Answer the following question given this paragraph: The strength of an acid depends on how many hydrogen ions it produces when it dissolves in water. A stronger acid produces more hydrogen ions than a weaker acid. For example, sulfuric acid (H 2 SO 4 ), which is found in car batteries, is a strong acid because nearly all of it breaks down into ions when it dissolves in water. On the other hand, acetic acid (CH 3 CO 2 H), which is the acid in vinegar, is a weak acid because less than 1 percent of it breaks down into ions in water. Q: The strength of an acid depends on how many of which ions it produces when it dissolves in water? Choices: - silicon - carbon - helium - hydrogen A:
hydrogen

Answer the following question given this paragraph: Monosaccharides A monosaccharide is a monomer of carbohydrates. Five monosaccharides are important in the body. Three of these are the hexose sugars, so called because they each contain six atoms of carbon. These are glucose, fructose, and galactose, shown in Figure 2.18a. The remaining monosaccharides are the two pentose sugars, each of which contains five atoms of carbon. They are ribose and deoxyribose, shown in Figure 2.18b. Q: Glucose, fructose, and galactose are hexose sugars, which contain six atoms of what element? Choices: - oxygen - hydrogen - nitrogen - carbon A:
**Answer**
carbon
