and products will eventually become constant. Such a system is said to be in a state of dynamic equilibrium. The forward and reverse reactions continue to occur‚ but at equilibrium the

I’m pretty much angry every day and it’s pretty much always for the same reason: My Chemical Romance. I first listened to MCR when I was 11 or 12. I heard a song called Cancer while creating a playlist on a website called 8tracks. My friend told me to put the song on the playlist so I did. It was a playlist inspired by The Fault in Our Stars by John Green. The song was a sad one and I didn’t really look into them much further because I already heard a few other songs (in passing‚ you could say)‚

purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the equilibrium of ferrocyanide and ferric ferrocyanide that it is an equilibrium shift to the left after adding NaOH. Experiment and Observation: The

Position of Equilibrium * There are many equilibrium mixtures possible for a given chemical reaction‚ depending on the concentrations of solutions‚ the pressure of gases and the temperature of the reaction. * The term position of equilibrium can be used to describe a particular set of equilibrium concentrations for a reaction. * If either the temperature‚ pressure or concentration of one of the substances changes‚ then the concentrations of all the substances will change until a new

formation of chemical bonds? Valence electrons are the electrons that are on the outermost shell of the atom’s electrons which are can be either given away‚ added‚ or to be shared. When these electrons are given away‚ added to or shared‚ there is a chemical change occurring and the compound that is formed is changed from the original elements. This is called bonding which is pretty much the realm of the electrons. It is the sharing of electrons from each atom that define the chemical bond. Because

The focus of Case 4 is how poor communication can effect an organization. Communication is essential to the survival of any organization. A lack of effective communication will result in little to no coordination and cooperation‚ resulting in decreased performance. In assessing Strayhorn’s communication effectiveness‚ one can see the negative impacts EI experienced because of his approach. Two of the biggest factors dampened by his style were morale and productivity. In addition‚ failure to address
