Hydrogen sulfide

The noble gases are the group of elements which are like no other elements. The noble gases are the elements grouped as the last group, group 18. These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element…

The images a MRI machine actually present are the water molecules that make up most of our bodies systems and organs. Water molecules consist of oxygen and hydrogen atoms, the core of which is a nucleus, a single proton. The protons have a basic property called nuclear spin as well as an electrical charge which makes them act like little magnets. When the magnetic field makes the spinning protons wiggle, the stronger the magnetic field, the faster the wiggle. Nuclei wiggle at roughly 50 million…

The D-glucose serves to reduce the silver from Ag1- to Ag1+. The sodium citrate first reduces Ag1+ to Ag, and then functions to bind with the particle surface of silver nitrate particles to allow them to interact. Finally, silver nitrate can aggregate. The silver nitrate combined with D-glucose, sodium citrate, and heat forms an aggregate. The citrate binds with the particle coating and dispels the repulsion between silver nitrate nanoparticles. The nanoparticles then form an aggregate-- a loose…

This lab was conducted to find the key differences between the quantity of heat (q) and ∆H of a substance. Different masses of substances CaCl2 and NH4NO3 were dissolved in water to see how changing mass impacts the q and ∆H of a substance. When the two substances dissolve, they become ions. CaCl2 dissolves in a reaction of: CaCl2 Ca2+aq + 2Cl1-aq while NH4NO3 dissolve in a reaction of: NH4NO3 NH41+aq + NO31-aq . As shown in these reactions, when ionic compounds dissolve in water, they break…

happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even diseases. In fact, the human body is composed of 65% Oxygen, 18% Carbon, 10% Hydrogen, 3% Nitrogen, 1.5% Calcium, and in smaller amounts of several other elements. Bones make up the skeleton of the human body. They are composed of a collagen rich mixture of calcium and phosphate, which are both elements located on the…

Acid forming elements are chlorine, phosphorus, and sulfur (different from alkaline-forming elements). These elements are the primary element in foods containing moderate to large amounts of protein (except for milk and a few other dairy products). I decided on using peanut oil because peanuts yield an acid, thus they contain acid-ash. Acid-ash residue is inorganic radicals that form acid ions in the body, causing lower pH making the urine more acidic. Acid urine favors the excretion of kidney…

The objective of this experiment was to study the stereochemistry of the borohydride reduction of camphor. Sodium Borohydride is a reducing agent that is able to reduce ketones and aldehydes. In this case, camphor, which contains a ketone, was reduced with sodium borohydride. Reduction of a carbonyl with sodium borohydride occurs when the hydride ion adds to the carbonyl carbon, breaking the C=O bond and creating a new C-H bond. When the reduction occurs, the hydride transfer will occur on the…

Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are…

Oxyhemoglobin Dissociation Curve A oxyhemoglobin dissociation curve is a tool used to show the relationship between the saturation of oxygen and the partial pressure of oxygen. It directly tells us how a person own body is utilizing oxygen intake, how carbon dioxide levels are being regulated, as well as how efficient the hemoglobin in our body binds and release oxygen molecules to the appropriate tissues that require it. Normally the oxygen that our tissues need in order to function properly…

Problem Statement: How do different amounts of soil affect the pH of water? Is the relationship the same for different types of soils? Background: PH is a measurement of how many ions of hydrogen are found in a solution. The pH scale measures how alkaline or acidic an object is. The scale has numbers ranging from zero (which are considered the most acidic) to fourteen (the most alkaline, otherwise known as the most basic). Pure water has a pH of seven, however most water, either from the tap or…
