Answer:
Ionization energy : energy required to take out an electron from the valance orbital of an atom.
Electron affinity: electron affinity of an atom measures the amount of energy released when an electron is forcibly entered or pushed into the valence orbital of an atom.
Ionization energy is the energy required to make an atom into a positive ion. Electron affinity is the energy released when an atom becomes a negative ion.
ionization energy is what is required to remove one electron from a normal gaseous atom to produce a +1 anion of that atom.
electron affinity is the energy required to remove one electron from a gaseous -1 anion of an atom to produce a normal gaseous atom.
Answer:
If the pressure is increased, the equilibrium position moves in the direction of the fewest molecules of gas. This means it moves to the right in the Haber process. ... Stronger equipment is needed, and more energy is needed to compress the gases. So a compromise pressure of 200 atmospheres is chosen.
Explanation:
Answer: 42 hours
Explanation:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
According to stoichiometry:
1 mole of electrons deposit = 23 g of sodium
i.e 96500 C of electricity deposit = 23 g of sodium
Thus 23 g of sodium is deposited by = 96500 C of electricity
of sodium is deposited by = C of electricity
To calculate the time required, we use the equation:
where,
I = current passed =
q = total charge =
t = time in secods = ?
Putting values in above equation, we get:
Thus 42 hours are required.
Answer:
The larger the species, the further away from the nucleus the outer electrons are and hence the less strongly they are held. This means the bigger atoms will be more polarizable. So, the order from biggest-smallest molecules (strongest to weakest IMF) is iodine, bromine and finally chlorine.
