Answer:
All of the above
Explanation:
I believe all three are true. They see how the organism is similar to other organisms. They see if the organism has the characteristics of an animal or plant. They look at what makes the organism unique.
So,
Formate has a resonating double bond.
In molecular orbital theory, the resonating electrons are actually delocalized and are shared between the two oxygens. So the carbon-oxygen bonds can be described as 1.5-bonds (option B). I'm not sure if option C is correct, however, because the likelihood of both delocalized electrons being in the area of one oxygen atom is less than 50%.<span />
Answer:
4.86 moles of HCl
Explanation:
1. First write the balanced chemical equations involved in the process:
2. Calculate what amount of 
is formed in the first reaction.
As the yield of each reaction is 90.0%, the amount of produced is the following:
3. Calculate the amount of HCl produced.
The total amount of HCl produced with a 90.0% yield is:
