Since the barium ion will be isoelectronic to the nearest noble gas, which is xenon, the electronic configuration for Ba2+ is: [Xe]
Answer:
Six electrons.
Explanation:
A carbon atom has six protons, so it must have six electrons.
Answer:
21H deuterium (D), 31H is tritium (T), 11H is hydrogen
Explanation:
11H: it has the greatest abundance, it has only one proton (it does not have neutrons).
21H (D): it has a proton and a neutron in its nucleus.
31H (T): it has a proton and two neutrons in its nucleus.
Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).
ΔG = -nEF
ΔG = Gibbs free energy change
n = moles of electrones participated in
E = Electrode potential
F = Faraday constant
By substituting,
ΔG = -(3 mol) x 96485 A S/ mol x (-0.46) V
= + 133149.3 J
= + 133 kJ
Hence the answer is "b".
Since ΔG is a positive value, the reaction is non spontaneous reaction.
