Answer:
the total electron that can be in the n=4 orbital is 32
Explanation:
it is because the formula is 2n^2,if n=4then it is 2(4)^2=32
Answer:
See explanation
Explanation:
The p orbital is threefold degenerate. This implies that the p-sublevel is composed of three orbitals; px, py and pz.
According to Hund's rule, electrons occur singly when filling degenerate orbitals before pairing takes place. Since the three orbitals are degenerate, any of px, py or pz may be first filled.
If one lobe of any of the px, py or pz is first filled, the next electron must go into the next degenerate orbital. When all are filled, pairing of electron spins may now begin.
Answer:
Explanation:
Hello,
In this case, the reaction between sodium and ammonia is:
Thus, as we know the initial masses of both sodium and ammonia, we should first identify the limiting reactant, for which we firstly compute the available moles of sodium:
And the moles of sodium consumed by 21.4 g of ammonia (2:2 mole ratio):
In such a way, since less moles of sodium are available than consumed by ammonia, we can say, sodium is the limiting reactant. Furthermore, the mass of both sodium amide (39 g/mol) and hydrogen gas (2 g/mol) that are produced turn out:
Best regards.
