Jun 30, 2016 · The electron configuration of "Zn"^(2+)" is "1s"^2"2s"^2"2p"^6"3s"^2"3p"^6"3d"^10". The atomic number of zinc is 30, which means that all zinc atoms have 30 protons in their nuclei. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons. The electron configuration of a neutral zinc atom is "1s"^2"2s"^2"2p"^6"3s"^2"3p"^6"3d"^10"4s"^2". The ...

Jul 27, 2016 · Isoelectronic means the same number of electrons, or the same electronic structure. The electron configuration of "Ni" is [Ar] 3d^8 4s^2. The electron configuration of "Zn" is [Ar] 3d^10 4s^0. It may seem tempting to remove electrons from the 3d orbitals, but the 4s orbitals are higher in energy for these first-row transition metals. Hence, it makes sense to remove electrons from them upon ...

Dec 20, 2016 · This information was given along with the question: A piece of zinc metal is placed in a 1.0 M solution of hydrochloric acid at 25 C°.

Jun 25, 2014 · The reduced component is H₂. We use oxidation numbers to identify oxidation and reduction products. For this question, two rules are important: The oxidation number of an element is zero. The oxidation number of an ion is the same as its charge. In the equation Zn + 2H⁺ → Zn²⁺ + H₂ the oxidation numbers are Zn = 0 (Rule 1) …

Mar 19, 2016 · The Zn^(2+) ion is a DIAMAGNET. Zn^(2+) is a d^10 species, and, therefore, diamagnetic. There are, I recall, one or 2 recent examples of Zn^+ complexes, which feature Zn-Zn bonds.

Aug 23, 2016 · Use the proton balance method given below to obtain: 2"CH"_3"COOH" + "Zn"("OH")_2 rarr "Zn"("CH"_3"COO")_2 + 2"H"_2"O". One way to do it is to think of it as a proton donation (acid) reaction and a proton acceptance (base) reaction: Acid: "CH"_3"COOH" rarr "CH"_3"COO"^{-} + "H"^+ Base: "Zn"("OH")_2 + 2 "H"^{+} rarr "Zn"^{2+} + 2 "H"_2"O" The acid gives one mole of protons but tge base takes ...

Jun 17, 2015 · You take a look at its electron configuration. Zinc is located in period 4, group 12 of the periodic table and has an atomic number equal to 30. This means that neutral zinc atom has a total of 30 electrons surrounding its nucleus. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. "Zn": 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 or, if ...

Jun 27, 2017 · "Zn"("OH")_ (2(s)) rightleftharpoons "Zn"_ ((aq))^(2+) + 2"OH"_ ((aq))^(-) Zinc hydroxide is considered insoluble in water, so right from the start, you know that you're dealing with a solubility equilibrium between the undissociated solid and the solvated ions. Now, each mole of zinc hydroxide contains one mole of zinc cations, 1 xx "Zn"^(2+) two moles of hydroxide anions, 2 xx "OH"^(-) This ...

The concentration of the #Zn^(2+)# ions in blood serum is 1.2 ppm. Express this amount in terms of millimole/L and milliequivalent/L. A solution is prepared by dissolving 3.5 #g# of #KCl# in water & making the volume of solution to 250 #mL#.

Apr 13, 2018 · How would you draw the galvanic cell for the reaction: Zn2+ + 4NH3 ---> [Zn(NH3)4]2+ Is this correct? The textbook is showing these two half reactions. I get a little confused when passive electrodes are involved in galvanic cells.
