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

Answer:
The second one
Explanation:
Gas pressure is caused by gas molecules bouncing off the container walls and each other. Every time a molecule changes direction because it hits a wall, the change in momentum results in a small push. Due to the large number of molecules involved, the pushes add up to a large amount of pressure.
Light travels in a straight line as a wave. It does not require any medium or material to travel like sound waves which means it can travel in vacuum.The speed of the light from the special theory of relativity is a constant value of 38x10^8m/second
For question two, you figure out the amount of sodium atoms on the left and right side and the amount of oxygen atoms on the left and right side
So for two it would be 4, 1, 2
For question four, you figure out the amount of atoms on each side
So for four it would be 1, 2, 1, 2
The answer is C24H42O21. Lack of hydration responses shapes covalent bonds between two monomers by the arrival of a water particle. Every monomer taking an interest in the bond discharges either a hydroxyl amass (- OH) or a hydrogen (H) for each bond shaped. Connecting four glucose monomers requires three covalent bonds. This outcome in the loss of three particles of water or six hydrogen molecules and three oxygen iotas.
