Analytical chemistry calculations 1. (5 marks) Calculate the solubility product of Hg2SO4 using the following half-reactions: reduction of Hg2SO4(s) to Hg(l) and reduction of Hg22+ to Hg(l). 2. (5 marks) An electrochemical cell is constructed in which both electrodes are made of platinum, but in which one electrode is in contact […]
heptane, C7H16, is the hydrocarbon given a value of 0 on the octane rating scale for gasoline. Calculate the heat needed to raise the temperature of 170 kilograms of liquid heptane from room temperature, 21 degrees celsuis, to gaseous heptane at 121 degrees celsius. The boiling point of heptane is 98 degrees celsius. specific […]
Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressure it is found out that one volume of Cl2 reacts with three volumes of F2 to yield two volumes of the product. What is the formula of the product?

Week 6 | Discussion – Genetic Engineering The human genome project was completed in 2003. Please go to the following website to review the goals of the human genome project: http://www.ornl.gov/sci/techresources/Human_Genome/home.shtml. One of the benefits that has come from this project is that we are now able to identify the genes that can cause disease. Discuss […]
