Now that we’ve established that benzophenone is largely nonpolar‚ it makes sense to say that it is insoluble when mixed with water due to the fact that water is a very polar molecule

Is the Purpurin Extract from the Madder Plant a Viable Alternative to the Cobalt Used in Lithium-ion Batteries? In our modern world today‚ mankind’s surge in technological advances has made batteries a ubiquitous necessity in our daily lifestyles. The most popular form of battery is the lithium-ion (Li-ion) battery (Brain)‚ which is used an array of devices ranging from laptops and cellphones (Brain) to electric cars (Puiu). However‚ there is a need at the moment to develop a more sustainable

This paper is the first to indicate antiemetic activity of the methanolic extract compositions of A. julibrissin flowers and its protective effect on mitochondria disruption induced by retching in brain of the young chickens. Nausea and vomiting are the symptoms of drug side effects‚ different disease and defenses responsive against poisoning. Recently‚ extensive researches have led to use of medicinal plants as a safe and reliable source of drugs with low or lack of toxicity and side effects [22

The Reaction: Aniline (C6H5NH2) + acetic anhydride (C4H6O3) Acetanilide (C8H9NO) + acetic acid (C2H4O2) Results and Discussion: Amines can be treated (Acylated‚ adding a Carbonyl and losing a proton) using Acetic Anhydride as a source of an “Acyl” group to form an Amide. The Synthesis of Acetanilide (an Amide) through a Nucleophilic Acyl Substitution (addition / elimination) reaction between Aniline (an Amine) is acting

This lab report recaps the procedure and results of the lab. The chemical process studied in this lab was reduction‚ the process of reducing the number of bonds to oxygen and increasing the number of bonds to hydrogen. Other chemical processes included in the lab were recrystallization‚ melting point‚ and extraction

Experiment # 45: Benzocaine Abstract The local anesthetic‚ benzocaine‚ was synthesized via the esterification of p-aminobenzoic acid with ethanol. The percent yield of crude product was determined to be 21% and the melting point was recorded at 86.2°C ± 0.2°C‚ with a 6.3% error from 92°C‚ the literature melting point of pure benzocaine. The crude product was then recrystallized to improve the purity of benzocaine and 57.4% was recovered. The new melting point range was measured at 89.1°C ±

Radiations of GSM Base Station Antenna And Its Health Consequences- A Research conducted in Nigeria In Nigeria 98% of Global System for Mobile (GSM) base stations (cell sites) are sited within 20 meters from residential‚ offices‚ schools‚ business buildings. Cell phone antennas emit microwave frequencies‚ which are non-ionizing radiation. A research was conducted by measuring field data of radiation from GSM base antennas in Nigeria for supporting evidence public health risks from gsm radiations

Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid
