Answer the following question given this paragraph: Electronegativity Differences between Metals and Nonmetals An element's electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity ( 2.2 in Figure 7.15 "Pauling Electronegativity Values of the ") have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i. , they are oxidants). In contrast, elements with a low electronegativity ( 1.8) have electron affinities that have either positive or small negative values and small ionization potentials, so they are generally metals and good electrical conductors that tend to lose their valence electrons in chemical reactions (i. , they are reductants). In between the metals and nonmetals, along the heavy diagonal line running from B to At in Figure 1.24 "The Periodic Table Showing the Elements in Order of Increasing ", is a group of elements with intermediate electronegativities ( ~ 2.0). These are the semimetals, elements that have some of the chemical properties of both nonmetals and metals. The distinction between metals and nonmetals is. Q: What are metals and good electrical conductors that tend to lose their valence electrons in chemical reactions called? Choices: - stable metals - conservants - precious metals - reductants A:
reductants

Q: Answer the following question given this paragraph: Summary Subatomic particles of the nucleus (protons and neutrons) are called nucleons. Anuclide is an atom with a particular number of protons and neutrons. An unstable nucleus that decays spontaneously is radioactive, and its emissions are collectively called radioactivity. Isotopes that emit radiation are Saylor URL: http://www. saylor. org/books. Q: What are the subatomic particles of the nucleus called? Choices: - cores - eukaryotes - protons - nucleons A:
A: nucleons
Question: Answer the following question given this paragraph: The suprahyoid muscles raise the hyoid bone, the floor of the mouth, and the larynx during deglutition. These include the digastric muscle, which has anterior and posterior bellies that work to elevate the hyoid bone and larynx when one swallows; it also depresses the mandible. The stylohyoid muscle moves the hyoid bone posteriorly, elevating the larynx,. Q: Which muscles raise the hyoid bone, the floor of the mouth, and the larynx during deglutition? Choices: - spicule - spirogyra - Hybrid - suprahyoid A:
Answer: suprahyoid

Answer the following question given this paragraph: Glycerol is a triol, an alcohol which contains three hydroxyl functional groups. A fatty acid is a long carbon chain, generally from 12 to 24 carbons in length, with an attached carboxyl group. Each of the three fatty acid molecules undergoes an esterification with one of the hydroxyl groups of the glycerol molecule. The result is a large triester molecule referred to as a triglyceride. Q: Glycerol is a triol, an alcohol which contains three what? Choices: - cytoplasm functional groups - hydroxl acidic groups - stark functional groups - hydroxl functional groups A:
**Answer**
hydroxl functional groups
