Answer:
Explanation:
Both calcium bromide and sodium bromide are ionic in nature so they will generate ions when dissolved in water .
CaBr₂ = Ca⁺² + 2Br⁻¹
NaBr = Na⁺ + Br⁻
Calcium bromide will generate greater number of ions per molecule according to chemical equation given above .
Benzoic acid ionizes but partially . Suger is a purely covalent compound so it does not generate ions at all .
In view of statement written above , the compounds can be arranged as follows according to conductivity from most to least conductive .
calcium bromide > sodium bromide > benzoic acid > sugar .

Image #1 is clearly sharing their electrons to complete an octet, which makes me believe it is a Double Bond.
Image #2 is a duplicate (if my computer is displaying this picture correctly) which if this is the case and my computer isn't the issue I'd say it is a Double Bond. I don't think "above" and "below" make a difference but it may depend on the attachments and where they were originally placed. Either way Image #1 and #2 are Double Bonds.
Image #3 if I recall accurately is where 4 valence electrons must be gained. I'm a bit fuzzy with valence electrons and recommended viewing Crash Course on this if you'd like to perfect your understanding on Valence Electrons, but I recall a similar question and I remember 4 valence electrons for this type of image. Wish I could help more on this. :(
Explanation:
Assuming that moles of nitrogen present are 0.227 and moles of hydrogen are 0.681. And, initially there are 0.908 moles of gas particles.
This means that, for 
moles of 
+ moles of 
= 0.908 mol
Since, 2 moles of = 
= 0.454 mol
As it is known that the ideal gas equation is PV = nRT
And, as the temperature and volume were kept constant, so we can write
= 
= 
= 
= 5.2 atm
Therefore, we can conclude that the expected pressure after the reaction was completed is 5.2 atm.
