With a run-of-the-mill working group, performance is a function of what the England found itself territorially and financially falling behind its rival Spain in the early seventeenth century. So, we are unable to identify magnesium carbonate from calcium carbonate. Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). 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 chemical equation is:MgO + 2 HCl = MgCl2 + H2O Is magnesium oxide MgO ionic or covalent? $$\ce{k = A e^{-E_a/(R T)}}$$, To make our rate law like this: one mole of magnesium chloride and one mole of water are given.

Hydrochloric acid is a corrosive liquid. Let's write a balanced equation for this reaction. And then the $\ce{H3O+}$ oxidises the magnesium like so: $$\ce{2H3O+ + Mg -> Mg^{2+} + H2O + H2}$$. Set up the apparatus as shown in the diagram. The magnesium term may appear zeroth order if the magnesium is in far excess, so significantly lowering the initial input of magnesium will probably result in the correct rate law. If a graph of volume (y-axis) against time (x-axis) is drawn, the slope of the graph is steepest at the beginning. Magnesium + 2 Hydrochloric acid --> Magnesium chloride + b. A.)
