BH3 CH4 NH3 H2O HF Part B)What are the ideal bond angles for each structure, and which are expected to be distorted? For the ones that are distorted look up on the internet and record their experimental values here:    Part C)According to Lewis and VSEPR theory, why do these changes occur?

1. For each pair of elements listed determine if they will form an ionic (I) or covalent (C) bond.    2.General Properties of Ionic and Covalent Compounds (Use THIS LINK to complete the table)  https://www.thoughtco.com/ionic-and-covalent-compounds-properties-3975966

How many single bonds are present in the correct Lewis Structure for C2H6?  All atoms in your Lewis Structure should follow the preferred bonding patterns discussed in lecture. Enter your response as a number.

The compound XeCl2F2 can exist in two different forms.  One form is polar and the other form is non-polar.  Draw a valid Lewis structure of XeCl2F2.  Then, draw two 3-dimensional representations of this molecule (including all lone pairs); one that shows the polar form with a correct dipole arrow and the other that shows the non-polar form of the molecule.

I got the Lewis structures right; however, I'm struggling with the questions below. Can you draw the structures and answer the questions?

Draw the Lewis structure of these compounds and use the electronegativity values, calculate the polarity of the molecules and write if the compounds will be polar, nonpolar, or ionic. Label the + and -next to the atoms of the molecule if they have charge. Also, write the overall dipole. HCN CH₂CHCl CH₃CH₃ CO₂

Do question 6 and 7 pleas if you cant do both of them just return the question please

Draw a Lewis structure for SiH4 BrF3 H2CO please show evidence that you are using all 5 steps in the process for drawing Lewis structure.

Draw the Lewis structure for H2S Before answering the following questions (You do NOT submit a picture just answer the questions. Given that sulfur obeys the octet rule WARNING:  Do NOT USE the internet or other sources  to find the structures. Use ONLY the rules taught in class. Answer the following questions for the  Lewis structure for H2S given that sulfur obeys the octet rule. Give answers as numbers (1,2,3 ...etc.) not words (one, two three etc.) How many double bonds exist in this structure  How many single bonds exist in this structure  How many bonds does the sulfur atom form  How many electrons surround the sulfur atom  How many lone pairs are around the sulfur atom  How many bonds does each hydrogen atom form  How many lone pairs are around each hydrogen atom  How many electrons surround each hydrogen atom

Thank you for the help in advance!

THIS is the equation N2H4 + O2 → N2 + H2O PLEASE HELP AND LOOK AT THE PICTURE FOR DATA  PLEASE HELP! I REALLY NEED HELP BECAUSE MY TEACHER HASENT TAUGHT ME HOW TO DO THIS PLEASE HELP!!!!!   Balance the equation (if not already balanced) Draw the models of the molecules in the equation, using Lewis structures, ball and stick models or something else that represents each of the atoms and how they are connected.  Identify bonds being formed or broken.  Use bond energy values from below to Calculate the overall energy of the reaction. Determine if the reaction is exothermic or endothermic. Draw a potential energy diagram showing the ∆H, reactants and products. Create one example of mass (g) to mass (g) stoichiometry problem.

Help me with the Lewis symbol for atom or ion.

* If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice.

i wanna help to complete this table (lewis structure, molecular shap and polar or non polar) table in attachments. thanks you so much

Deciding whether a Lewis structure satisfies the octet rule Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: Н — Н — - H No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is:| N= N No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. O No, it has the wrong number of valence electrons. The correct number is:| No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy…
