How do I find the number of valence electrons and make it a lewis structure?

where is c? in the lewis structure?

Consider the molecules of furan and benzene. The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: Furan H X Benzene

Please answer both questions as they are calculated together but just a heads up they are different questions. Thank you for helping me

Consider the following ion: BrO3−. a)  Show the full electron configuration for Br.  b)  Draw the most correct Lewis structure for BrO3− and briefly explain why your Lewis structure is correct.  c)  If the structure is stabilised by resonance, draw at least one of the possible resonance forms. If it is not stabilised by resonance, briefly explain why.  d)  What is the electronic geometry of BrO3−? What is its molecular shape?  e)  Does BrO3− have a dipole moment? Briefly justify your answer.  f)  On average, would you expect IO3− to have longer or shorter bonds than BrO3−? Briefly explain your answer.  g)  Which of the following molecules would you expect to have the lowest vapour pressure? Briefly explain your choice.  h)  What is the molecular formula for Compound C? What is the empirical formula for Compound C?  please answer c, d and e

A compound composed of only carbon and chlorine is 85.5% chlorine by mass. Propose a Lewis structure for the compound.

How does the written Lewis structure for potassium chloride differ from that of hydrogen chloride?

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure a=ö] [[:N_N=N]] Yes. Is the proposed Lewis structure reasonable? 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: Yes. 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:* ☐ Yes. 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 the octet rule, enter "0,0".

Draw the Lewis symbols for the atoms Al and O. Use the Lewis model to determine the formula for the compound that forms from these two atoms.

carbon tetrachloride was formerly used in fire extinguishers for electrical fires.it is no longer used for this purpose because of the formation of the toxic gas phosgene,CL2CO.wRITE THE LEWIS STRUCTURES for the methane and ethane molecules.
