chemistry
1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. In the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride. The hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste; corrode active metals, forming metal chlorides and hydrogen; turn litmus red; neutralise alkalis; and react with salts of weak acids, forming chlorides and the Magnesium, symbol Mg, silvery white metallic element that is relatively unreactive. In group 2 (or IIa) of the periodic table, magnesium is one of the alkaline earth metals. The atomic number of Magnesium(s) + Hydrochloric acid(aq) = Magnesium Chloride(aq) + In the reaction when the magnesium hits the acid when dropped in, it fisses and then disappears giving of hydrogen as it fisses and it leaves behind a solution of hydrogen chloride. The activation energy of a particle is increased with heat. The
This theory states that as the temperature rises, more energy is given to the particles so their speed increases, this increases the number of collisions per unit of time. 2 10 20 30 40 50 Amount of H2 produced after 10s 7. If this experiment was accurate it would be also a curve but if you made it into 1/time the result would be a straight line showing a clear relationship. For particles to react:- a) They have to collide with each other. Putting the probability theory and the kinetic theory together this now gives us a statement which accounts for the 100% increase in the rate of reaction in a 10K rise. We can measure reactions in two ways: 1) Continuous:- Start the experiment and watch it happen; you can use a computer "logging" system to monitor it. 2) Discontinuous:- Do the experiments and take readings/ samples from the experiment at different times, then analyse the readings/samples to see how many reactants and products are used up/ produced. volume with 1 mole 24,000 To get the maximum mass we can use: Mass = moles x RAM. To get a fair reaction we had to keep the amount of magnesium the same and the concentration of the acid. Watching a colour fade or increase. Because the reaction reacts one mole of magnesium to two moles of hydrochloric acid we have to make sure that even with the lowest concentration of acid we still have an excess of acid. The number of particles with > EA is proportional to the total area underneath the curve. 004 moles so the amount of acid that we needed was double that so that equals 0.
