seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present. ABOVE: The Honda Clarity‚ the first hydrogen powered car to have a

relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction.

Premium Chlorine Chemical element Hydrogen
There need to be two chemicals that interact to release energy and also a fluorescent dye to accept this energy and convert it into light. Although there is more than one recipe for a lightstick‚ a common commercial lightstick uses a solution of hydrogen peroxide that is kept separate from a solution of a phenyl oxalate ester together with a fluorescent dye. The color of the fluorescent dye is what determines the resulting color of the lightstick when the chemical solutions are mixed. The basic premise

or active oxygen species are oxygen that is more energetic compared to the normal molecular oxygen. They are unstable and are formed either through loss of electrons or addition of protons. For example super peroxide anion (O2.-) and protonated per hydroxyl radical (H2 O2-)‚ hydrogen peroxide‚ H2 O2 and hydroxyl radical OH. (Smirnoff‚ 2007). . When these species are in the body‚ they become threats to cells

Abstract The enzyme peroxidase has been shown to break down H2O2. Enzymes are known to increase the rate at which a chemical reaction occurs. We looked at factors that affected the breakdown of hydrogen peroxide. These effects are the different temperatures and pH levels the enzymes were placed in. We found that the optimum‚ or best condition‚ temperature for the enzymes tested was about 22 degrees Celsius. The optimum pH level for the enzyme was 7. Introduction Enzymes are biochemical that catalyze

longevity. Hypothesis: The glow sticks will last longer when they are frozen than when they are at room temperature. Background information: Glow sticks are made of hydrogen peroxide‚ a phenyl oxalate called ester‚ and phosphorescent dye. The ester and phosphorescent dye are kept in one part of the glow stick‚ the hydrogen peroxide in the other‚ separated by a piece of glass. No chemical reaction occurs until the glass breaks‚ combining the chemicals together inside the tube. Cooling a glow stick
