What is the maximum number of electrons in an atom that can have the following quantum numbers?
grigory [225]

We have to get the maximum number of electrons in an atom that can have the given quantum numbers.

(a) The maximum number of electrons in an atom that can  have quantum number n = 5, l = 3, m_{l} = +3 is 2 (two).

(b) The maximum number of electrons in an atom that can  have quantum number n = 3, l = 1, m_{l} = -1 is 2 (two).

Here, n= principal quantum number, l= azimuthal quantum number and m_{l}= magnetic quantum number.

l= 0 to (n-1) and m_{l}= -l to +l including 0.

(a) n = 5, l = 3, m_{l} = +3, this set of quantum number represents one 5f orbital which can contain maximum two electron of opposite spins.

(b) n = 3, l = 1, m_{l} = -1, this set of quantum number represents one 3p orbital which can contain maximum two electron of opposite spins.

How much heat is released when 10.0 grams of a substance cools 15 degrees? The specific
VLD [36.1K]

Answer:

Q = 525 J

Explanation:

Given that,

Mass, m = 10 grams

The change in temperature, \Delta T=15^{\circ} C

The specific heat of the substance is 3.5 J/g °C

We need to find the amount of heat released in the process. It can be given by the formula as follow :

Q=mc\Delta T\\\\Q=10\ g\times 3.5\ J/g^{\circ} C\times 15^{\circ} C\\Q=525\ J

Hence, 525 J of heat is released.

What happens if more product is added to a system at equalibrium
telo118 [61]

Answer:

When additional product is added, the equilibrium shifts to reactants to reduce the stress. If reactant or product is removed, the equilibrium shifts to make more reactant or product, respectively, to make up for the loss.
