Answer:
A.) 1
Explanation:
Propane only exists in one conformation. It does not have enough carbons to form branches, and there are only hydrogens attached to each carbon. Furthermore, there is no way to twist the carbon or change its orientation (ex. cis- and trans-) to result in a different structure of propane. There is no other way to represent the molecule without drawing a different molecule.
Answer:
pH = 13.18
Explanation:
pOH = -log[OH-] = -log(0.15) = 0.82
pH + pOH = 14
pH = 14 - 0.82 = 13.18
I had the same question, it's most likely B.
The liquid will stop converting into vapor. This process is to balanced the amount of substance of both phases inside the flask.
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
