Enthalpy of formation of magnesium oxide

The important factors determining the metal—oxide interactions are provided. Guidelines are given in order to predict the interactions in such systems, and methods to desirably tune them are suggested. The review starts with a brief summary of the physics and chemistry of heterophase interface contacts.

Enthalpy of formation of magnesium oxide

MgO is small, white granular pieces, a fine white powder. HCl is clear and has a slight odour.

Enthalpy of formation of magnesium oxide

A gas is beginning to form, only a little bit. Feel the solution getting hotter while conducting experiment.

Enthalpy of formation of magnesium oxide

The MgO has completely dissolved in the HCl. The new solution is clear and odourless despite the previous odour of the HCl. Mg Mg is small grey chunks like little shiny stones HCl is clear and has a slight odour.

A lot of gas is forming. Feel the solution getting a lot hotter while conducting the experiment.

Many bubbles are forming. Bad odour is being conducted as the Mg and HCl mix. The Mg has completely dissolved in the HCl. The new solution is clear.

There is a very strong and bad odour. Almost smells like rotten eggs but not as strong. Therefore, the average temperature high for the MgO and HCl solution in trial 1 was Therefore, the average temperature high for the MgO and HCl solution in trial 2 was Therefore, the average temperature high for the Mg and HCl solution in trial 2 was This investigation was conducted in order to determine the enthalpy of formation for magnesium oxide by manipulation of the three equations given.

Standard enthalpy of formation - Wikipedia

Through experimentation it was found that the enthalpy of change for the combustion of magnesium is It is evident that the two equations which were used in this experiment were exothermic since the enthalpy of change that resulted was a negative value, therefore the experiment was successful.

Furthermore, the results are quite accurate as the value reached through the experiment, Since the percent error is a very small value it is evident that the experiment was a success, however this does not mean that it was perfect.

The Sources of error in this case would have been quite minimal resulting in small change that led to a value slightly lower than the expected value. One error that may have caused a lower enthalpy of change value than expected could have been that heat escaped from the calorimeter used during the experiment.

There were two holes on the lid of the calorimeter and one was being used for the thermometer, however the second, although very small, was left open.Interactions between metals and oxides are key factors to determine the performance of metal/oxide heterojunctions, particularly in nanotechnology, where the miniaturization of devices down to the nanoregime leads to an enormous increase in the density of interfaces.

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard r-bridal.com standard pressure value p ⦵ = 10 5 Pa (= kPa = 1 bar) is recommended by IUPAC, although prior to the value atm ( kPa) was used.
