Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

Kinetics of Hydrogen Peroxide February 22‚ 2007 Chem. 1130 TA: Ms. Babcock Room 1830 Chemistry Annex PURPOSE OF THE EXPERIMENT Kinetics of Hydrogen Peroxide The major purpose of this experiment is to determine the rate law constant for the reaction of hydrogen peroxide and potassium iodide. In this experiment‚ the goal will be to try to measure the rate law constant at low acidity‚ since at low acidity‚ anything less than 1.0 x 10-3M‚ the effect of the hydrogen ion is negligible. To calculate

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

Purpose: The purpose of the lab was to investigate and demonstrate hydrogen bonding and London dispersion bonding in water and rubbing alcohol. Hypothesis: I believe water will have the greater surface tension because rubbing alcohol’s density is lower than water’s. Materials: * Water * Isopropyl alcohol (rubbing alcohol) * Pennies * Paper clips * Flasks * Cups or jars * Wax paper * Eyedropper Procedures: Part 1: Surface tension and vortex: * Fill
