Q: Some compounds containing hydrogen are members of an important class of substances known as what? Read this paragraph and choose the correct option from the provided answers: Binary Acids Some compounds containing hydrogen are members of an important class of substances known as acids. The chemistry of these compounds is explored in more detail in later chapters of this text, but for now, it will suffice to note that many acids release hydrogen ions, H+, when dissolved in water. To denote this distinct chemical property, a mixture of water with an acid is given a name derived from the compound's name. If the compound is a binary acid (comprised of hydrogen and one other nonmetallic element): 1. The word "hydrogen" is changed to the prefix hydro2. The other nonmetallic element name is modified by adding the suffix -ic 3. The word "acid" is added as a second word. Choices: - proteins - ions - bases - acids A:
(A).
acids

Q: The acidity of a solution is typically assessed experimentally by measurement of its what? Read this paragraph and choose the correct option from the provided answers: The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4). Choices: - mass - density - color - ph A:
(A).

Q: A group of atoms that results when one hydrogen atom is removed from an alkane is referred to as what? Read this paragraph and choose the correct option from the provided answers: An alkyl group is a group of atoms that results when one hydrogen atom is removed from an alkane. The group is named by replacing the -ane suffix of the parent hydrocarbon with -yl. For example, the CH3 group derived from methane (CH4) results from subtracting one hydrogen atom and is called a methyl group. The alkyl groups we will use most frequently are listed in Table 12.4 "Common Alkyl Groups". Alkyl groups are not independent molecules; they are parts of molecules that we consider as a unit to name compounds systematically. Table 12.4 Common Alkyl Groups. Choices: - chloride group - hyrdrogen group - nitrate group - alkyl group A:
(A).
