Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid‚and plan an investigation to test it out.The Metals given:Calcium‚Aluminium‚Iron‚Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element

reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it is more reactive. Aluminum + Iron Oxide: Aluminum will displace Iron because it is more reactive. Zinc + Hydrochloric acid: Zinc will replace Hydrogen because it is more reactive. Copper + Hydrochloric Acid: Copper will not displace Hydrogen because copper is more reactive. Magnesium + Hydrochloric acid: Magnesium will displace Hydrogen because it is more reactive

normal circumstances‚ room temperature‚ magnesium metal‚ Mg‚ reacts very slowly with the oxygen‚ O‚ in the air. However‚ as magnesium is heated‚ it reacts quicker with the oxygen and burns with a white light to produce MgO. To protect others from the smoke‚ containing Magnesium Oxide‚ the crucible had to remain covered. Some magnesium oxide escaped‚ when the crucible was not covered. The crucible had to be slightly ajar when heating up the magnesium‚ so that oxygen could get to the reaction

contribution to chemistry. Research Question -Magnesium reacts with hydrochloric acid. If you increase the amount of magnesium added to hydrochloric acid will it change the mass of the initial product? Hypothesis -If you increase the amount of magnesium added to hydrochloric acid then it will increase the amount of mass of the initial product. Variables -Independent Variable: amount of magnesium. Dependent Variable: the mass of the product of magnesium added to hydrochloric acid. Control:

state of reactants‚ and a catalyst. This experiment regarding the factors that affect reaction rate tests the effects of increased concentration and temperature of the hydrochloric acid solution (HCl) and also the effect of increased surface area of magnesium metal (Mg). When glow sticks are immersed in a hot water bath‚ it is proven that they glow with greater intensity. This proves that an increased temperature has an effect on the reaction itself‚ allowing molecules that make up the liquid inside the

heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid. What I already know Magnesium reacts with most

The purpose of this lab experiment was to take the reagents of magnesium and Bromobenzene to create the Grignard reagent of phenylmagnesium before its converted to the final product of triphenylmethanol. Then the product was purified via methods such as recrystallization and filtration‚ before it was finally characterized via a series of methods such as TLC‚ melting point‚ IR‚ H NMR‚ and C NMR. Before the lab even began‚ the first thing done to ensure a safe successful reaction was to oven dry all

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double displacement of compounds or elements . Hypothesis: Part 1 : I believe that magnesium burning in oxygen will have synthesis reaction because the magnesium will react with the oxygen in the
