Organic chemistry is difficult; those who study it have alkynes of trouble. Alkaline batteries are the focus of a video on electrochemistry, explaining how batteries work and why they are called alkaline batteries. The resource also...

Review of reduction and oxidation opens this video. It really helps stimulate understanding of these biochemistry topics. By explaining the loss or gain of electrons, Salman Khan is able to clarify the concept of respiration processes.

Oxidation states in elements are the focus of this chemistry video. Sal illustrates how when an element loses electrons, it is moving toward a state of oxidation, and when an element gains electrons, it is moving toward a state of...

In the previous video, Sal presented how elements move toward a state of oxidation (by losing electrons), and a state of reduction (by gaining electrons). This lecture takes that concept a bit further, and he provides more examples.

Look at dilations exponentially. Using a fractal from a museum exhibit, the installment from the Math at the Core: Ratios series introduces the term dilation. The presenter points out that dilations can make images either smaller or...
