To determine the density, you would first find the moles actually produce by using the Law of Partial Pressure and the Ideal Gas Law. The equation for the reaction is: magnesium + hydrochloric acid → magnesium chloride + hydrogen. since the properties weren't changed, it was a physical change. The thing to do before an experiment is to research it carefully then set up an experiment taking some safety precautions and then observing carefully. When magnesium reacts with hydrochloric acid, hydrogen gas and soluble magnesium chloride are produced according to the following equation: It takes place because magnesium is more reactive than hydrogen so it displaces it in the chloride compound. Count the number of drops you have used. These revision notes on reactivity series of metals experiment observations should prove useful for the new AQA, Edexcel and OCR GCSE (9-1) chemistry science courses. In addition, you will use the information to determine the limiting reactant in the reaction. Repeat 15 times. Place about 5cm depth of the acid in each of the five test tubes; Place a small piece of each of the three metals above. In the reaction between hydrochloric acid and magnesium, the reaction occurs quickly. Magnesium will react with hydrochloric acid, because it is higher in the reactivity series than hydrogen.
