solid and vice versa. Fusion is the change of state from a solid to a liquid at the same temperature. The opposite of fusion is freezing—a liquid changes into a solid. After a while‚ some of the particles move so fast that they break free of the crystal lattice (which keeps a solid solid)‚ and the lattice eventually breaks apart. Therefore‚ I like physical changes more than chemical changes because of how liquids can become solid and vice versa. I like physical changes more than chemical changes

If you own glass vases you will want to make sure that they stay clean and Glass Vases 3sparkly. Over a period of time even a crystal glass vase can get dirty and pretty soon it will get foggy and less transparent. Instead of being able to appreciate the beauty within you’ll only be seeing dirt stuck to the glass surface. To prevent this‚ here are three different ways you can keep your glass vase clean. A Little Salt and Vinegar Vinegar is a very potent acid so you’ll need a little salt to dilute

solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ the limiting reagent Aniline and the percent yield of 96% was obtained. Introduction: This experiment involves four functional groups common in organic chemistry. The substrate (reactants)

1.) How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? The way the fluted filter paper is folded hastens filtration because it increases the surface area of the filter paper‚ giving the solution more area to go through. A piece of wire is placed to avoid build-up of pressure‚ and easily pour the solution without spilling. 2.) Enumerate 2 techniques that can help
