Hydrogen: The Fuel of The Future By: Json Why are we as Americans so afraid to change? even if it is a change for the better? the world has been using oil coal and other petroleum products to power just about everything that moves for the last 150 years. yet most cars in the united states only get 10-20 miles a gallon and even the "good" ones can get only a petty 20-50 miles a gallon. so why do we put up with the inefficiency when there are far better alternatives out there? Such as hydrogen

Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are
