A 25.0 mL aliquot of 0.0550 M EDTA was added to a 57.0 mL solution containing an unknown concentration of V3+ . All of the V3+ present in the solution formed a complex with EDTA , leaving an excess of EDTA in solution. This solution was back-titrated with a 0.0490 M Ga3+ solution until all of the EDTA reacted, requiring 10.0 mL of the Ga3+ solution. What was the original concentration of the V3+ solution?

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

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.
