What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well

rate of collisions will also double. Thus if the collisions double then the reaction between Magnesium ribbon and Hydrochloric acid will also more or less double. The particles of any gas or liquid can only react if they are supplied with energy. Thus at low temperatures the particles just bounce of each other since they do not have enough energy. The reaction happens only when the particles gain kinetic energy and thus move faster. This increased speed increases the chances of the collisions between

way to take an input and always have the same output‚ otherwise known as a 1 to 1 function. An ideal hash function is when this same process always yields a unique output. Hash Function Choosing a hash function that minimizes the number of collisions and also hashes uniformly is another critical issue. It is also used in many encryption algorithms. Main formula for hashing index is: H(k)=k mod m H(k) means that where is the location of that key or data. K mod m‚ content is the result of

Foundation for Traffic Safety reports that drowsy drivers are involved in an estimated 109‚000 motor vehicle accidents resulting in injuries each year. Furthermore‚ it is estimated that driving while sleep-deprived plays a role in 6‚400 fatal auto collisions annually. How dangerous is drowsy driving? Fatigue and drowsiness can have a significant impact on people’s abilities to safely operate their motor vehicles. When motorists have been awake for extended periods of time‚ or are highly fatigued‚

The Chevy Silverado Chevrolet vehicles without any doubt are giving consumers the quality they deserve. Chevrolet has received more 2013 J.D. power initial quality awards than any other automotive brand. According to the 2013 J.D. Power and Associates Initial Quality Study‚ Chevrolet received five segment awards‚ meaning that Chevrolet has received the most than any other car brand. With that being said‚ the Chevrolet Silverado truck had the honor to be one of the segment award recipients. I

From an introductory‚ tranquil scene of both moose and wife‚ then a detailed description of the collision and the aftermath‚ ending with the speaker pondering on the chance of such an event and if a supreme intelligence was involved. The speaker’s use of “sometime” in the opening stanza allows him to detach himself from the collision and also highlights that he has no stake over the outcome of the crash. The

Introduction In this coursework I will be talking about the experiments‚ which I have done over two weeks. This gave different results by using different concentrations of hydrochloric acids (HCl) and indigestion relief tablet. I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion

Aims The aims of this investigation are: 1. To find the rate equation of the reaction of hydrogen peroxide and iodide ions. This will be achieved by using an iodine clock method and colorimetric analysis. 2. Draw a graph of rate against concentration for each reactant (Hydrogen peroxide‚ potassium iodide and H+ ions). 3. Finding the order for each reactant 4. Finding the rate-determining step. 5. Proposing a mechanism for the reaction. 6. Using Arrhenius’ equation to find the activation

1.Which statement is true about broadcast and collision domains? Adding a router to a network will increase the size of the collision domain. The size of the collision domain can be reduced by adding hubs to a network. The more interfaces a router has the larger the resulting broadcast domain. Adding a switch to a network will increase the size of the broadcast domain. 2. Which switching method describes a switch that transfers a frame as soon as the destination MAC address is read? fragment-free
