Bacon‚ Toast‚ Sodium Nitrate and Potassium Bromate For Breakfast Samuel Martino Have you ever looked at the ingredients on the side of a food package? There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

Title: Density‚ Alcohol Content and the Archimedes Principle (Performed 09/11/13) Report submitted by: Purpose: Part I was to examine three different objects of the same material in order to identify the type of metal. We used the water displacement method and the buoyancy method according to Archimedes Principle. Part II was to find the density of ethanol by mass. We used a 25.0mL graduated cylinder and a 25.00mL volumetric flask to measure the volume. We used two different pieces of glassware

The mass of urea was normalized so that it could become the equivalent of what it would’ve been in the larger solvent as numbered in Data Table 4. There wasn’t much difference between the corrected number of moles and grams of urea and the amount of urea used originally used in the experiment‚ so the ammonium chloride will be primarily compared to the corrected amount of urea to make sure that the amount of solvent is equal. Graph 1 and 5 and Data Table 2 show that the mass of solutes were overall

tropical seas (L. Kannan‚ T. Thangaradjou). They grow and reproduce sexually being continuously submerged under water. They do not require contact with air‚ and the reproductive cycle with flowering and pollination is completed under water. Seagrasses have a number of adaptations to the submerged life form (Borum et al‚ 2004). Thalassia hemprichii is common on mud-coral-sand or coarse coral-sand substrates‚ in sheltered habitats in the Philippines. The plant has been observed growing from the base
