To decide which reactant I will use for my investigation, I will do preliminary experiments to decide this. Preliminary work I will be doing some different preliminary experiments. The preliminary will allow me to decide which reactants to use for my investigation and how much of that reactant to use in each experiment. Experiment 1a: Which reactant reacts best? 1. Display 3 beakers. In: * Beaker 1 place some chalk * Beaker 2 place some marble chips * Beaker 3 place some strips of magnesium 2. In each beaker pour some hydrochloric acid and observe the reaction. 3. Estimate the rate of the reaction on a scale of 0-5 (0= no reaction, 1= very slow, 2= slow, 3= medium, 4= fast, 5=...
