Topics 4.1 - 4.4

Your willingness to share your material makes me a better teacher and my students benefit from that! Thank you!!!

This video helped me a lot. I just don't understand how a ionic compound like NaCl can conduct electricity when molten. What I am guessing is that since it is molten, heat has been applied to NaCl (s). The heat provides kinetic energy to NaCl(s). This kinetic energy overcomes the ionic bond between Na+ and Cl- which makes them disassociate, freeing them from the crystal lattice. Since they are free flowing, they can conduct electricity. Though that is just my hypothesis with a background of a couple months of taking AP Chem. Could you clarify this for me?

Thank you for these videos, are these AP chemistry questions from collgeboard, also where can i practice more of topic-wise questions.

while solving questions for 4.1-4.4 on college board I noticed that there are a lot of balancing questions that take some time, got any tips on that, are they even still in the current CED?
