In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the ; the chemical change that occurs at this electrode is called . Group of answer choices cathode, reduction anode, oxidation anode, reduction cathode, oxidation cannot answer unless we know the species being oxidized and reduced.

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?

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
