Answer:
b) The volume of stock solution used is less than 3 liters.
Explanation:
Given:
Concentration of stock solution of NaCl, M1 = 10 M
Concentration of diluted solution of NaCl, M2 = 1 M
Volume of diluted NaCl solution, V2 = 3 L
Let the volume of stock NaCl solution = V1
Formula:
Use the dilution relation:

Based on the above equation:

Therefore, the volume of stock solution required is 0.3 L which is less than 3 L
A climograph is a dual-purpose graph, showing two different kinds of information. A bar graph shows how much precipitation a given place receives during a period of time. A line graph shows the temperature conditions for the same place during the same period of time.
Specialized proteins which function as catalysts for organic reactions are enzymes.

Step-by-step explanation:
Ammonium lauryl sulfate has the structural formula CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂OSO₂O⁻ NH₄⁺.
The long nonpolar hydrocarbon chain and the ionic sulfate end group make it a surfactant.
The ionic end tends to dissolve in water, but the nonpolar chain does not. This makes the compound an excellent <em>foaming agent,</em> so it is used in many shampoos and toothpastes.
The molecules form <em>micelles</em> in water, small spherical shapes with the polar heads outside, facing the water, and the nonpolar tails are inside.
They reduce the surface tension or the water so that, when you brush your teeth or shampoo your hair, the air bubbles are stable and do not break.
