Answer: You need the mass of the bat and the length in some-type of units.
Explanation:
We have to predict the potential, whether reaction is spontaneous or not, direction of electron flow, gain/loss of mass at electrode.
The correct answers are:
The reactions are Al(s) → Al³⁺(aq) + 3e⁻ and Zn²⁺(aq) + 2e⁻ → Zn(s). The standard electrode potential for Al/Al³⁺ is +1.18 volts and that of Zn²⁺/Zn is -0.76 volts.Zn²⁺/Zn cathode and Al/Al³⁺ is anode.
(a) Cell potential= Cathode potential - Anode potential
Cell potential= E°(Zn²⁺/Zn) - E°(Al/Al³⁺)
Cell potential= (-0.76- 1.18) volts= -1.94 volts.
(b) As E° value is negative, ΔG° is positive. Hence, the reaction will not occur spontaneously.
(c) Electron will flow from anode to cathode.
(d) Anode (Al/Al³⁺) will lose mass and cathode (Zn²⁺/Zn) will gain mass.

Answer:
Electrons orbit the nucleus.
Answer:
56.8 g
Explanation:
Your first conversion factor is the molar mass of H2O to convert from grams of water to moles. Your second conversion factor is the mole ratio of 2 mol C2H10 for every 10 mol H2O. Your last conversion factor is the molar mass of C2H10 to convert from moles back to grams.
150. g H2O • (1 mol H2O / 18.02 g H2O) • (2 mol C2H10 / 10 mol H2O) • (34.1 g C2H10 / 1 mol C2H10) = 56.8 g C2H10
