what are the possible bonding between Gold colloids and Oxygen? why?
Compare the bonding within a water molecule to the bonding within a molecule of oxygen gas. Explain how the bonding within a water molecule is different from the bonding within an oxygen molecule
6.) Explain with as much detail possible why when bonding, fluorine will have a greater pull on bonding electrons compared to iodine. U 7.) Explain with as much detail possible why sodium has a larger atomic radius than magnesium, 8.) Explain with as much detail possible why phosphorus has a larger atomic radius than nitrogen. 9.) Elements are very chemically reactive in groups 1 and 7. Use the trends to explain this observation. 10.) Below are the first thru third...
5) Read 13.8 Colloids and explain why a soap molecule is able to clean grease but pure water is not
What is Gold? What is the history of Gold in different cultures? Why do we still use gold?
what is gold? why is it important?
Lewis structure for CO2 below non-bonding electrons on oxygen are not shown. What is the hybridization of C in CO2? O=C=O
Lois is studying a possible relationship between the market price of gold and industrial diamonds. She determined that in her study, x would be the market price of one ounce of gold and y would be the market price of industrial diamonds (price per carat). A random sample of six end-of -day closing prices on the New York Stock Exchange gave a sample correlation of r = 0.70. Assume that x and y are normally distributed and test the claim...
What are the possible bonding modes of ethylenediamine to a transition metal? Which is likely to be the most stable?
In proteins, the hydrogen bonding responsible for the secondary
structure of a protein generally takes place between backbone
carbonyl oxygen atoms and amide hydrogen atoms. In contrast, the
hydrogen bonding that contributes to tertiary structure generally
occurs between amino acid side chains.Two serine residues are shown below, with possible hydrogen bonds
shown in green. Which bonds depict the hydrogen bonding that occurs
between serine residues and contributes to tertiary
structure?
An acidic solution containing gold ions is electrolyzed, producing gaseous oxygen (from water) at the anode and gold at the cathode. For every 19.4 g of oxygen generated, 478 g of gold plates out. What is the oxidation state of the gold in the solution? ____________________________ -7-6-5-4-3-2-10+1+2+3+4+5+6+7
