Given that Cu + 2HCI Cu2+ + 2CI- + H2(g) has an overall reduction potential of –0.34 V, what is a valid prediction about how thi
s reaction works? The reaction is not spontaneous and will require energy to proceed. The reverse reaction would require energy input in order to occur. The half reactions would both occur spontaneously. The reaction is not spontaneous, and it is impossible to make it occur.
The first fossils were marine reptiles called plesiosaurs. They were found on Seymour Island in 1982. The first dinosaur fossil was an ankylosaur, found on James Ross Island in 1986.
