The supplement that I chose was Nitric Oxide. This is a very up and coming supplement in the industry and although not many studies have been done on the long term effects many more gym goers are jumping on the band wagon and experiencing the benefits of it. Some history on Nitric Oxide is that it was first discovered in 1772 by Joseph Priestly‚ who called it "nitrous air‚" nitric oxide was first discovered as a colorless‚ toxic gas. Unfortunately‚ the classification of toxid gas and air pollutant

In this experiment‚ we have silver oxide and by using a bunsen burner‚ we will drive off all of the oxygen in the compound. We will do this by heating the silver oxide until the substance’s mass stays constant to know when all of the oxygen possible has been driven out. This process will occur through a series of heating and remassing. Silver oxide has many uses from batteries to military purposes. In a silver-zinc battery‚ silver oxide acts as the cathode and zinc as the anode. This battery is

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

Working out the Formula of Magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Apparatus Googles

other polar molecules will be. The next two alcohols were ethanol and propanol which followed the predicted pattern at 13.2 ºC and 5.3 ºC respectively. Butanol had the smallest change in temperature‚ 2.5 ºC which indicates much less evaporation. This leads to believe that butanol has the strongest intermolecular forces of the 4 alcohols tested. This is supported by the fact that butanol is the largest of the four‚ and has the most electrons‚ and therefore is the most polarizable. Interestingly‚ water
