Determination of % Composition of Pennies Using Redox and Double Displacement (Precipitation) Reactions Introduction: Oxidation involves the gain of electrons of hydrogen or the loss of oxygen or decrease in oxidation state. If zinc completely reacts with HCL‚ then the theoretical yield of copper should be equivalent to the actual yield. Purpose: In this lab‚ we will determine the percent composition of a modern (post-1982) penny by using a strong acid to react and dissolve the zinc

Every year we celebrate National Science Day on 28th February to honour our Nobel laureate Sir Chandrasekhara Venkata Raman for his invention of the Raman effect through his experiments on the scattering of light. Nation pays tribute and expresses gratitude to Sir CV Raman and to all the scientists on this day for their genius and dedication. It is a day‚ which attracts many young minds to take up science as their career and a day to see novel scientific achievements. The basic objective of observation

Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be

This means the change had procreated. Mutated cells are seen as a possible cause of cancer. The radiation used in the study was at levels between a Specific Absorption Rate (SAR) of between 0.3 and 2 watts per kilogram. Most phones emit radio signals at SAR levels of between 0.5 and 1 W/kg. SAR is a measure of the rate of radio energy absorption in body tissue‚ and the SAR limit recommended by the International Commission of Non-Ionizing Radiation Protection is 2 W/kg. The study also measured other

Absorption Costing vs. Variable (Direct) Costing Absorption cost systems are widely used to prepare financial accounts. These systems are designed to absorb all production costs (variable or fixed) into costs of units produced. Absorption costs techniques allow manufacturing costs to be traced and allocated into product costs. There are different types of absorption costing systems: job order costing‚ process costing‚ and ABC costing. In job order costing‚ costs are assigned to products in batches

In 1928‚ Raman spectroscopy was introduced by Sir Chandrasekhara Venkata Raman an Indian Physicist‚ together with K. S. Krishnan. For this tremendous contribution in Physics‚ Sir C. V. Raman got Nobel prize in 1930. Write something about Raman signal‚ where does it come from? What are the implications of Raman? Raman is the inelastic scattering of light. The meaning of inelastic scattering is observable from the figure below. When an electron is excited by photons of applied light‚ it jumps from
