Answer:
False
Explanation:
It is important to give exact measurements.
The answer is D... It reduces bird and bat population.
It will take 9.64 minutes to deposit 1.00g of Zn metal
Convert the mass of Zn produced into moles using the molar mass of Zn.
Molar mass of Zinc = 65.38
No of moles of Zn = 1.00 ×
= 0.015 moles of Zinc
the half-reaction for the production of Zn at the cathode.
Zn²⁺ (aq) + 2 e⁻ → Zn(s)
the moles of e⁻ required to produce the moles of Zn using the stoichiometry of the balanced half-reaction.
According to the equation 2 moles of electrons will produce one mole of zinc.
0.015 × 2 mole e⁻ / 1 mole of Zn = 0.03 mol e⁻
Convert the moles of electrons into coulombs of charge using Faraday's constant.
1 F = 96485 C
0.03 × 1 F / 1 mole
= 0.03 × 96485 / 1
= 2894.55 C
the time using the current and the coulombs of charge.
5.00 A × t = 2894.55 C
t = 2894.55 / 5.00
t = 578.91 s
= 9.64 minutes

This correct option is C.
10^-2 = 0.001
8.7 * 10^-2 = 8.7 * 0.001 = 0.0087
Thus, 8.7 * 10^-2 is equivalent to 0.0087.
