Determining the empirical formula of magnesium oxide lab

Since multiplying the ratio by five gives the closest values to whole numbers, therefore the empirical formula of the oxide is Mg6O5. The third trial was not taken into account because the mass after combustion was not recorded. Uncertainty calculations: The uncertainties for masses in both tables will be: 0.01+0.01=0.02g Table one: Here are the… View Article

The effect of concentration on rate of reaction was investigated

Analysis: 1. How does reaction rate change according to concentration? Based on our processed data, the lower the concentration the faster the reaction. This also means that the higher the concentration, the slower the reaction. 2. Why is the cotton wool plug needed? The cotton wool plug is needed to absorb the amount of carbon… View Article

Design – Potassium Dichromate

Introduction: The reaction that is carried out in this design practical is between acidified Potassium dichromate and Iron wool. The reaction is a redox reaction. A Redox reaction (a short way of saying “reduction-oxidation reaction”) is the simultaneous transfer of electrons between multiple substances. The oxidation numbers or the oxidation state of atoms is changed… View Article

Measuring the Enthalpy Change for the reaction

Observation: 1) To start with, the copper sulphate solution is transparent blue colour. 2) At the fourth minute, using the glass rod to stir the solution as the Zinc powder is placed into the solution, the colour changes into dark turquoise and the solution fizzes due to the chemical change. 3) The Zinc powder then… View Article

Determination of water of hydration

Observation of copper sulfate No copper sulfate Light blue After heating for about 2-3 minutes, of the powder turns lighter and then into grey-white. Water released as vapor is observed from this point. After heating for another 2-3 minutes, of the powder turns into grey-white. After heating for 10 minutes, the whole part of the… View Article

Validating Hess’s law

Is the enthalpy change for a given chemical change the same whether the reaction takes place in a single stage or via several stages, provided the initial and final conditions are the same.
