  • Dumbell weights problem?

    Okay so I have this little problem with my dumbells.

    My uncle was using them and one side of the dumbell is locked on SUPER tight. I can't spin the thingy around to remove it, it won't even budge. :S and he's not here anymore.

    Any ideas on how to remove the weight on this one side of the dumbell?

  • Maths show that question calculus?

    Formula:

    dT/dt = -k (T-Ts) + P

    The temperature inside the engine of John's car is 65°C at 6pm, when he turns the engine off, and the outside temp, Ts = 20°C, from 6pm to 6am the next morning. At 9pm the temp inside the engine dropped to 33°C. Assume Ts is constant from 6pm to 6am the following morning.

    Show that temperature is T = 20 + 45e^-0.4t

  • Galvanic cells help, chemistry?

    I need some help with these questions :\

    Write half equations for the reaction occuring in each half-cell and hence write an overall equation for the reaction in each cell.

    a) Fe3+/Fe2+ and Zn2+/Zn

    anode reaction, cathode reaction, overall reaction

    -Consider the Pb2+/Pb half-cell. If lead is a stronger reductant than copper, but Pb2+(aq) is a stronger oxidant than Zn2+ (aq), where in your electrochemical series would you place the following equation?

    Pb2+ (aq) + 2e- -> Pb(s)

  • Protein questions? (chemistry)?

    1) Some proteins, such as those that make up hair and wool, adopt helical structures. Explain how this helical arrangement is maintained.

    2) How can the identification of proteins present in a person be used to identify and potentially treat disease?

    Also, is the general name of the molecules that form the basic unit of proteins Amino Acids? if so, what is the general structure for them and the functional groups in them? *checking a question to see if I'm right lol

  • Japanese noob tourist questions?

    Okay so I just finished year 11 and next year I'm going to be in year 12 where I get my ATAR score.

    Once I hit the big ATAR score I'll probably go overseas to Japan by myself for a break. And I got a few questions:

    1) Is Tokyo/Japan easy to navigate? How would I get around to places I wanna go? like say a shopping mall, a tourist place, etc.

    2) Is the language barrier a big problem? I don't speak Japanese.

    3) Is it easy to get lost there?

  • Chemistry questions help!?

    Potassium iodide and lead (II) nitrate solutions react together to form a precipitate of lead lead (II) iodide according to the equation:

    2KI (aq) + Pb(NO3)2 (aq) -> PbI2 (s) + 2KNO3 (aq)

    a) in each of the following cases determine which of the two reactants is in excess and by what amount (in mol):

    i) 1.0 mol of potassium iodide and 1.0 mol of lead (ii) nitrate

    ii) 0.50mol of potassium iodide and 2.0 mol of lead (ii) nitrate

    In each of the following cases, calculate the mass of the precipitate formed.

    iii) 1.0g of lead (ii) nitrate and 1.0g of potassium iodide

    iv) 0.60g of lead(ii) nitrate and 2.6g of potassium iodide

  • Chemistry help! (molar concentration)?

    question 1:

    -A standard solution of Sodium Carbonate was prepared by dissolving 1.80g in 250mL of deionised water.

    Calculate the molar concentration (M) of the standard solution (use Na = 23.0, C = 12.0, O = 16.0). Show all working and formulae used.

    question 2:

    -20mL aliquots of the standard solution were taken and titrated against HCl solution using methyl orange indicator. The mean titre was 27.17mL of hydrochloric acid.

    use the information to calculate the molar concentration (mol L^-1, M) of the hydrochloric acid.
