An aqueous solution of a weak acid: a) contains intact molecules
b) contains only dissociated ions
c) has a ph greater than 7
d) does not have a Ka value associated with it

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Determine the empirical formula for succinic acid that is composed of 40.60% carbon, 5.18% hydrogen, and 54.22% oxygen.

Aroom with dimensions 7.00m×8.00m×2.50m is to be filled with pure oxygen at 22.0∘c and 1.00 atm. the molar mass of oxygen is 32.0 g/mol. how many moles noxygen of oxygen are required to fill the room? what is the mass moxygen of this oxygen?
