Look at the diagram of a voltaic cell below. Which half reaction is associated with the cathode?

A. Ni+ (aq) + e- ---> Ni(s)
B. Ni(s) ---> Ni+(aq) + e-
C. Al(s) ---> Al³+(aq) +3e-
D. Al³+ (aq) + 3e- --> Al(s)​

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius

Iwould appreciate if someone could me.
