    From what I recall it was the full equation because I remember trying to balance it in the last five minutes and then lamenting over how I'd gotten it wrong after the exam was over. It might have been the ionic half equation, maybe I read the question wrong.

    Hoping it to be slightly lower. I think I got low to mid 60's. Any predictions to a grade. Hated the paper
