What functional group is a: double bonded O that is single bonded to another O and single bond CH3
An introduction similar to this related to the same subject with is the crystalline structures, if you can paraphrase it in a way that does not make it plagiarized then that's fine too
Magnesium metal is used as a sacrificial anode to reduce the corrosion of underground storage tanks (made of iron, more accurately steel). As a result the sacrifical metal corrodes instead of iron. Explain
Explain why the atomic mass of an atom is a decimal number and how that value was determined before being placed on the periodic table.
To account for the high electronegativity difference between hydrogen and fluorine, we reassign the orbital sites in HF in order to create an energy ladder that gives us a logical sequence for assigning electrons
The percent ionization of octylamine in a .10 M aqueous solution is 6.7%. What is the pH of the solution and the Kb of octylamine?
a sample of gas at 77 degreees celsius and 1.03 atm occupies a volume of 2.02L. What volume would this gas occupy at 107 degreees celcius and 0.789 atm.
Using the diagrams provided below, draw an atomic-scale view for the chemical species that are present in the solutions in each beaker. In your diagrams, be sure to Include all chemical species except water molecules
