In Jane Austen's novel "Pride and Prejudice," Mr. Collins is a character who is quite memorable due to his ridiculous behavior and ridiculous beliefs. One of the key aspects of Mr. Collins' character is his age, which is mentioned several times throughout the novel.
Mr. Collins is described as being a man in his late 20s or early 30s, which was considered to be relatively old for a single man at the time the novel was written. This is significant because it indicates that Mr. Collins is at an age where he should be considering marriage and settling down, but he has not yet done so.
This is partly due to the fact that Mr. Collins is a clergyman, and as such he has been able to postpone marriage in order to focus on his career. However, it is also clear that Mr. Collins is not particularly popular with the ladies, as he is described as being pompous and self-absorbed.
Despite his advanced age, Mr. Collins is still very much a child in terms of his emotional maturity and his understanding of the world. He is heavily influenced by his patron, Lady Catherine de Bourgh, and is prone to acting in a manner that is self-serving and obsequious.
Overall, Mr. Collins' age is an important aspect of his character because it helps to explain why he is the way he is. It also serves as a contrast to the younger characters in the novel, such as Elizabeth Bennet, who are much more self-aware and confident.
Practical
Continue timing until no more gas appears to be given off. When sodium thiosulphate and hydrochloric are mixed, a yellow precept of sulphur is produced. When the temperature is raised, molecules move faster, and therefore collide more frequently. The weight inconsistencies were small therefore, a low significance error Use at least two sets of experiment to get average of results to minimize the impact of experimental errors Determination of end of reaction was sometimes uncertain. During the reaction, the two substances produced bubbles, creating smoke and became warm with a smell that is irritating to the human nose.
The rate of reaction of magnesium with hydrochloric acid
Introduction In acid-base chemical reactions, there are four main variables, which influence the rate of reaction. Obtained chiefly from magnesite, dolomite, and bodies of salt water, it is used in structural alloys, pyrotechnics, flash photography, and incendiary bombs. The syringe could have stuck on the barrel around it giving me lower readings on curtain points or when the reaction stopped. Eye protection must be worn. This is because the hydrogen ions H+ from the acid I have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. Apparatus: Stop Clock — Water — Acid — Test Tube rack — Test Tube — Magnesium — Ruler — Scissors — Beaker — Measuring Cylinder — Safety: Safety is a very important part of this experiment as we are working with a corrosive chemical that is very dangerous. Make sure you put on your personal protective clothing and safety goggles.
Rates Of Reactions Between Hcl And Magnesium Ribbon, Sample of Courseworks
Method For each separate experiment I needed: 1 Conical Flask 1 Large Syringe with measurements 1 Bung attached to Rubber Tubing 1 Stopwatch 1 Measuring cylinder 8cm of cleaned Magnesium Ribbon 20cm2 of 2M Hydrochloric Acid First I got all the apparatus on the list. All the experiments have to be repeated at least two times to make an accurate set of results. I made these concentrations by adding a curtain amount of water to the 2M solution, but still maintaining the same amount 20cm3. Most of the equipment is glass so I had to be careful not to damage it, as shards of glass can cut though skin. Retrieved March 8, 2012, from newton.
Rate of reaction between magnesium ribbon and hydrochloric acid.
This is a low significance error since we based mostly on the disappearance of magnesium into the acid rather than disappearance gas bubbles. Even after disappearance of magnesium ribbon, gas bubbles were evident, implying the reaction was incomplete. As the temperature increases the Chlorine and Magnesium Lab Introduction During my observation I noticed that when 10mg of magnesium metal was added to the beaker a shaded area appeared on the bottom of the beaker. The lowest concentration 0. I will wear non-porous gloves when handling HCl, to avoid contact with skin.
Reaction (rate) between magnesium ribbon and hydrochloric...
Throughout the experiment, we diluted the This complies with my prediction. However, the one thing that remains the same for every reaction is that the more effective collisions there are, the faster the reaction occurs. If I was to choose the temperature of the acid as my independent variable, and if I were to heat the acid too much it may boil and produce a corrosive gas, which would life threatening. A single replacement reaction involves one element replacing another element in a compound. Figure 1: Experimental set-up of HCl-Magnesium reaction Results and Observations During the reaction, the water bath in the gas delivery system showed gas bubbles ascending to the gas cylinder.
It is based on the idea that for a chemical reaction to take place, the reacting particles have to hit each other hard enough to break or form new bonds. Use your graphs and calculations in step 2 to help you. This reaction was very slow with a time of 4, 43. Heat likes to transfer from warm to cold. This tells me that there is a significant change even when I decrease the concentration by 0. In this experiment, magnesium is going to be dissolved in hydrochloric acid and are measuring the amount of hydrogen produced. For my experiment my independent variable will be the concentration of the acid.
Rate of Reaction of Magnesium and Hydrochloric Acid
At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. Reactants with high surface area provide a greater binding surface for other reacting molecules, and therefore increase the number of successful collisions at any moment. Therefore, considering concentration factor and surface are factor of reactants it is evident that the rate reaction curve trends would not be linear as expected, but rather exponential. This idea also explains why the reaction between magnesium and hydrochloric acid slows down as time goes on: 1 2 — Acid Particle — Water Molecule — Magnesium Atoms 1. . However the acid is in excess, so it is mainly the loss of magnesium surface area becomes smaller that causes the change in the rate. The largest difference in my results, on the 2M concentration for the same time, was 5cm3 apart which is a 50% error, but the average seemed to be near enough to be in the trend of results.
Experiment: Demonstrate the effect of surface area on the rate of a reaction
. It is also possible to collect the gas in an inverted measuring cylinder in place of the gas syringe. Include the following information in your laboratory report, due at the beginning of the laboratory period next week. . The higher the concentration of HCL you use, the less time it takes for the magnesium to disappear and so the 2 pages, 864 words For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution.
