    chem

    Because 83kJ of heat is released when 1 mol of Calcium Chloride is dissolved. The question states 0.01 mol is used so 0.01mol x 83kJ/mol = amount of heat released by 0.01 mol

    Can this be used as a proof?

    I've seen an answer using the converse. Forgot which book it was from. Drongoski's method is fail-safe and I would've done that for sure

    Binomial Probability Q - Annoying the Heck out of me!

    9/10 shots make it. 1/5 shots are bullseyes, therefore 2/10 are expected to be bullseyes. Of the shots that make it in 10 shots, 2/9 are expected to be bullseye and 7/9 are not. Without me writing up a whole heap, your x and y or your p and q (whatever you use to represent chances of success...
