Step 2: Count the number of atoms of each element on both sides Clark (2002) explains that, finely divided chemical solids have greater surface area than chemical solids in lumps. At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. It takes place because magnesium is more reactive than hydrogen so it displaces it in the chloride compound. Description: Magnesium is placed in cold and hot water. Beryllium forms a strong oxide layer (similar to that of aluminum) which slows reactions down until it has been removed. Copyright 2012 Email: 5 What salt is formed from hydrochloric acid and magnesium oxide? Keerti added dilute Hydrochloric acid to four metals and recorded her observations as shown in the table given below: Metal Gas Evolved Copper Yes Iron Yes Magnesium No Zinc Yes Select the correct observation(s) and give chemical equation(s) of the reaction involved 3. 3 cm of magnesium ribbon typically has a mass of 0.04 g and yields 40 cm3 of hydrogen when reacted with excess acid. There will be a change in temperature of the test tube, slight fizzing of gas bubbles,then the magnesium ribbon will dissolve into water, leaving in blue. The equation for the reaction is:magnesium + hydrochloric acid magnesium chloride + hydrogen. The collision theory describes how the rate of reaction increases (the time taken for the magnesium ribbon to disappear when it is reacted with hydrochloric acid) when the concentration of HCL increases. In the third flask there is one quarter of the stoichiometric quantity of Mg so the balloon is noticeably smaller than the other two since the Mg is used up before all of the HCl is converted to hydrogen gas and the indicator stays red, showing that there is still acid present. The quantity of Magnesium metal used will be held constant by way of using equal lengths of Magnesium ribbons and equivalent weights (in grams) of powdered Magnesium metal.All the reaction will be carried out under a constant temperature (room temperature of 25.
