this is gonna be absolutely awful tmrw I genuinely cannot fathom any concepts of physics. I know damn well the college board bouta cook up some bs on the FRQs. I don't even want tips I just wanted to vent 😭
On Question 2 or 3 don't remember on version J it asked if it was a redox reaction and I said no because the oxidation numbers between Cr didn't change as they were both +6 when I calculated it. I want to make sure that is correct because the equation with dichromate seemed like a redox reaction but the oxidation numbers say otherwise
