Answer:
The cathode of a spontaneous electrochemical cell is the cell in which metal cations undergo reduction. The electrons are supplied by the anode. Without much thought, we can conclude magnesium is much less favorably reduced than gold.
<span>Enthalpy is a state function because its change depends only on initial and final conditions.</span>
P1/T1 = P2/T2
125⁰C = 398.15 k
182⁰C = 455.15 k
1.22/398.15 = p2/455.15
p2= 1.39atm
the pressure of the gas be after the temperature change is 1.39 atm
<span>C. a carbon chain with a carbonyl group bonded to one end
</span>
Answer:
Because of the existence of isotopes.
