Report of Density Determinations Density is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment‚ we will determine the mass and volume of each object and then we will calculate the ratio—the density. In the first part of the experiment‚ we should measure the density of some irregularly shaped chunks of rock. The Weight of rocks is 18.769g

The term distance determination corresponds with Forensic Gunshot Residue Distance Determination Testing. Distance determination is the process of determining the distance a firearm was shot from its intended target. The determination process requires the firearm to be test fired from various distances to compare gunshot residue (GSR) patterns made during the test and compared to the ones made on the target. Often times the request for distance determination occurs resulting in the death from a shooting

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen
