b) What are the molecular shapes for each carbon and the hydroxyl oxygen?
what is the molarity of a solution made when you dilute 35 grams of sodium carbonate to a volume of 3400 ml?
On the obtained mass-spectra you got in the expected parent-ion mass region two adjacent lines with almost the same abundance (m/z=258 -100%, and m/z=260 -97%). Fragments do not show any adjacent abundant lines. What conclusion can you derive from..
The four properties that describe a gas are temperature, pressure, volume, and molar amount. Give specifics. If you increase the pressure, what happens?
