<span>In a solution of water and ethanol, hydrogen bonding is the strongest intermolecular force between molecules. Hydrogen bonding occurs when the partially negative oxygen end of one of the molecules is attracted to the partially positive hydrogenend of another molecule.</span>
Answer:
Displacement
Explanation:
The starting point is different from the end point because the object will have moved a certain distance away. How far the object traveled is the displacement (or change in distance).
Answer:
a. molarity
e. molality
h. density
b. weight percent
g. volume percent
Explanation:
Molarity is defined as the number of moles of substance dissolved in per liter of solution (moles/Liter). It is also called molar concentration of the solution.
Molality is defined as the number of moles of substance dissolved in one kg or kilogram of solvent and its SI unit is mol/kg.
Density is defined as the mass divided by its volume.
density =mass/volume
Weight percent is defined as the division of mass of a solute to the mass of the total solution, multiplied by 100. To calculate the weight percent or mass percent, both mass of a solute and the mass of a solution is required to express the concentration of a solution.
Volume percent is defined as the ratio of the volume of the solute to the volume of the total solution multiplied by 100.
Answer:
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.Explanation:
