Answer:
The angular momentum quantum number, l, describes the shape of the orbital that an electron occupies. The lowest possible value of l is 0, and its highest possible value, depending on the principal quantum number, is n - 1.
Answer:
That is the membrane of the cell
Explanation:
The cell membrane is made up of layers of protein and fat. It is made with a <em>phospholipid bilayer</em>. It allows some substances to pass into the cell while blocking others. This is known as <em>semipermeability</em>.

2 moles of NaOH dissolved in 1 litre of solution is the solution with more concentration.
Answer: Option A
<u>Explanation:</u>
Concentration of solution is the measure of the amount of solute dissolved in the solvent of the solution. So this is measured using the molarity of the solution. Molarity is determined as the number of moles of the solute present in the given amount of solvent.

In this present case, the option A gives the molarity of 2 M as

But the second option, mass of NaOH is given. So we have to determine the molarity. First we have to find the molar mass of NaOH. We know that 1 mole of NaOH will contain 40 g/mole.
1 g of NaOH = 40 g of NaOH
1 g of NaOH = 1/40 moles
So 2 g of NaOH will contain
which is equal to 0.05 moles of NaOH.
Thus, the molarity of 2 g of NaOH will be
Molarity =
=0.05 M
Thus, the option A is having higher concentration as the molarity is more for 2 moles of NaOH dissolved in 1 l of solution.
