Below are the reduction half reactions for chemolithoautotrophic nitrification, where ammonia is a source of electrons and energy and oxygen is the terminal electron acceptor. no2- + 6e- -> nh4+ (-0.41 volts) o2 + 4e- -> 2h2o (+0.82 volts) using the information given, calculate the δe for this reaction, balance the full reaction to determine the n, the number of electrons transfered when 78 molecules of nh4+ are oxidized. finally, use the simplified nernst equation

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.
