Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

Chemical Report The chemical I will be writing this report on is oxygen. The name oxygen comes from the Greek word “oxygens‚” which means “acid producer”. Dictionary.com defines oxygen as “a colorless‚ odorless‚ gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.” Oxygen has many uses today. First‚ oxygen is used by people‚ plants‚ and animals in the respiration process. Tanks of oxygen are used in the healthcare field to treat

exposed to sunlight the leaf splits water into hydrogen gas and oxygen gas‚ the gas can then be collected and used as fuel. Dr. Nocera’s process of “artificial photosynthesis” can more precisely be defined as solar-powered electrolysis of water (Owen‚ 2012). During the electrolysis of water energy from the sun electrochemically splits water into hydrogen gas and oxygen
