  • TD Visa Debit Card help?

    I tried to but something on the web, (which is under my limit) but my card has been rejected twice.

    They say that they need "credit card authorization" , I put in everything correct, and my card is activated and there is no security hold from the bank. However the 3 digits on the back of my card, is something that I didn't put in. But they didn't mention it. BTW I was trying to buy plane tickets.

    A current television commercial for Advil Liquid Gel (liquid medicine) tablets promised faster relief than regular solid Tylenol tablets. Assuming that it is a chemical reaction between the medicine (in the products) and chemicals our body that leads to the pain relief, use your studies in this unit to propose why Advil's promise is a reasonable one.

    BTW I am studying rates of reactions in school. I just don't know the answer, normally I would say that there would be more collisions, a catalyst, but I would really really really appreciate it if anybody helps me out.

    Thanks to all helpers. Have a great Christmas!

  • Why is this mechanism not reasonable?

    A + BC , turns into: D + E

    D + F turns into G + A

    E turns into: BC + F

    And by "turns into" I put this in there instead of the typical arrow you would see which points to the right which displays the products.

    Thanks to all helpers

  • Rates of reaction questions please help?

    The destruction of ozne in the stratosphere by freons (chlorine containing hydrocarbons) is believed to take place according to the mechanism below.

    Step one Cl + 03 - CLO + 02 fast

    step two 03 - 0 + 02 slow

    Step 3 CLO + O - CL + O2 fast

    What is an intermediate?

    How many catalysts are in this mechanism?

    What is the product?

    By the way when I write for 03 - 0 + 02

    The 02 is meant to be oxygen. The 03 is the same with an extra bond. And bythe dash (-) I mean its the same as an arrow which faces right to show the products.

    Anyway I'm a rookie when it comes to chemistry so if you could explain why for each question I would be really thankful. Thanks to all helpers.

  • How do I find heat change , after I have have Q , C ,delta T and the mass.?

    So in a really long question i have found out q by using q=C(delta)T

    C is 10.8

    T is 6.42 and the answer was 69.33 KJ

    The problem is I don't really understand the question basically I may as well right it out

    216 g of NH(little 4)NO(Little 3)(s) is dissolved in water in a styrofoam coffee cup. If the initial temperature is 18.75 degrees pf the calirometer and its final temperature is 12.33 degrees what is the heat change for this reaction per mole of NH(little 4)NO(little 3)(s) dissolving? The calorometer and contents has a collective heat capacity of 10.8 KJ/ degrees?

    When I write for example NH(little4)NO(little 3)(s) , I mean that there is a little at the bottom right of the letter to it's left.

    And I really thank you kind individuals who help. Thanks!
