The effervescent sugar is a mixture of sugars in which a small amount of CO2 has been trapped. If some of this sugar is added to water the sugar solubilises and sets the gas free. On contrary, If the...

To make a chantilly, mix for example, 250 g chocolate and 250 g of tea. Melt the chocolate to form an homogeneous emulsion. To turn this emulsion into a Chantilly, you can , either use an ice bath,...

[students groaning] Happy Friday. I will schedule a review session, as I have done previously for the first exam. I will announce that next week sometime. I would guess it would likely be on Tuesday...

Kevin Kevin Ahern: Alright! Good deal. Let's see. A couple things. Somebody asked if I would send, or several people asked if I would send matching, problems for the 6th edition of the...

Kevin Ahern: I hope you had a good weekend? I hope. I had a nice weekend. I went to the coast and got away, which is why I didn't get the video posted until Sunday. I know there were several...

To make beads with a gelled shell and a liquid core prepare three solutions. For the first solution add to 400 g of calcium poor water with, for example, mint syrup 2 g sodium alginate thickening and...

Hi, this is Dr. B. Let's do the SO2 Lewis structure. On the periodic table: Sulfur, 6 valence electrons. Oxygen has 6. We have two Oxygens, though, for a total of 18 valence electrons....

This is the NO3- Lewis structure: the nitrate ion. Nitrogen has 5 valence electrons. Oxygen has 6, we have 3 Oxygens, and we need to add 1 for this valence electron up here. That gives us a total of 5...

OK, we're going to do the Lewis dot structure for O2. Let's start. Looking on the periodic table, we can find Oxygen in group 6 or 16, and that means it has 6 valence electrons. But we...

We touched on this in the video on resonance, but I want to devote an entire video to aromatic compounds. And one of the big mysteries in chemistry is why they were named aromatic compounds. Because...
