Acyl chloride

This experiment was performed at the University of Louisiana at Lafayette campus on March 7, 2017. Pots were prepared using 30 0.95-liter black plastic pots. Each pot was labelled sequentially from 1 to 30 along with the soil treatment it would receive, either 100% vermiculite or 90% vermiculite, and the planting density, either 1, 2, 4, 8, or 16 seeds planted. The 100% vermiculite soil treatment was then prepared by using a clean 0.95-liter black plastic pot and adding 15 pots of vermiculite to…

Examined T. californicus ability to handle high temperature stress under short-term, small exposure to high temperature, and long-term, persistant exposure to constant high temperatures. The took populations of T. californicus from 11 pools at different latitudinal gradients in a local scale. They put the specimen in petri dishes with founding adult females. They only mate one time and store the sperm so they can produce many groups of offspring. To test if inbreeding could influence the…

Much of the workflow for ceramics production remains the same over the many years this art form has been practiced. When centuries ago, a potter starting the process workflow of producing a ceramic mug (or more likely a jug), he would go to a river bed and collect the clay. Now, Angel Pottery’s supplier is currently a clay supplier in Amherst, Massachusetts. In this supplier’s factory, they use mixing augurs to produce the raw material clay. From factory to home factory, the clay bags are…

Introduction Chlorophyll absorb light energy through photosynthesis. However, light can have different frequencies, which are visible through color. This experiment seeks to measure the effects on the different light frequencies, and therefore different light colors, on the rate of photosynthesis. Also, objects appear to be the color of whatever light they do not absorb. This occurs because light frequencies which are not absorbed bounce back, creating the color appearance of an object.…

Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism. Background: When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…

Iodine is a metallic grey element found in the halogen part of the periodic table. In the early 1900s, many people in the U.S. were suffering from Iodine deficiencies which caused all sorts of health complications. The decision to add iodine to salt was made to remedy these deficiencies and the problems associated with them. Salt was picked as a host for the iodine, because of its widespread use and the ease at which iodine could be added. This decision did not come without a cost and today the…

What is Sodium cyanide? Sodium Cyanide is an inorganic Compound, it has a formula NaCN. Cyanide actually has a high affinity for metals which can lead to a high toxicity of the salt. Sodium Cyanide has a boiling point of 2,725°F (1,496°C) and it also has a melting point of 1,047°F (563.7°C). A common name for sodium Cyanide is sodium salt of hydrocyanic acid. Cyanide has an appearance of while crystalline or granular powder. This toxin releases a hydrogen cyanide gas which is…

Goggles are imperative for keeping your eyes safe in the lab. By wearing goggles you can protect your eyes from foreign items and substances from hurting them. Keeping goggles on at all times, when working with any chemical substance is mandatory, if any chemicals splash into the eyes, the eyes are protected by the goggles. The right clothing can help avoid many accidents in the lab. Wearing your lab coat can protect you from any chemicals coming in direct contact with your skin. Also,…
