Answer:
13 seconds
90 seconds
Explanation:
=Velocity of sidewalk = 1.2 m/s
=Velocity of woman = 1.6 m/s
Distance to travel = 36 m
Time = Distance / Speed
Time taken by the woman if she walks in the same direction the sidewalk is moving is 13 seconds
Time taken by the woman if she walks opposite to the direction the sidewalk is moving is 90 seconds
Answer:
Explanation:
Degree of unsaturation can be calculated by the formula
DU = (2C+2+N-X-H)/ 2 where
C is the number of carbons
N is the number of nitrogens
X is the number of halogens (F, Cl, Br, I)
H is the number of hydrogens. Oxygen and sulfur are not included in the formula because saturation is unaffected by these elements
So for C18H29NO2
DU = (36+2+1-29)/ 2 = 05.
The IR at 1735 cm-1 is indicative of a carbonyl type bond and when combined with the 13C NMR signal at 12 ppm and general H NMR is indicative of a (n) ester funtional group.
The HNMR peak at 6.3 ppm and broad signal at 3325 cm-1 in the IR is indicative of a (n) amine that is bonded to sp2 hybridized central atom.
