  • Calculate the work done (in Joules) when 33.3g of tin dissol

    Sn(s) + 2H(aq) yields Sn2+(aq) + h2(g) I realize the equations PV=nRT and w=-p (change V) but have converted and can't seem to get it right? The work done is a type of boundary work due to the presence of hydrogen gas.

  • Sequence Proof

    So we have -a<Sn-SSn-S>-a, then Sn>S-a. But a=S/2. So Sn>S-S/2=S/2=a. Therefore, let a=S/2 and N is what we found, then we have Sn>a for all n>N. A sequence proof is provided. The proof is concise.
