Answer the following question given this paragraph: Adding a solute increases the boiling point of a pure solvent. This change can be calculated using the equation . Q: Adding a solute does what to the boiling point of a pure solvent? Choices: - no effect - silences it - reduces it - increases it A:
increases it
Answer the following question given this paragraph: The driest climates are deserts . Most occur between about 15 and 30 latitude. This is where dry air sinks to the surface in the global circulation cells. Deserts receive less than 25 centimeters (10 inches) of rain per year. They may be covered with sand dunes or be home to sparse but hardy plants (see Figure below ). With few clouds, deserts have hot days and cool nights. Q: What has hot days and cool nights, and are typically covered with sand dunes or sparse but hardy plants? Choices: - rain forest - tundra - arctic - deserts A:
deserts
Q: Answer the following question given this paragraph: Carbohydrates are biochemical compounds that include sugar, starch, glycogen, and cellulose. Sugars are simple carbohydrates with relatively small molecules. Glucose is one of the smallest sugar molecules. Its chemical formula is C 6 H 12 O 6 . This means that a molecule of glucose contains 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen. Plants and some other organisms make glucose in the process of photosynthesis. Living things that cannot make glucose can obtain it by consuming plants or organisms that consume plants. Q: Sugars are simple types of what biochemical compounds and possess relatively small molecules? Choices: - proteins - vegetables - lipids - carbohydrates A:
A: carbohydrates
Question: Answer the following question given this paragraph: The magnetic quantum number , signified as , describes the orbital orientation in space. Electrons can be situated in one of three planes in three dimensional space around a given nucleus and . For a given value of the angular momentum quantum number , there can be values for . As an example:. Q: What is the term for the number that describes an electron's orbital orientation in space? Choices: - magnetic electron number - relative quantum number - imaging quantum number - magnetic quantum number A:
Answer: magnetic quantum number

Answer the following question given this paragraph: Hydrogen bonds cause water to have a relatively high boiling point of 100C (212F). Because of its high boiling point, most water on Earth is in a liquid state rather than in a gaseous state. Water in its liquid state is needed by all living things. Hydrogen bonds also cause water to expand when it freezes. This, in turn, causes ice to have a lower density (mass/volume) than liquid water. The lower density of ice means that it floats on water. For example, in cold climates, ice floats on top of the water in lakes. This allows lake animals such as fish to survive the winter by staying in the water under the ice. Q: What bonds cause water to have a high boiling point, leaving most water on earth in a liquid state rather than in a gaseous state? Choices: - potassium bonds - carbon bonds - helium bonds - hydrogen bonds A:
**Answer**
hydrogen bonds
