Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents with the Iron Thiocyanate and changing the temperature‚ a new equilibrium was reached and the color changes

The first days in the lab will be used to practice with collecting bare footprints from different individuals using the bare footprint reagent cream. To get access to the lab‚ a Practical Risk Assessment must be made (see appendix I)‚ and three Health & Safety courses must be completed (see appendix II). After practicing with collecting bare footprints‚ the study starts with collecting footprints from six specific participants‚ whose footprints have already been collected by two other investigators

Discussion: For this experiment to occur‚ the limiting and the excess reagents needed to be determined. The limiting reagent was picked based upon the single displacement that was going to occur when the two substances‚ iron and copper(II)sulfate‚ were mixed together in water. Seeing that iron was going to displace copper and take its place‚ it was chosen to be the limiting reagent with the condition that if it was in excess then after the displacement was completed‚ there will be iron precipitate

result for protein is positive using the Biuret reagent. In the iodine test If the Iodine turns black or blue-black there is starch present so the test result is positive. In the grease spot test if the test results leaves a translucent mark on the unglazed paper it is positive for the presence of lipids. In the Sudan test if the globules have red dye within them the test result is positive; this means there is lipids present in this test. For the Benedicts test if the substance turns from a blue liquid

The Monsters of Christianity At first glance‚ the Epic of Beowulf and The Rule of St. Benedict appear to have little in common. In the tale of Beowulf‚ a hero seeks to fulfill his destiny by slaying multiple beasts and protecting the Danes until his fated death. On the other hand‚ The Rule of St. Benedict discusses how monks should live in a God centered community with one another. Despite their differences‚ both these medieval works are fighting vicious fiends‚ literally and figuratively‚ with

Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry
