I learned more about the molarity of aqueous solutions‚ and how that quantity‚ along with the volume of the solution‚ can be manipulated to find the exact number of moles in a given volume. In this case‚ experimenters were given aqueous solutions of NaOH and CaCl2 in known molarities and then had them react with one another to yield a precipitate of Ca(OH)2. The precipitate was filtered out of the remaining aqueous solution of stoichiometry. In our case‚ all four tests yielded more mass than should

Interhost Solutions (IHS) utilized some business plans in starting the company. The founders set clear KPIs and make use of some business frameworks. In the beginning‚ they tried to apply the Lean Start-up method‚ but they say that it was difficult for the service company to stick to it. This fact is really insightful because simultaneous experimentation such as the Lean Start-up is more effective for start-ups than focused commitment (Andries‚ Debackere‚ and Van Looy‚ 2013). Hence‚ IHS should have

the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2) A beaker 3) A cork borer 4) A Knife Safety

was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate‚ cooled slowly in an ice bath as crystals started forming out. As the compound crystallizes from the solution‚ molecules of other compounds were excluded from the crystals to obtain pure acetanilide. INTRODUCTION Recrystallization‚ referred to as the second crystallization‚ is a method

objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day was reserved

In this study‚ we found that the growth of the duckweed thalli did not have a significant difference in the NP solution and the creek water solution. Although we found that the duckweed grows faster in the NP solution‚ rather than the creek water they do indeed have relatively the same mean. Overall our results supports our hypothesis. This also makes us question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in

TerraCog Case Analysis Part 1 Analysis The situation of dysfunction during meetings in TerraCog is obvious. Both the participants and the facilitator don’t play professional in the meetings and they don’t have necessary communication with others before the meeting. All these poor performances make all meetings which are described in the case study has very low efficiency and cause so much negative emotion amount team members. Primary and secondary tensions Primary tension comes from the unfamiliarity
