Energetics Practical 2: To Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃

Practical Ethics H.Narayanan‚ EE Department IIT Bombay‚ Mumbai (Text of a lecture delivered on 16th Oct 2012) A dilemma faced by young people‚ usually at the stage when they leave home for the first time‚ is that rules that they have lived by thus far seem questionable. On the one hand the impulses that tempt and torment them seem natural while on the other‚ breaking rules that the parents have taught them in their childhood seems very wrong. Further‚ those who break their shackles are in danger

SEMESTER- I PRACTICAL- I VOLUMETRIC ANALYSIS The method to determine the exact amount of the substance in a given sample is termed as quantitative analysis volumetric analysis is a branch of quantitative analysis involving accurate measurement of volumes of reacting solutions. The volumetric analysis is very much in use due to simplicity rapidity accuracy and wide applicability. The reacting substances are taken in the form of solutions and made to react. The concentration of one solution is

activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases until the optimum
