Aluminum oxide (Al2O3) and iron (Fe) react according to the following balanced equation:
4Al2O3 + 9Fe - 3Fe304 + 8A|
If there are 10.2 grams of Al2O3 and 11.2 grams of Fe, which statement
identifies the limiting reagent in this reaction and best supports that claim?
A. Fe is the limiting reagent, because the reaction requires nearly
twice the mass of Fe as of Al2O3.
B. Al2O3 is the limiting reagent, because there are only 0.1 moles of
Al2O3 and twice as many moles of F
C. Fe is the limiting reagent, because 9 moles of Fe are required for
every 4 moles of Al2O3.
D. Al2O3 is the limiting reagent, because there are fewer grams of it
present.

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
