thermochemistry
so i was studying thermochemistry and they use ΔH = -x kJ/mol, my doubt is what does that per mol refer to? per mol of what? [my teacher said that it refers to per mol extent of reaction but tbh i still do not get it]
solution question doubt
In the question no 5, we know that Kh proportional to Temp & 1/Molecular Mass. But, there is two factors the answer is given C,how?
Lyophilic or lyophobic?
Confused in how can i actually figure out between them
like for exam i was given this as a quiz :
identify the lyophilic compounds
1. Blood
2. Fog...
kinematics/aod
if i solve by drawing v-t graph and check the nature of the slope then acceleration comes out to be decreasing (for magnitude of accel we make rightward parabola in v-t graph) but solving by normal differentiation gives acceleration as constant. Can someone pls explain why im getting different answers and which one is correct?
magnetism
Why is this wrong, if i take emperial loop outside the wire, there is magnetic field there but the law says it's zero
Circular Motion
Can anyone please solve this problem, i have tried it but unable to do so
Found angular acceleration but that didn't work out...
equivalent resistance
help. i tried using potential method and kcl, cant get answer. (answer is (4) 'r')
conversion in amines
just wanna know what happens and the logic between them . and if theres any short trick to do this conversion. thanks
