i hate her voice. it all helped though
she is hot and smart i love this video
You saved my life in AP Bio <3
I don’t get it in the polar bond at roughly 5.40, the polar bond of O+H….
the 2 electrons of the H are shared, but what about those of the O? And in
the non polar bond of H+H, each H has 2 electrons ( totalling 4) but why
are only 2 envolved in the bond?
your videos have been helping me study and clarify topics I was confused on
for my college Bio 101 course. thank you so much for posting!
