In this chemistry experiment, we aim to determine the enthalpy change for the displacement reaction between zinc and copper sulfate solution. By measuring the temperature change over a period of time and using calculations, we can obtain the enthalpy change and thermochemical equation for the reaction. The procedure involves adding excess zinc powder to the solution and recording the temperature every 30 seconds for 8 minutes. We also discuss how to calculate the percentage error and possible reasons for differences between the experimental and accepted values. This experiment is a great opportunity to learn about enthalpy, displacement reactions, and thermochemistry in practice.

Calculating the empirical formula of a compound
This chemistry experiment teaches you how to calculate the empirical formula of a compound by using molar ratios and mass calculations. By exploring the reaction between magnesium and oxygen, you can determine the empirical formula of the compound formed. The experiment involves heating magnesium ribbon with oxygen to produce magnesium oxide, recording the masses of the substances before and after the reaction, and calculating the molar ratios to determine the empirical formula. Learn about the procedure, requirements, and calculations involved in this experiment, and explore questions that will help you further understand the concept of empirical formulas.
