Is Aspirin polar or non-polar?

In my thin layer chromotography lab the aspirin traveled far up the silica gel plate which would mean it's non-polar.

But looking that the chemical structure it looks to me like it is polar.

Why would it travel up the plate so far if it is a polar molecule or is it not polar for some other reason?

Why do non-polar solvents in thin layer chromatography cause lower Rf values? In this case, hexane was used as a solvent and benzhydrol and benzophenone were added to the TCL plate. The solvent (hexane) traveled far because I'm assuming due to capillary action, but the solutes did not travel far at all. Why?

For my lab on depositing thin films on a surface via thermal evaporation I was asked hat would have happened if we had obtained different color metals on the samples after the thermal evaporation? The only thing I can think of is there was a leak in the vacuum chamber so a nonintended product could have formed via chemical reaction or chemical mixing. Can someone please give me a clearer answer. Thanks!

C. Anti-reflection coatings So far you have explored constructive interference from multi-layer thin films. It is also possible for interference to be destructive, a phenomenon exploited in making antireflection coatings for optical elements such as eyeglasses. In order to allow the lenses to be thinner (and thus lighter weight), eyeglass lenses can be made of a plastic that has a high index of refraction (n p = 1.70). The high index causes the plastic to reflect light more effectively than...

There is something wrong with my arduino lab. I want my four leds to light up one after the other. Then the speaker plays music, and 4 leds change with music. But my code only makes one of them work. Please help me modify my code const int switchPin = 8; unsigned long previousTime = 0; int switchState = 0; int prevSwitchState = 0; int led = 2; // 600000 = 10 minutes in milliseconds long interval = 1000; int...
