In addition, impurities may form on the surface of the magnesium metal therefore, slowing further the rate of reaction. Assume this reaction generates copper with a +2 charge. Reaction of metals with oxygen Look at how magnesium reacts with oxygen: /**/ The use of a gas jar full of oxygen can be used to combust other metals. The balanced chemical equation for this reaction is Mg (s) + 2 HCl (aq) produces MgCl 2 (aq) + H 2 (g), where the letter "s" stands for solid, "g" is gas and "aq" represents an aqueous solution. Add up the weights of the five 10 cm-long magnesium ribbons and obtain the average weight in grams. Different temperatures can either increase or decrease the speed of the particles in liquids or gases, causing particles to collect more energy, and to collide and creating chemical reactions when temperature is increased. This is as shown in the equation below: 2HCl (aq) + Mg (s) => MgCl2 (aq) + H2 (g). Immediately cork the flask to the prepared gas delivery system. During the reaction, the water bath in the gas delivery system showed gas bubbles ascending to the gas cylinder. Question: Do you think the balloon will expand to a smaller or larger diameter compared to Trial 3. From the experimentation the aims of the experimentation have been achieved. Plan an experiment to investigate the effect of decreasing the temperature on the rate of this reaction by measuring the volume of hydrogen produced. magnesium ribbon water dilute hydrochloric acid..... Two experiments were carried out. Determination of end of reaction was sometimes uncertain. Metals that react with oxygen produce oxides as their products. Use the average weight as obtained in 15 above and weigh of an equivalent weight of Magnesium powder (for this case 0.102 grams) and pour into the first conical flask containing the 3 M HCl acid, start your stopwatch, and immediately cork the flask to the gas delivery system. The experimentation procedures followed were standard for all the two sets of experiments conducted, including data collection mode. Magnesium (Mg) is known as a chemical element with the atomic number of 12. Reference this, Kiara Anderson, Laura Knott, Jackson Baker. These include the presence or absence of catalyst, temperature, concentration, and surface area of reactants. Make sure you put on your personal protective clothing and safety goggles. during the experiment, there was only one error which was the molecule strength was mixed up, instead of using the 1 molecule on 2 of the 40 ÌŠc tests we use 0.1 molecule this could have been avoided if we paid more attention to the equipment we used in the test. the higher the temperature the quicker or bigger the chemical reaction is when a magnesium ribbon is drop in the beaker of 25ml of hydrochloric acid. For a laboratory investigation, a student is instructed to place a 2.4 g sample of magnesium ribbon into 500 mL of a 2.0 M solution of hydrochloric acid. Repeat step 5 and 6 for 2M, 1.5M, 1M, and 0.5M HCL and keep all the acids ready on the working bench. A student obtains two strips of magnesium, Mg, ribbon that are each 3 cm long.
