The metal component of the given compound, CrCl3, is chromium. The number of moles per 1 g of chromium is calculated through the equation below,
n = (1 g Cr)(1 mol Cr/51.996 g Cr)
n = 0.0192 mol Cr(3 electrons/1 mol Cr)
n = 0.0577 e-
Determine the number in charge by multiplying with Faraday's constant,
C = (0.0577 mol Cr)((1 F/1 mol e-)(96485 C/ 1F)
C = 5,566.87 C
Then, calculate time by dividing the charge with the current,
t = 5566.87 C/1.5 A
t = 3711.25 minutes
t = 61.84 hours

Protons and neutrons exist within the neucleus, while electrons do not.
Look on the periodic table it should be above atomic symbol
Answer:
The external atmospheric pressure decreases and so does the boiling point of the liquid.
Explanation:
We know that pressure decreases with height. Thus atmospheric pressure decreases at higher elevation.
The implication of this is that, if I take a liquid from sea level to a higher elevation, the external atmospheric pressure on the liquid will decrease and so does its boiling point.
Hence, the liquid boils at a lower temperature when placed at a higher elevation. For this reason, the boiling point of a liquid is lower on the mountain.
The effects of sinkholes vary based on where and how they were formed.
When naturally formed on land, they will change the topography of the surroundings, cause nothing but minor issues, if any issue at all.
When formed on highly populated areas, though, they can cause a lot of damage to humans and properties in the region. Damage caused to the base of a building might be a very serious problem.
Toxic chemicals can also come up through sinkholes.
