What is an example of a binary acid and its use? Hydrochloric acid (HCl) is a binary acid used in metal refining and pH adjustment in water treatment. 15 Why are binary acids named with a "hydro-" prefix? The "hydro-" prefix in binary acids highlights their composition of hydrogen and...
What is the total number of nonmetal atoms present in the formula of {eq}Mg_3(PO_4)_2 {/eq}? (a) 10 (b) 7 (c) 9 (d) 13 Ionic Compounds: An example of an ionic compound composed of a cation and anion is sodium chloride. We can classif...
What is an example of an oxidizing agent? What is the oxidation state of the unknown atom A in the oxide AO42-? a) +2 b) +4 c) +6 d) +0 e) +8 What information is given in redox half reactions? How to find the oxidation number of nitrogen in N_2O? Give general steps to...
Is arsenic a metal, a nonmetal, or a metalloid? What other elements are in the same group on the periodic table as arsenic? What are some characteristics of metalloid? Which of the elements in the following periodic table are noble gases?
Sodium chloride is an ionic compound, but what is an ionic compound? Ionic compounds are a type of chemical compound where the oppositely-charged ions of a metal and a nonmetal are attracted to each other to form an ionic bond. The compound formed from the bonded ions will have very ...
Industrial Uses of Silicon Let's zoom in a ways, from the global silicon cycle to how humans interact with silicon. Pop quiz: what are the properties of a metal versus a nonmetal? Metals are malleable, ductile, and electrically conductive, while nonmetals are hard, brittle, and often insula...
A metal that is a combination of two or more elements, at least one of which is a metal. Alloy Any combination or compound of metals fused together; a mixture of metals; for example, brass, which is an alloy of copper and zinc. But when mercury is one of the metals, the compound ...
electronegativity, and chemical reactivity differ from both the nonmetal and metal elements in the periodic table. For example, the chemical reactivity of boron is like that of a metal in some cases, and like that of a nonmetal in other cases, depending on what material it is reacting with....
How to Tell if a Bond Is Ionic or Covalent? An ionic bond forms between a nonmetal and a metal in which the nonmetal attracts the electron from the other atom. Ionic bonds are high in polarity, have no definite shape and have high melting and boiling points. At room temperature, an ion...
word alloy described as a "mixture of metals", but that's a little bit misleading because some alloys contain only one metal and it's mixed in with other substances that are nonmetals (cast iron, for example, is an alloy made of just one metal, iron, mixed with one nonmetal, carbon)...
