(b), propanal (C3H7OH) and propanoic acid (C2H5COOH) will form this ester, propyl propanoate.Which of the following pairs of substances reacts to produce the compound shown below?
C2H5CO2C3H7
(a) propene and ethanoic acid
(b) propanol and propanoic acid
(c) ethanol and butanoic acid
(d) ethene and propanoic acid
what are the experiments to show total internal reflection???
I'm not 100% sure about this experiment but,tag me whn u get the answr
and HOW did u figure that out?(b), propanal (C3H7OH) and propanoic acid (C2H5COOH) will form this ester, propyl propanoate.
C3H7OH + C2H5COOH ----> C2H5COOC3H7 + H2O.and HOW did u figure that out?
just add H at the end of C2H5CO2 and OH at the end of C3H7and HOW did u figure that out?
I'm not 100% sure about this experiment but,
Equipment: Ray box or Light source, Prism or Semi Circular Glass Block.
-The ray box is placed at an angle to the semi circular glass box, and rays are projected, the light ray is refracted through the glass block.
-The angle of incidence is gradually increased and it is seen that the light rays bend more and more (away from the normal).
-At one point, the angle of incidence refracts the light ray exactly at the surface of the glass block (90 deg.) and this is the critical angle of incidence.
-Beyond this angle of incidence, all the light rays that hit the surface of the glass block are REFLECTED back into the glass block.
-These light rays obey the laws of reflection (angle i = angle r) and thus giving proof for total internal reflection.
and HOW did u figure that out?
tag me when u get the answerWhen drawing a straight line of best fit in physics atp, do we draw a line that has equal number of points above and below it. And how far from one point can the line be? any tips for drawing that line please?

We're asked for an experiment for total internal reflection, I don't quite get how what you say will prove that total internal reflection occurs.I was thinking why not first calculate the theoretical critical angle, by calculating the refractive index first by sin i/ sin r. Then get the theoretical critical angle by n = i/sin c. in the end, compare this with the experimental value.
We will all do exactly the same paper at the same time of the day. That interestingand only 8 days are left till paper

You don't have to make bizarre lines or curves for fitting all the points in the graph.tag me too
oops i mixed up with the critical angle experiment SorryWe're asked for an experiment for total internal reflection, I don't quite get how what you say will prove that total internal reflection occurs.
Hehe. No problem.oops i mixed up with the critical angle experiment Sorry
not 8 but 6and only 8 days are left till paper
