Comment:

First,  I think the topic is one students often struggle with.  Reactions, whether it's identifying the type of reaction or predicting products is one of the most difficult topics for students.

I like the various examples for students practice, and I think the quiz is an excellent way for students to check their understanding.  Have you thought about expanding this to include all the reaction types that you teach?  This would be a great way to introduce the topic and then another way for students to review with later.

All your fonts and colors are easy to read and very clear.  I didn't hear any sound.  Was this intentional?  I think some sounds, not too many, would help keep students engaged and interested in the tutorial.

I think having the objectives present is great.  This really helps students recognize what they will be learning and expected to know and do once they are finished.

Your visuals are colorful and are excellent ways for students to connect concepts to meaning.  I like how you used the dots to represent reactants and products.  Using colors that when combined create a new color is genius.  Students know when you mix blue and yellow, green is produced.  So that is an alternate way of helping them connect their prior knowledge to new concepts when building understanding.

Technical Remarks:

One remark, not sure if it would be technical or just a regular comment, but I think there maybe too many transiitions on the slides or the transitions may need to be sped up a bit.  I felt I was waiting a while for the information to come on the screen.  This many transitions may be a bit distracting.  But again that might be a personal preference.
