Answer the following question given this paragraph: Common acids and the polyatomic anions derived from them have their own names and rules for nomenclature. The nomenclature of acids differentiates between oxoacids, in which the H+ ion is attached to an oxygen atom of a polyatomic ion, and acids in which the H + ion is attached to another element. Carboxylic acids are an important class of organic acids. Ammonia is an important base, as are its organic derivatives, the amines. Q: What class of acids do carboxylic acids fall under? Choices: - hydrochloric acids - inorganic acids - carbolic acids - organic acids A:
organic acids
Answer the following question given this paragraph: Break down some substances in food that cannot be digested, such as fiber and some starches and sugars. Bacteria produce enzymes that digest carbohydrates in plant cell walls. Most of the nutritional value of plant material would be wasted without these bacteria. These help us digest plant foods like spinach. Q: What produces enzymes that digest carbohydrates in plant cell walls? Choices: - pollen - protists - algae - bacteria A:
bacteria
Q: Answer the following question given this paragraph: The Earth, Moon and Sun are linked together in space. Monthly or daily cycles continually remind us of these links. Every month, you can see the Moon change. This is due to where it is relative to the Sun and Earth. In one phase, the Moon is brightly illuminated - a full moon. In the opposite phase it is completely dark - a new moon. In between, it is partially lit up. When the Moon is in just the right position, it causes an eclipse. The daily tides are another reminder of the Moon and Sun. They are caused by the pull of the Moon and the Sun on the Earth. Tides were discussed in the Oceans chapter. Q: In what phase is the moon brightly illuminated? Choices: - crescent - new moon - blue moon - full moon A:
A: full moon
Question: Answer the following question given this paragraph: Oxygen has an oxidation state of -2 in most of its compounds. Oxygen is the second most electronegative element, so it also tends to be assigned all shared electrons. Exceptions include O 2 (oxidation state = 0), peroxides, in which two oxygen atoms are connected by a single bond (oxidation state usually = -1), and any compound in which oxygen is bonded to fluorine (pretty rare and reactive). Q: What is the name of the second most electronegative element? Choices: - nitrogen - Hydrogen - carbon - oxygen A:
Answer: oxygen

Answer the following question given this paragraph: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. Chemical cells have two electrodes, which are strips of different materials, such as zinc and carbon. The electrodes are suspended in an electrolyte. This is a substance that contains free ions, which can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Q: Batteries produce voltage through what type of reaction? Choices: - liquid - non-chemical - thermal - chemical A:
**Answer**
chemical
Answer the following question given this paragraph: Group 13 is called the boron group, and boron is the only metalloid in this group. The other group 13 elements are metals. Q: What is the only metalloid in group 13? Choices: - phosphorus - gallium - alluminum - boron A:
boron
