theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed together

ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20

Compare and contrast the structure and bonding in Ionic‚ Covalent and Metallic species. Relate the structure and bonding to the properties of the species. Ionic bonding is usually formed between a metal and a non-metal‚ Covalent between two non-metals and Metallic between two metals. Ionic Bonding; Ionic bonds tend to form between metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

During the late classical period from 206 B.C.E to 476 C.E.‚ the Roman Empire controlled the Mediterranean world and the Han Dynasty stretched from the Yellow River to the South China Sea. Although the Romans and Han empires used powerful militaries and infrastructure to control the peasants and fend off invasions‚ they differed in the structure and organization of their bureaucracies and the control that the emperors had over the governors of the provinces. In order to control their

primary objective. The experiment was divided into two parts‚ first‚ mixing two aqueous solutions of ionic compounds. The second part involved the observance of heating and combustion reactions‚ using the supplied solid elements and compounds. Experiment and Observations: The first part of this experiment involved mixing the compounds‚ provided by Hands-On Lab‚ in a 24-well plate. Aqueous solutions of ionic compounds were mixed in eight separate wells. A few drops of each solution were mixed in a well
