6. When aqueous solutions of table salt and silver nitrate are mixed, a white solid forms. This solid is a precipitate.
To determine this, you would need to have knowledge about the chemical reaction between table salt (sodium chloride, NaCl) and silver nitrate (AgNO3). When these two substances react, they form silver chloride (AgCl) as a solid precipitate, which is a white solid.
7. Stainless steel is an example of a solid-solid solution.
To determine this, you would need to understand the composition of stainless steel. Stainless steel is an alloy made primarily from iron, carbon, and chromium. It is a solid solution because the different components (iron, carbon, and chromium) are mixed together uniformly in the solid state.
8. A nonpolar molecule like cholesterol would be least likely to dissolve in water.
To determine this, you would need to consider the concept of "like dissolves like." Nonpolar molecules, such as cholesterol, do not have charged or polar regions that can interact with the water molecules (which are polar). Therefore, nonpolar molecules are generally insoluble in water.
9. A solution with a pH of 1 is ten times more acidic than a solution with a pH of 2.
To determine this, you need to understand the pH scale. The pH scale measures the acidity or basicity of a solution. A pH value of 1 is more acidic than a pH value of 2 because the pH scale is logarithmic. Specifically, each increase of 1 pH unit represents a tenfold change in acidity or basicity. Therefore, a solution with a pH of 1 is ten times more acidic than a solution with a pH of 2.
10. The SI unit of force is the newton.
To determine this, you would need knowledge of the SI (International System of Units). The newton (N) is the SI unit for force. Other options offered, such as pascal (Pa), atmosphere (atm), and kilopascal (kPa), are units of pressure, not force.
