Answer: The potential of the following electrochemical cell is 1.08 V.
Explanation:
=-0.74V[/tex]
=0.34V[/tex]
The element with negative reduction potential will lose electrons undergo oxidation and thus act as anode.The element with positive reduction potential will gain electrons undergo reduction and thus acts as cathode.
Here Cr undergoes oxidation by loss of electrons, thus act as anode. copper undergoes reduction by gain of electrons and thus act as cathode.
Where both are standard reduction potentials, when concentration is 1M.
Thus the potential of the following electrochemical cell is 1.08 V.
Answer: About 10,200 Joules of heat is required to transform 80.0 g of solid benzene at 5.53°C into liquid benzene, also at 5.53°C.
Answer:
double replacement occurs
Answer:
undefined
Explanation:
It depends on the type of reactants carrying out the reaction.
C=Carbon
O=Oxygen
Oxygen is a diatomic molecule, so the subscript two needs to be used after the O in the formula.
C+O2->CO2
Hope this helps!
