• Nov 08, 2010 · Hi everyone, I'm trying to make sure I understand the difference between ionic and covalent bonds, and I'm getting a little hung up on Cr2S3. I think its Ionic because Cr is a metal and S is a non-metal, but when trying to verify online I'm getting multiple answers.
  • Draw a Lewis structure for the resonance form of AsO4^-3, with the lowest possible formal charges. Include any nonzero formal charges and lone pair electrons in the structure.-What is the Oxidation number of As-What is the Oxidation number of O. Best Answer 92% (12 ratings)
  • 2) IF5. 3)CO32-4)SiCl4. 5)SO42-For the molecules above, draw resonance structures if possible. What is resonance? What is ionic and metallic bonding? Give examples for each. VSEPR theory: What is the basis for this theory and how does this theory help to explain the molecular geometries of complicated molecules?
  • Dec 19, 2020 · On the atomic level, bond order is the number of bonded electron pairs between two atoms. In diatomic nitrogen (N≡N), for instance, the bond order is 3 because there are 3 chemical bonds linking the two nitrogen atoms.
  • Nov 24, 2018 · In the formal way we find how many electrons we have (step 1), how many each atom needs (step 2), how many of those are bonding (step 3 & 4), and how many are lone pairs (step 5). This info can then be used to determine the Lewis Dot Structure. Step 1: Find valence e- for all atoms. Add them together. N: 5 F: 7×3 = 21. Total=26
  • E) All noble gases have eight valence electrons. 29) Which of the following would have all of it’s valance electrons paired in it’s lewis structure representation? A) Al B) P C) S D) F E) Xe 30) How many single covalent bonds must a silicon atom form to have a complete octet in its valence shell? A) 3 B) 4 C) 1 D) 2

Apr 27, 2017 · Most resonance structures and coordination compounds are also supported. Simply follow the steps below: If you do not already know the name or chemical formula of the molecule you wish to generate a dot structure for, you can browse the list of molecules at molcalc.org by clicking here .
Resonance structures are all of the possible different Lewis structures that a molecule might have. Calculating the formal charge for a molecule allows you to determine which resonance structure is more likely to be the molecule's correct structure, and the Lewis structure which is considered the most correct will be the structure that has ...

There are four resonance structures for the N 2 O 4 molecule. Draw all the resonance structures in your own. The skeletal structure of the molecule is. What is the average N ? O bond order? (Use a decimal number for an answer, not a fraction.) Bond order = Expert Answer 100% (1 rating)
At the resonance : X L – X C = 0 or X L = X C. The Impedance will be: Where Zr is the resonance impedance of the circuit. Putting the value of X L – X C = 0 in equation (1) we will get: Zr = R. Current I = V/ Zr = V/R. Since at resonance the opposition to the flow of current is only resistance (R) of the circuit.
