Sodium compounds

Since suitable crystals for X-ray single crystal analysis was not obtained, to have reliable structural information, HR-TEM analysis of the product was carried out. The average size of the assembly calculated from HR-TEM measurement is found to be 2.8 nm which is in good agreement with the size of the previously reported Pd6L8 assembly where L is the non N-methylated (2.5nm, Fig. 2).9 As first step, to explore the catalytic activity of 1 in copper and phosphine free Sonogashira coupling reaction…

Research Question: How do different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid…

Introduction: In this lab, seven test tubes containing solutions in equilibrium had different stresses added to them to examine the balance in each example. The purpose of the experiment was to indentify the details of shifting in equilibrium reactions and determine how the adding of a stress can affect a reaction. A chemical reaction that is in equilibrium is reversible, where a reactants can create products and products can go back to products. Equilibrium is reached when the rate of a…

Endothermic or Exothermic? The energy changes lab was an interesting lab in which the class compared two chemical reactions, the solute baking soda and the solvent vinegar, and the solvent baking soda solution with the solute of calcium chloride to see whether the changes were endothermic or exothermic reactions. I concluded that vinegar and baking soda was the endothermic reaction and baking soda solution and calcium chloride was the exothermic reaction. I knew this because in the vinegar and…

What I have found about this experiment is some really interesting ideas and other ways to the experiment. Some other people use Sodium or other words, for Sodium on the periodic table this chemical is called “Na” other people use that to make the Elephant Toothpaste. The call it Elephant Toothpaste because it’s supposed to look like toothpaste and since it's so big and it looks like toothpaste so the first thing people thought of was Elephant Toothpaste. Is that it was so deadly and that it…

Chlorine is a chemical added to swimming pools to keep the water free of bacteria and algae. Chlorine levels in swimming pools vary based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules. This means that pool owners spend a lot of time testing and adjusting the levels of chlorine in their pools. To reduce the amount of time spent on pool maintenance, pool chemical manufacturer's created chlorine tablets. These tablets are…

We are testing different watt light bulbs and how it affects how fast the chads rise. We are using 300, 200, 100 and 60 watt lights bulbs. We are timing how long it takes for the chads to rise with each different light. Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The…

For my orthographic drawing, I created three different views of my putt putt boat. I created a top, front and side view of my boat. I created an orthographic drawing because it accurately shows the top, front and side views clearly and more precisely. I was representing a 3d object in 2 dimensions. My three views show how each side of the boat looks in detail and the accurate measurements of the boat. To create the hull, we shaped a piece of aluminum into a “pocket” by using sandpaper to sand…

sensation, muscle contraction, hormonal activity, fluid secretion, immune response and, of course, brain activity. Ion channel drugs are used to treat major cardiovascular, neurological, muscular, metabolic, and respiratory conditions. In particular, sodium channel drugs have the remarkable ability to target specific cells to control sensory or motor functions, without threatening vital processes. This selectivity allows for uses as local anaesthetic, analgesic, anti-arrhythmic and…

Limiting reactants occur in a reaction when one of the reactants runs out and there is excess of another reactant. It is important to understand limiting reactants because it allows us to adjust the amount of chemicals we need to create a product without having excess chemicals. On October 5, 2017, we completed a lab in which we determined which chemical was the limiting reactant in a reaction by adding each chemical to the excess chemical and observing which formed a precipitate. II. Data,…
