Reaction rates of Mg mixed with 2HCl

Reaction rates of Mg mixed with 2HCl INTRODUCTIONThe reaction type we are looking at and testing is neutralisation. This reaction occurs when an acid reacts with a base. The base reactant should be neutralized. In this case the acid is reacting with a metal, magnesium. The magnesium will be mixed with hydrochloric acid and should be neutralized. Magnesium chloride and hydrogen will be formed when the reaction takes place.2HCl + Mg - MgCl2 + H2Reaction rate is the speed of which a reaction takes place. If A reaction has a low rate, this means the molecules are combining at a lower speed. A way of measuring the rate of a reaction is recording how fast one of the reactants disappears. A theory used for the rate of a reaction is the collision theory. It states that the more collisions of molecules, the more combinations, and the reaction will be faster. The number of collisions in a reaction is not always the same.Hydrochloric acid 05They will be different according to what substance is used and other variables. The main th ings that effect the collisions include the concentration of a reactant, and the temperature. The concentration of a reactant changes the amount of collisions because it has increased molecules in an amount of space. This makes it more crowed and less chance of a molecule moving through an area without colliding. When the temperature is increased, molecules will move faster. This will also raise the number of collisions because when molecules are moving faster they will collide more frequently. This theory should mean that when we use different concentrations of hydrochloric acid, the rate of reaction will change.The independent variable is the concentration of hydrochloric acid. This concentration will effect the reaction by speeding it up and slowing it down. This happens because in a high concentrated acid...

Best Picture Oscar Winners at the Academy Awards

Best Picture Oscar Winners at the Academy Awards Since its inception, the Academy Awards has honored one film each year, calling it the Best Picture. The announcement of the Best Picture Oscar winner is often the highlight of an Academy Awards ceremony. Below is a list of every single Best Picture Oscar award winner.   * Please note that the years listed below are the years the films were created, i.e. the Academy Award ceremony that honored these films were held in the spring of the following year.
