Answer:
C. Aluminum Nitrate (Al(NO3)3)
Explanation:
This is because, when Aluminium nitrate dissolves in water, it dissociates to form four ions ( one aluminium ion and three nitrate ions ). Since colligative property depends on number of particles or ions present ( roult's law ), this will create much effect.
Answer:
D) 5.36 hours
Explanation:
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Also, copper will produce 2 electrons. So, out of 5 moles of copper, 10 moles of electrons will be produced.
So,
Charge on 10 mole of electrons =
To calculate the time required, we use the equation:
where,
I = current passed = 50.0 A
q = total charge =
t = time required = ?
Putting values in above equation, we get:
Converting this into hours, we use the conversion factor:
1 hr = 3600 seconds
So,
Hence, the amount of time needed is 5.36 hrs.
