Ice Calorimeter Determination with Mg
Ice Calorimeter Determination with Mg June 18th 2013

Abstract: This experiment determines the amount of energy needed to melt ice. A spontaneous increase in enthalpy produce by combining 0.2036g Mg and 5.00mL H₂SO₄, ice was melted and readings were taken by using an ice calorimeter. Readings were taken before during and after the reaction were completed. The data taken shows a value of -405 KJ/mol while the theoretical value was -483.7 KJ/mol. Calculating the experimental value taken with the actual theoretical value it shows a 16% error in the experiment. A possible explanation for this error could be due to heat escaping the open test tube during the Mg reacting with H₂SO₄. Data: Table 1 The fall of H₂O in the Ice Calorimeter Time (s) | Volume (mL) | 0.0 | 9.00 | 30.0 | 8.89 | 60.0 | 8.85 | 90.0 | 8.80 | 120.0 | 8.78 | 150.0 | 8.75 | 180.0 | 8.73 | 210.0 | 8.73 | 240.0 | 8.71 | 270.0 | 8.69 | 300.0 | 8.67 | Table 2 The decrease in H₂O in the ice calorimeter during the Reaction Enthalpy of Mg and H₂SO₄ Time (s) | Volume (mL) | 330.0 | 8.50 | 360.0 | 8.30 | 390.0 | 7.50 | 420.0 | 6.72 | 450.0 | 6.00 | 480.0 | 5.45 | 510.0 | 5.07 | 540.0 | 4.63 | 570.0 | 4.35 | 600.0 | 4.05 | 630.0 | 3.83 | 660.0 | 3.60 | 690.0 | 3.40 | 720.0 | 3.27 | 750.0 | 3.15 | 780.0 | 3.03 | 810.0 | 2.95 | 840.0 | 2.87 | 870.0 | 2.81 | 900.0 | 2.75 | 930.0 | 2.70 | 960.0 | 2.66 | 990.0 | 2.57 | 1020.0 | 2.51 | 1050.0 | 2.48 | 1080.0 | 2.45 | 1110.0 | 2.40 | 1140.0 | 2.38 | 1170.0 | 2.35 | 1200.0 | 2.32 | 1230.0 | 2.30 |

Calorimetry is the measurement of the quantity of heat exchanged during chemical reactions or physical changes. For example, if the energy from an exothermic chemical reaction is absorbed in a container of water, the change in temperature of the water provides a measure of the amount of heat added.…

All chemical reactions are processed through energy exchanges. Chemical reactions either absorb energy or release energy into their surroundings. In thermodynamics, endothermic reactions absorb energy where exothermic reactions release energy. In this experiment, we will be observing the chemical reactions that occur when a specific liquid is combined with a specific solid. We will measure the temperature of the liquid before the solid is added. Then we will measure the temperature of the liquid after the solid is added. We, then, will record the results, graph the temperature changes if any, and draw a conclusion whether the reaction is endothermic or exothermic reaction.…

The experiment yielded an exothermic reaction. The calculated enthalpy was far less than the theoretical. The cause of this is a lower heat transfer than the theoretical transfer. This can be caused by heat loss from the calorimeter outwards or not letting the reaction to fully take place.…

The purpose of this lab is to determine an accurate time when the ice completely melts and the water starts to boil. The problem is which type of temperature change will result from heating ice to liquid, then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time.…

In the second part of the activity, use the Temperature Sensor to measure the temperature change while ice melts in warm water. Use DataStudio or ScienceWorkshop to record and display the temperature data. Measure the amount of ice that melts. Use your measurements of the change in temperature and the amount of ice that melted to calculate the Heat of Fusion for ice. Compare your calculation for the Heat of Fusion for ice to the accepted value for the Heat of Fusion.…

Experiment one is in support of the conservation of energy pertaining to chemicals because heat energy was released when magnesium (Mg) and hydrochloric acid (2 HCl) to create magnesium chlorine (MgCl₂) and hydrogen (H₂). this reaction was exothermic because heat was produced in the process and released into the surroundings. The energy did not disappear in the reaction as it was clearly released from the substance. Therefore, the law of conservation of energy was in effect during the entirety of this…

This experiment is to calibrate a constant pressure calorimeter to experimentally determine a series of heats of reaction that will be used to predict the enthalpy of reaction for another reaction using Hess’ Law and to determine heats of dissolution for a number of ionic salts that will be used to predict lattice energy again by using Hess’ Law. Heat may increase during experiment and undergo exothermic reaction.…

When looking back on military history over the past two hundred years, it is tempting to argue that battles and entire wars are exactly as they seem. This common problem is readily found in two wars fought in the 1860s: the American Civil War (1861-1865) and the Austro-Prussian War (1866). However, while it is easy to consider the American Civil War as simply a war fought by the Union to maintain territorial integrity throughout the relatively young United States, and the Austro-Prussian War as merely the “middle” war of the three wars of German Unification meant to expand “German” territory, this is not the case. In reality, the American Civil War and Wars of German Unification (as opposed to simply the Austro-Prussian War), when compared through the lenses of military, socio-political, and personal factors, are in fact quite similar and if one compares these two series of events under the assumption that the Wars of German Unification were in fact driven by the desire to found a unified German state, one can readily come to the conclusion that the American Civil War was also a war fought to establish, as opposed to maintain, a unified American state. However, before one can start comparing the two series of events, it is necessary to point out the inherent differences between the two that makes a comparison between the two somewhat thornier to defend.…

In the graph, you can see that as the temperature increases more energy is needed to heat the water. When the temperature hits the latent heat of fusion, the temperature stops rising as the energy is being used to change the state of water. This also happens when the latent heat of vaporisation…

Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change.…
