Reaction Essays

Aim: The aim of this investigation is to perform various double replacement reactions with known substances and record the qualitative observations. Furthermore, writing the equations for the reactions and apply the rules of solubility to see if every color change

The focus of this study was to investigate how the participation of different sports activities affects the reaction time. Two hypotheses were established based on my research question: “People who carry out sports should have a faster reaction time than

Aim: The aim of this experiment is to compare the rate of reactions of the reaction of yeast with the three different carbohydrates, namely glucose, sucrose, and lactose. Hypothesis: The rate of reaction should be fastest in the reaction between

CaCO3 (s) + 2HCl(aq) –> H2O (l) + CO2 (g) + CaCl(aq) Variables: Variable Methods of Measurement Independent Size and Surface area of the CaCO3 particle; in chip of approximately 3x3x3 mm in size or in powder form. Pre-measured. Materials

The aim of this investigation is to calculate the values of x, y and z and hence the overall order of the reaction. Prior to proposing a possible mechanism for the reaction that is consistent with the suggested rate equation.

Esterification is the reaction of a carboxylic acid with an alcohol. This experiment is an esterification reaction between ethanoic acid and propan-1-ol when heated: CH3COOH(aq) + CH3CH2CH2OH(aq) <=> CH3COOCH2CH2CH3(aq) + H2O(l) The formation of propyl ethanoate is particularly well-suited to

To determine the enthalpy change of a displacement reaction (Between zinc and copper (II) ions) 5. Introduction : Excess zinc powder is added in a measured amount of aqueous copper (II) sulphate. The temperature change is then measured over a
