List the quantum numbers associated with all of the 5d orbitals
Whitepunk [10]

Answer:

Here's what I get  

Explanation:

If the orbital is 5d, n = 5 and l=2.

mₗ = -l, -l + 1, -l + 2,  …., l

(mₛ is a quantum number for electrons)

Thus, we can have the following combinations.

\begin{array}{ccr}\mathbf{n} & \mathbf{l} & \mathbf{m_{l}}\\5 & 2 & -2\\5 & 2 & -1\\5 & 2 & 0\\5 & 2 & 1\\5 & 2 & 2\\\end{array}

That makes a total of five 5d orbitals.

The pictures below show what two of them look like.

The free energy for ATP hydrolysis in vivo is actually > the standard free energy change of -30 kJ mol-1 because ________. a.
Julli [10]

Answer:

The correct answer will be option C.

Explanation:

ATP is the energy molecule which on hydrolysis provide energy to the cells for metabolic functions.

In vitro, the standard free energy of the ATP is -30.5 kJ/mol but its value varies in the cell as the concentration of ATP and its products like ADP, AMP and Pi are unequal in a cell. The Mg2+ in the cytosol has the ability to bind ATP and ADP, as well as the time of ATP hydrolysis, differs from cell to cell, thus influencing the concentration of ATP and its products.

Thus, option C is the correct answer.
