What is an oxidation reaction
A reaction in which an atom loses 1 or more electrons.
the attachment between atoms resulting in atoms sharing one or
more pairs of electrons
What is the basic unit of chemistry
An electrolytic cell is made with zinc and aluminum electrodes Which of the following happen at the cathode of this cell
Aluminum is reduced.
Zinc ions are formed.
What can be said about a redox reaction that has a positive potential
. The reaction will be spontaneous.
How do periodic trends illustrate stability and change in chemistry
Periodic trends illustrate how some elements are very reactive
while others are stable.
What happens to the anode in an electrochemical cell
What will form a spontaneous redox reaction between two elements
The element with the greater reduction potential is the one that
is reduced.
What is the standard cell notation of a galvanic cell made with aluminum and nickel
Al(s) | Al3+(aq) Ni2+(aq) | Ni(s)
What is the oxidation half-reaction for Mg s plus ZnCl2 aq --- MgCl2 aq plus Zn s
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus
ZnCl2 aq.
What is the overall voltage for a redox reaction with the half reactions Mg s -- Mg2 plus plus 2e- and Cu2 plus -- Cu s
The overall voltage for a redox reaction with the half reactions
Mg s -- Mg2 plus plus 2e- and Cu2 plus -- Cu is 76 V.
All life on earth is ultimately dependent on what
