The answer to the question is "B. Roman Numerals"
The ability of a liquid to flow up a narrow tube which is unassisted against the gravity of the attraction between molecules of the same substance. The curvature which is of the surface of a liquid at the interface with the container, the attraction between dissimilar molecules for the resistance of a liquid to flow the elasticity of surface layer of liquid because of the liquid trying to minimize its surface area.
Answer:
the tendency of some atoms in molecules to attract electrons more than their accompanying atom.
Explanation:
Answer:
1.13 M
Explanation:
Given data
- Mass of luminol (solute): 15.0 g
- Volume of solution = volume of water = 75.0 mL = 0.0750 L
- Molar mass of luminol: 177.16 g/mol
The molarity of the stock solution of luminol is:
M = mass of solute / molar mass of solute × liters of solution
M = 15.0 g / 177.16 g/mol × 0.0750 L
M = 1.13 M
