In gas chromatography, the number of peaks represents the number of compounds in an unknown sample, as retention times for each component differ. But what would happen if two components have the same exact retention time? Would you see two separate peaks or one?

I have done an experiment that found the initial reaction rate for a reaction that created gas in $\pu{kPa s^-1}$ by finding the slope of the tangent line at time = 0. How do I propagate uncertainty for this? Is there any uncertainty propagation that has to be done? $$\text{slope} = \frac{\pu{(99...

The question I have is with respect to this diagram. Which depicts a stream of protons and electrons entering a proton field with equal energy. Why is it that in the case where the energy of protons and electrons are equal, their angle of deflection is exactly the same? However when speed is kep...
