Answer:
Diamagnetic
Explanation:
Hunds rule states that electrons occupy each orbital singly first before pairing takes place in degenerate orbitals. This implies that the most stable arrangement of electrons in an orbital is one in which there is the greatest number of parallel spins(unpaired electrons).
For vanadium V ion, there are 18 electrons which will be arranged as follows;
1s2 2s2 2p6 3s2 3p6.
All the electrons present are spin paired hence the ion is expected to be diamagnetic.
Answer:
The value of Cpk is 0.83.
Explanation:
Given that,
Upper specification limits = 10 cm
lower specification limits = 8 cm
Mean = 9.5
Standard deviation = 0.2 cm
We need to calculate the process capability
Using formula of Cpk
Put the value into the formula
Hence, The value of Cpk is 0.83.
Answer:
d
Explanation:
d because the sun is in the center and everything else surrounds it
A geocentric system is a part of the astronomical theory which describes the universe. Meaning that it puts the Earth in the CENTER of the universe as a point of view for other objects surrounding it.
Answer:
2400 J
Explanation:
Latent heat: This is also called hidden heat, it is the heat that is not detectable by the thermometer.
From the question,
Q = cm.................. Equation 1
Where Q = Energy, c = specific latent heat of the liquid, m = mass of the liquid.
Given: c = 4000 J/kg, m = 600 g =( 600/1000) kg = 0.6 kg
Substitute these values into equation 1
Q = 4000×0.6
Q = 2400 J
Hence the energy required is 2400 J
