Introduction Recently special attention has been given to search of new effective methods to recover platinum metals PM from different raw materials: placer platinum, metallurgy platinum concentrates, dead automobile and chemical catalysts, PM scrap, etc. Peer-review under responsibility of the Omsk State Technical University doi: Study subject Rossion ion exchange resins, consisting of nitrogen functional groups Table 1. Table 1. Characteristics of studied ion exchange resins.

Initial solutions and experimental method To study PM recovering from MMC "Norilsk Nickel" sulphate cupronickel solutions by Rossion ion exchange resins three metallurgy shop solutions were chosen. Table 2. Content of studied solutions. Results and discussions Earlier in [, 14] sorption characteristics of Rossion ion exchange resins against platinum and palladium chlorine complexes were examined and the opportunity of high copper content palladium II sorption recovery from homogeneous catalysts based on OJSC "Omsky Kauchuk" acetaldehyde was shown. References [1] M. The number of protons and electrons the atom has, and the number of electrons it has gained or lost, results in different levels of stability. A substance which is less stable, will have a shorter half-life than a substance which is more stable.

Additionally often elevated temperature and excess of nucleophiles are required. There are a few reports where use of a catalyst has not been necessary [3,4]. The same reactions fail in water. After the lightning of Ammonium dichromate, Chromium III oxide was formed while the Nitrogen and Water escaped into the atmosphere in a gaseous phase. One mole of Ammonium dichromate will give rise to one mole of 1 mole of Chromium III oxide and 1 mole of Nitrogen gas and 4 moles of Water is gaseous phase. It is debatable which product is more prominent due to steric reasons and the capability of each product to conduct in hydrogen bonding. The ortho products allows for extra stabilization due to hydrogen bonding between the alcohol and nitro group adjacent to one another.

The issue here is that these are both fairly large molecules therefore there may be a bit of steric hindrance making this a bit less. For this experiment, stereochemistry was observed by analyzing both the isomerization of dimethyl maleate and carvones. The dimethyl maleate is formed by two methyl ester groups that are connected by an alkene.

They are in a cis-conformation meaning they are on the same side of the alkene, therefore the esters are close to one another. This conformation is strained and sterically hindered due to electrons repelling each other and are enantiomers of one another. With the use of radical chemistry, the cis conformation can be changed into a trans configuration where the esters are on opposite sides of one another. Isotopes of the same element have the same amount of protons, but different amounts of neutrons. Different isotopes of the same element differ in atomic mass because of the change in number of neutrons, but still hold the same chemical properties. An ion is where an atom is missing or has extra electrons, which cause a net electric charge.

Covalent bonding happens when two elements share electrons and become bonded together. Using the combined gas law, the calculated volume of the gas at STP would be 0. If one wanted to find the volume of mole this gas at STP, then all that is required is to divide the 0. In the end, the volume of mole of the hydrogen gas produced in this experiment would be equal to Sources of Error: What could have been done is more trials to make sure. The maximum in the graph around the atomic number of iron illustrates the transition from fission to fusion. This light then travels past the flame created by an atomizer.

Polarity shared electrons get pull away difference in electrical charge at one end as opposed to the other end 2. Ionic bonding when the electronegativity differences between 2 atoms were so extreme that the electrons were pulled off 1 atom only to latch on to the atom that was attracting them A: What is an Ion? Ion is a changed atom or an atom with the number of electrons different from it number of protons 2.

Ionic bonding is the chemical bonding in which 2 or more ions are linked by virtue of its opposite charge 3. The purpose of this experiment was to see which solute, Splenda, granulated sugar, or salt, would dissolve the fastest in distilled water.
