Answer the following question given this paragraph: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures. Q: Higher pressures increase the solubility of what? Choices: - molecules - fuels - bases - gases A:
gases

Ques: Answer the following question given this paragraph: We will use sodium chloride as an example to demonstrate the nature of the ionic bond and how it forms. As you know, sodium is a metal and loses its one valence electron to become a cation. Chlorine is a nonmetal and gains one electron in becoming an anion. Both achieve a noble-gas electron configuration. However, electrons cannot be simply "lost" to nowhere in particular. A more accurate way to describe what is happening is that a single electron is transferred from the sodium atom to the chlorine atom as shown below. Q: Chlorine is a nonmetal and gains one electron in becoming a what? Choices: - sulfate - carbonate - atom - anion A:
Ans: anion

Answer the following question given this paragraph: Water treatment is a series of processes that remove unwanted substances from water. More processes are needed to purify water for drinking than for other uses. Q: What does water treatment do to water? Choices: - increases volume - restores bacteria - adds flavor - removes unwanted substances A:
(A).
removes unwanted substances
