Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Tin is a chemical element with the symbol Sn from the Latin word “stannum.” Its atomic number is 50 and its atomic mass is 118.71. Tin is classified in the ’Other Metals’ section which can be located in groups 13‚ 14‚ and 15 of the Periodic Table. All of these elements are solid‚ have a relatively high density and are opaque. This silvery‚ ductile metal is not easily oxidized in air and resists corrosion. Tin is usually malleable‚ but when cooled it is very brittle. It is found in many alloys

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal‚ it has historically been sometimes classified as a rare earth element‚ together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare earth and uranium compounds‚ but it is extracted from these ores in only a few mines worldwide. Because of the low availability
