Rethink number five.

A bottle of whiskey contains 40% alcohol by volume. This means that the whiskey contains 40 mL of alcohol

Means the whiskey contains 40 mL of alcohol in every 100 mL of whiskey

To find the answer, we need to remember the general properties and concepts related to ionic compounds, hydrogen bonding, solution behavior, solubility, and pH.

1. An ionic compound solution is a good conductor of electric current. Ionic compounds dissociate into ions when dissolved in water, allowing the solution to conduct electricity.

2. Hydrogen bonding in water accounts for water's higher than expected boiling temperature. Hydrogen bonding is a strong intermolecular force between a hydrogen atom bonded to an electronegative atom (such as oxygen in water) and another electronegative atom. These attractions result in higher boiling temperatures compared to other similar compounds without hydrogen bonding.

3. Polar compounds such as alcohol would be expected to be more soluble in water than in non-polar solvents. This is because water molecules (a polar solvent) can form favorable interactions with polar compounds, whereas non-polar solvents cannot provide similar interactions.

4. Water solutions of ionic substances that conduct electricity are called electrolytes. When ionic compounds dissolve in water, they dissociate into ions, which can carry electric charge and allow the solution to conduct electricity.

5. When a solvent is cooled, it will dissolve the same amount of solid and gas. The solubility of a solid or gas in a solvent generally decreases with decreasing temperature. However, once a solution has reached equilibrium, cooling the solvent will not affect the amount of solute already dissolved.

6. The water hardness in an area reported as 700 ppm (parts per million) total dissolved solids is the same concentration as 0.07%. To convert parts per million (ppm) to a percentage, divide by 10,000.

7. If the force of attraction between the ions in a solid is very strong, you would expect the solid to have low solubility in water. Strong ionic attractions result in slower dissolution of the solid in water, leading to lower solubility.

8. In liquid solutions, the solute can be a solid, a liquid, or a gas. A solution is formed when one substance (the solute) is dissolved into another substance (the solvent) at the molecular level, regardless of the physical state of the solute.

9. A solution with a pH of 2 is one tenth as acidic as a solution with a pH of 1. The pH scale is a logarithmic scale measuring the acidity or basicity of a solution. Each unit on the pH scale represents a tenfold difference in the concentration of hydrogen ions (H+). Thus, a pH of 2 has 10 times less hydrogen ions compared to a solution with a pH of 1.

10. An alkane with 6 carbon atoms would have 14 hydrogen atoms in each molecule. The general formula for alkane compounds is CnH2n+2, where n represents the number of carbon atoms. Plugging in n=6, we get C6H14 as the formula for an alkane with 6 carbon atoms.
