Enthalpy of formation of calcium carbonate essay

enthalpy change of formation of calcium carbonate

In brief the reactivity series of metals is a list in which metals are ranked according to their reactivity, from the most reactive metals such as Pottassium at the top to Gold the least reactive metal at the bottom The formation of bonds is exothermic, energy is lost to the surrounding; on the other hand, breaking bonds is endothermic, energy is taken in The experiment was repeated with 2.

Reaction of calcium with dilute hydrochloric acid 1. The aim of the experiment is to find out how much energy is produced when these alcohols are burnt and to see if there's a relation between how many, and how strong the bonds are between molecules in the elements burnt, and how quickly the water is heated up.

Enthalpy of formation of calcium carbonate Essay Paper type: Essay Words:Paragraphs: 19, Pages: 7 Publication date: August 10, Sorry, but copying text is forbidden on this website! Indeed, the concentration of the hydrochloric acid just affects the rate of the reaction.

Enthalpy of formation of calcium carbonate essay

The two compounds used were Magnesium Hydroxide and Citric Acid. As far as you can, list out the major sources of inaccuracy in the experiment and suggest ways to improve them whenever possible. The experiment was repeated with 2. Approximate concentration of hydrochloric acid is not considered as one of the errors. State the law which you have used in order to answer Question 5. In other words, an energy change is path independent, only the initial and final states being of importance. As the acid has very high specific heat capacity, the errors in calculating the heat change of the reaction will be very significant if the heat absorbed by acid is not taken into account. This path independence is true for all state functions 8. T in order to calculate the heat absorbed by the acid accurately. In brief the reactivity series of metals is a list in which metals are ranked according to their reactivity, from the most reactive metals such as Pottassium at the top to Gold the least reactive metal at the bottom Should we measure the volume of acid with a measuring cylinder?

Draw an energy-cycle linking Equations 1, 2 and 3 together, you must include reactions that had not been performed in the experiment. This is because the heat absorbed by the acid must be counted when calculating the heat change of the reaction.

This law helps us to define the standard enthalpy change of a reaction. Calculate the heat of formation of calcium carbonate.

Heat formation

As far as you can, list out the major sources of inaccuracy in the experiment and suggest ways to improve them whenever possible. This law helps us to define the standard enthalpy change of a reaction. I will do three sets of experiments changing first the concentration of iodide ions, then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is taking place I will use these four because they should give me clear results, and they range from short chained to long-chained hydrocarbons, so patterns should be easy to spot in the conclusion 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. This is because the heat absorbed by the acid must be counted when calculating the heat change of the reaction. Therefore the area that I am looking at is reactions involving metals and the heat energy that is evolved when these take place.
