In the molecule HOCN (skeleton as written). Draw a Lewis structure that puts zero formal charge on all atoms. What orbitals overlap to make the C N sigma bond? O Csp? and Nsp² O Csp and Nsp O Csp°d and Nsp O Csp and Nsp3 O Csp? and Nsp O Cp and Np O Csp and Nsp O Csp and Nsp?

Write the Lewis structures for CH2N2, including all resonance forms, and show formal charges.

The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. Use the References to access important values if needed for this question. We can draw three inequivalent Lewis structures for dinitrogen monoxide, N₂O . The concepts of formal charge and electronegativity can help us choose the structure that is the most significant representation. 1. Assign formal charges to the elements in each of the structures below. Formal Charge N₁ N₂ :N,=N,-O: || A N=N,=Ô N-N,=O: C 2. The structure that contributes most significantly to the overall electronic structure of N₂O is ↑ Formal Charge

What are the formal charges present in in the ion CH3NH3*? Assume all atoms other an hydrogen hau an octet and that there are two central atoms. O N is 0 and C is +1 O N is +1 and C is -1 O N is +1 and C is 0 O N is 0 and C is 0 O N is +2 and C is -1

Consider the SO 3 molecule. How many valence electrons does the molecule have?   How many lone pairs of electrons are on the central atom?   How many lone pairs of electrons in total are on the substituent atoms?   How many resonance structures can be drawn for the molecule?  If the ion doesn't exhibit resonance, indicate "1" as only one structure can be drawn for the molecule.

2. Use the data provided below to calculate the lattice energy of calcium chloride. Electron affinity of Cl = -348.7 kJ/mol 1st ionization energy of Ca = 590.0 kJ/mol 2nd ionization energy of Ca = 1145.0 kJ/mol Bond energy of Cl2 = 242.6 kJ/mol Sublimation energy of Ca = 178.0 kJ/mol AH¡ [CaCl. (s)] =-795.0 kJ/mol

An incompicie Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of -1. N-C-C-H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges. H N=c=c-H

C : Based on the Lewis structure above, the central atom of this molecule has bonding electrons, _ pairs of non-bonding electrons, and (obeys, does not obey) the octet rule. pairs of -- O 0, 4, obeys O 8, 0, does not obey O 4, 0, obeys O 8, 0, obeys IICII

A certain element X forms two compounds with hydrogen, XH3 and X2H4 (H2X–XH2). The total bond enthalpies of XH3(g) and X2H4(g) are 846 kJ/mol and 1341 kJ/mol, respectively. What is the average bond enthalpy of the X–X bond?

Choose the best Lewis structure from those presented below. (It will help to work out the missing formal charges for the atoms in these different structures) [Image description: Lewis structure A has a N atom singly bound to two O atoms. There is one electron pair on N. One O atom has three electron pairs and the other O atom has two electron pairs and another single bond to a H atom. Lewis structure B has a O atom, 01, singly bound to a N atom and doubly bound to another O atom, O2. There is one electron pair on O1 and two electron pairs on O2. On the N atom there are two electron pairs and another single bond to a H atom. Lewis structure C has a O atom, 01, singly bound to another O atom, O2, and doubly bound to a N atom. There are is one electron pair on 01 and two electron pairs plus another singly bond to a H atom on 02. There are two electron pair on N. Lewis structure D has a N atom singly bound to a O atom, O1, and doubly bound to another O atom, O2. There are two electron…
