Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Curtis M. Franklin Thursday‚ February 14‚ 2013 ABSTRACT An ice calorimetric measurement was used to determine that a reaction involving solid magnesium metal and 1.00M sulfuric acid produces an experimental a value of ∆H = -226 ± 28 kJ/mol at 0°C. This is about 48.4% lower than the expected value reported at 25°C. Introduction Many chemical reactions exhibit themselves by exchanging heat energy‚ either be absorbing

Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

Spontaneous Human Combustion Spontaneous Human Combustion(SHC) pertains to the burning of a person’s body occurring without an outside source of ignition. The characteristics of SHC varies form different cases but most of the time evidences gathered are more likely show similar clues which we can relate to other SHC cases. Now‚ the evidences gathered are as follows; the victim is an elderly‚ the furniture around the victim stayed untouched‚ a part of the ceiling above the victim was damaged

Molar Heat of Combustion Aim: To find the molar heat of combustion for four different alkanols: 1. Methanol 2. Ethanol 3. 1-Propanol 4. 1-Butanol - And to compare the experimental value with the theoretical. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure‚ with the final products being carbon dioxide gas and liquid water.

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

Spark in I.C. Engine Abstract It is very interesting to know about complete combustion in automobile engineering‚ because in actual practice‚ perfect combustion is not at all possible due to various losses in the combustion chamber as well as design of the internal combustion engine. Moreover the process of burning of the fuel is also not instantaneous. However an alternate solution to it is by making the combustion of fuel as fast as possible. This can be done by using two spark plugs which
