more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are

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

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Mass of Zinc Determination on Galvanized Nails Introduction. In this experiment the mass of zinc on galvanized iron nails was calculated to determine the appropriate price that should be charged to coat a nail with zinc (galvanize) it. The effectiveness of gasometric and gravimetric analysis were assessed by carrying out both methods mathematically using values determined by this experiment‚ and then comparing these values using their percent differences. The mass of zinc found on each nail can

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

the previous generation used to be‚ Fishman’s evidences are more up-to-date. According to a recent Sun editorial‚ “activism has transformed from sensationalized 1960s tear-gas rallies to online petitions and Internet discussion boards” (Fishman 73). Not only Fishman‚ but also the reality tells that the time has changed. News can be spread worldwide in seconds through the Internet‚ and it can easily gather “Generation Q”‚ written by Thomas L. Friedman‚ and “The Generation of Generation Q”‚ written

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

Our Generation If you spend much time with your kids‚ you quickly realize that the next generation of teens is much unprepared to deal with the real world. They are overweight‚ lazy‚ undisciplined‚ disrespectful‚ and disobedient to their parents‚ selfish‚ self-centered‚ and completely addicted to entertainment. And that is just for starters. Their parents feed them insane amounts of sugar and high fructose corn syrup and then when they become overactive we pump them full of prescription drugs

Reaction of catalase with hydrogen peroxide AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast‚ potato or liver‚ speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogy…
