It bonds to skin because
solid polymer requires the presence of water to get things started, be it in the air or on your skin. Without a little moisture, SuperGlue can't bond anything. This explains why the glue is so good at sticking fingers together.
The best way to predict the isomer of the given molecular information is to count the number of possible peaks present in spectra and compare it with the possible number of peaks given by each isomer. (Remember: This is not the final way to elucidate structure, but it is applicable in this question).
Explanation:
The number of peaks present in spectra are 8. Now, we will calculate the number of peaks given by each isomer.
ISOMER A: 1 peak for two equivalent methyl C attached to N
1 peak for carbonyl C
1 peak for methylene C
1 peak for methyl C
and 4 peaks for benzene C's as 2 carbons at ortho position and meta position to any of the two functional groups are equivalent hence give single signal.
So, 1+1+1+1+4 = 8
And it (Isomer A red) is the correct answer, because other two isomers give more than 8 peaks as they have no equivalent carbons in benzene ring.
Answer:
6moles of water
Explanation:
Given parameters:
Number of moles of oxygen = 3moles
Reaction equation:
2H₂ + O₂ → 2H₂O
Unknown:
Number of moles of water formed = ?
Solution:
To solve this problem;
compare the number of moles in the reaction.
1 mole of oxygen gas will produce 2 mole of water
3 moles of oxygen gas will produce 3 x 2 = 6moles of water.
