Effect of different size beads on the activity of immobilised catalyse 2479 words 10 pages aim: to find out how varying the size of beads containing yeast varies the rate of activity of catalase in a fermentation reaction of hydrogen peroxide with immobilised enzymes. On the surface of liquid water, molecules are continually moving back and forth from the liquid state to the vapor state at a given temperature, there will be an equilibrium between the number of molecules leaving the liquid, and the number of molecules returning. There has been, however, much growth in the areas of polymer, environmental, and medicinal chemistry during the 20th century moreover, new specialities continue to appear, as, for example, pesticide, forensic , and computer chemistry.

There are three methods of heat transfer, conduction, convection, and radiation in conduction heat energy is past along from molecule to molecule molecules move more rapidly as they get hot and collide with neighbouring molecules passing along the energy. There are spaces between the molecules of liquid water the alcohol molecules fit between the molecules in the water solution this causes the final volume of the mixture to be less than the sum of the initial volumes. What is expository writing the purpose of the expository essay is to explain a topic in a logical and straightforward manner without bells and whistles, these essays present a fair and balanced analysis of a subject based on facts—with no references to the writer’s opinions or emotions.

There’s something very important about oil and water that you probably already know: oil doesn’t mix with water that explains why oil spills on the ocean float on the surface and why throwing water on a grease fire is just going to make everything worse. Add one drop of a dilute liquid soap solution to each cup using a pipette if there are bubbles present, make sure to get rid of them before continuing the experiment the soap in this case is used to wet the hydrophobic surface of the leaf, allowing the solution to be drawn into the leaf and enabling the leaf disks to sink in to the fluid.

Water molecules like to be next to other water molecules, so if you drop something into the soda, like mentos, it acts as a site for growth of bubbles mentos have a high ratio of surface area to volume, so there’s more places for bubbles to go, creating the fountain of fizz (newscientist.
