Answer:
Potential energy = 441 N
Explanation:
Given:
Mass M = 15 kg
Height = 3 m
Find:
Potential energy
Computation:
Potential energy = mgh
Potential energy = (15)(9.8)(3)
Potential energy = 441 N
Answer:
Faraday's constant will be smaller than it is supposed to be.
Explanation:
If the copper anode was not completely dry when its mass was measured, mass of the copper must be heavier than it should have been. Hence, the calculated Faraday’s constant would be smaller than it is supposed to be since when calculating Faraday’s Constant, the charge transferred is divided by the moles of electrons.
Answer:
1)
Explanation:
Fe+2 + 2e -> Fe
The element that is reduced gains electrons. In this case Fe is gaining electrons
Answer:
i believe it's C.
Explanation:
if it's wrong i apologize, if you are looking for an "Extensive tabulation of absorption coefficients of heated air including both molecular and atomic contributions" the equation can be used to calculate that step
