What is the electron configuration of #"Co"^"3+"#? - Socratic
2016年1月3日 · The electron configuration of "Co"^(3+) is ["Ar"] 4s 3d^5. "Co" is in Period 4 of the Periodic Table, and "Ar" is the preceding noble gas. Cobalt is also in Group 9, so it must have 9 valence electrons. The valence shell configuration is therefore 4s^2 3d^7, and the core notation is bb"Co": ["Ar"] 4s^2 3d^7 When a transition metal forms an ion, the s electrons are removed …
How many resonance structures are there for #CO_3^(2
2015年10月30日 · The answer is 3 May i recommend a video () Let’s consider the Lewis structure of the carbonate ion, CO32‐ . The correct Lewis structure for this ion has one carbon‐oxygen double bond, and two carbon‐oxygen single bonds. Each of the singly bonded oxygen atoms bears a formal charge of ‐1 and all other atoms are neutral. But which of the three oxygens …
What is the oxidation number of carbon in the ion (Co3)2
2015年10月22日 · The carbon is fully oxidized. Therefore, it is C, IV^+. The sum of the formal oxidation numbers in an a complex or compound ion must sum to the charge of the ion. Here the charge is -2. Oxygen typically has an oxidation number of -II, and it does here. So 3 xx -2 + C_(ON) = -2. And what therefore is C_(ON)? What is the oxidation number of carbon in …
What is the name of the compound Cr_2(CO_3)_3? - Socratic
2016年4月24日 · Chromium(III) carbonate In order to name an ionic compound, you must identify the cation, which is the positively charged ion, and the anion, which is the negatively charged ion. Cations are always written first in the chemical formula of an ionic compound, followed by the anions. "Cr"_ color(red)(2) ("CO"_ 3)_color(blue)(3) It's important to remember that ionic …
How many electrons are there in carbonate ion, #CO_3^(2-)
2017年10月4日 · The carbonate dianion is CO_3^(2-) Now, clearly, the ion must contain 2 more electrons, than it does nucular charges.....in one formula unit of CO_3^(2-) there are 6_C+3xx8_O=30*"positively charged nuclear particles". And thus there MUST be 32 electrons conceived to whizz about the nuclei. And their presence is clear from the Lewis structure of …
What is the charge on a carbonate ion - Socratic
2015年12月19日 · The carbonate dianion MUST have 2 more electrons than it does nuclear protons. Let's see if it does. The number of nuclear protons are the number of positively charged particles contained in atomic nuclei. Z, the atomic number, =6 for carbon, and 8 for oxygen. In the carbonate atom nuclei there are therefore 30 positively charged protons. So how many …
How many total atoms are in the formula Al_2(CO_3)_3? - Socratic
2017年3月26日 · Well, if I have done my sums right, there are 14 atoms in the one formula unit of "aluminum carbonate". And so there are 2xxAl+3xxC+9xxO="14 atoms".
What is the equation for this reaction: Carbonate + Sulfuric Acid?
2018年7月30日 · H_2SO_4 + X CO_3 == H_2O + CO_2 + X SO_4 The positive ion on the Carbonate is unstated, so it is represented by X. The Hydrogen ion on the Sulfuric Acid combines with Carbonate to break the Carbonate down into water and Carbon Dioxide.
What are the resonance structures for CO_3^-2? - Socratic
2017年1月27日 · This is a carbonate ion. A resonance structure means that there are more than one way to draw the ion. First, determine the total number of electrons available: 1 Carbon - 4 3 Oxygen - 6(3) = 18 And the charge of -2 gives you an additional 2 electrons. Hence, there are 24 electrons in total (4+18+2=24) Carbon would be in the middle which gives you However, note …
What is the ionic equation for Na2CO3 + Ba(NO3)2 - Socratic
2016年10月19日 · The net ionic equation is Ba^(+2)(aq) + CO_3^(-2)(aq) -> BaCO_3(s) Both reaction compounds are ionic and are aqueous in solution. The products are a relatively insoluble compound and a compound that remains in solution as ions. The complete ionic equation is 2 Na^(+1)(aq) + 1 CO_3(-2)(aq) + 1 Ba^(+2)(aq) + 2 NO_3^(-1)(aq) -> 2 Na^(+1)(aq) + 2 …
