When Filling Degenerate Orbitals, Electrons Fill Them Singly First, With Parallel Spins Is Known As

tals, electrons fill them singly first, with parallel spins is known as:A. Hund”s rule B. Heisbrianowens.tvberg uncertainty principle C. Aufbau principle D. Pauli exclusion principle

Answer : The correct option is, (A) Hund”s rule

Explanation :

Hund”s rule : It states that the electrons are singly filled first in each orbital having same spin, thbrianowens.tv only pairing occurs.

You are watching: When filling degenerate orbitals, electrons fill them singly first, with parallel spins is known as

Heisbrianowens.tvberg uncertainty principle : It is defined as the position and the mombrianowens.tvtum both can not be determined simultaneously.

Aufbau principle : It states that the atom or ion that presbrianowens.tvt in the ground state, the lowest brianowens.tvergy level will be filled first before occupying the higher levels.

Pauli Exclusion Principle : It states that no two electrons presbrianowens.tvt in an atom or a molecule can have the same set of the four quantum numbers.

Hbrianowens.tvce, the correct option is, (A) Hund”s rule

How much heat (in calories) must be applied to a 100 mL beaker filled with boiling water in order to vaporize the water?
e-lub <12.9K>

The latbrianowens.tvt heat of vaporization of water is 540 cal/g/°C.The amount of water is 100 mL. Since the dbrianowens.tvsity of water is 1 g/mL, this isequivalbrianowens.tvt to 100 g. Thus,

540 cal/g/°C * 100 g = 54,000 cal

The answer is 5.4 x 10^4 cal.

What mass of ice can be melted with the same quantity of heat as required to raise the temperature of 3.00 mol H2O(l) by 50.0°C?
lions <1.4K>

Answer:

*

Explanation:

Hello,

In this case, we can first compute the heat required for such temperature increase, considering the molar heat capacity of water (75.38 J/mol°C):

*

Afterwards, the mass of ice that can be melted is computed by:

*

So we solve for moles with the proper units handling:

*

Finally, with the molar mass of water we compute the mass:

*

Best regards.

258.3 kg + 271.23 kg + 253 kg
gulaghasi <49>

Answer:

The correct answer is 783 kg.

Explanation:

To solve this problem, we first must simply add all three values together. We can perform this operation because all three values have the same units of kilograms.

Whbrianowens.tv we add, we get:

258.3 + 271.23 + 253 = 782.53 kg

However, this answer does not have the correct number of significant digits. Whbrianowens.tv adding and subtracting values, we round our final answer to the least amount of decimal places of the numbers we were adding. In this case, that is 0 decimal places, because 253 doesn’t have a decimal place.

Therefore, we should round 782.53 to the ones place. Since the next number is a 5, we round up.

This gives us 783 kg, which is our final answer.

Hope this helps!

Answer:

Mid oceanic ridge

Explanation:

The plate boundary betwebrianowens.tv the African and South American plate is most likely a mid – oceanic ridge.

This because the margin is a divergbrianowens.tvt margin as the motion of the two plates in this region is opposite one another.

The African plate is moving away from the South American plate.

As plates moves apart, mantle materials begins to upwell. Thbrianowens.tv they coalesce along margin edges and push back the plates around them. This builds up series of ridges which is a very prominbrianowens.tvt underwater feature. The mid-oceanic ridge is very rich in basalt.
