Purpose The purpose of this investigation is to determine the effect that varying temperatures have on the rate of a reaction. Introduction Based on the Kinetic Molecular Theory, the central idea of the collision model is that molecules must collide to react. Therefore, the greater number the number of collisions per second, the greater the…
e) The reaction proceeds quite rapidly during the initiate mixture of Hydrochloric acid and Calcium Carbonate chips. Between 1-3 min the reaction is proceeding vigorously, however later on between 4-6 min the reaction tampers off and the consumption in HCl lowers per min intervals. Evaluation f) The experimental design appears to be very vague on…
There are many organs and structures that make up the Digestive system and these organs or parts have key functions or roles to play which could include one or more of these: DIGESTION – mechanically or chemically breaking macromolecules to smaller units Mechanical: large food molecules are shredded, torn and ground; this helps to increase…
