Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher

TITLE: Water Based Drilling Fluid Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and

Chromatography Lab Questions Pre-Lab Questions 1. A pencil is used rather than a pen to mark the “starting line” in step two because a pen or marker while be used to place a small dot of ink in the center of the X that is made with a pencil. 2. Capillary action is filling of pores in a solid with a liquid. Capillary action is caused by spotting or absorption and is allowed to seep or flow through. 3. The type of pen that will probably give better separation in this paper chromatography

Percussionists have a specific reputation in the music world. They’re loud. They’re immature. All they do is bang on stuff. For some percussionists‚ this generalization is spot on. These people call themselves "drummers"‚ and in doing this‚ they limit their musical capabilities to three instruments: the snare drum‚ bass drum‚ and drum set. As kids advance through school‚ the drummers get weeded out. The parts become more difficult‚ more practice time is expected‚ and the instrument variety expands
