Assuming a the solution in the plastic beaker has the same specific heat capacity as water, i. As far as you can, list out the major sources of inaccuracy in the experiment and suggest ways to improve them whenever possible.
Determination of the Enthalpy Change of a Reaction Determine the enthalpy change of the thermal decomposition of calcium carbonate by an indirect method based on Hess' law. Write the equation for the formation of calcium carbonate under standard conditions.
Magnesium Hydroxide was mixed with water and the change in heat was measured using a thermometer.
Moreover, the solution should have unit activity 1mol dm The experiment was repeated with 1. Essay on Chemical Reactions And The Chemical Reaction - Introduction: In this lab, I determined the amount of heat exchanged in four different chemical reactions only using two different compounds and water.
In a chemical reaction, bonds must either be made or broken, this involves an enthalpy change.
Why is this principle useful?
