    Organic Chem - Products

    Hey, I have a question which asks me to provide two examples of how organic chem can be used to improve existing products and therefore provide solutions to newly identified health or environment problems. One example is unleaded gasoline, instead of leaded. What are some others? I've...

    Dissociation constant

    thanks for your effort. I get it more, but I am still not comfortable with this. I'm going to need to give it a look more later, and keep looking back at it more and more.

    Dissociation constant

    oh boy, I have hated this equilibrium unit. I dont follow exactly. can you define some of the things? and is molarity (moles)? that be 0.1.

    Dissociation constant

    I understand this tells us how strongly binded a solution is. So I hve hydroflouric acid, it says it contains 2.0g of HF per litre and has a PH of 2.2. How do I figure what the dissociation constant for HF is? Thanks

    Formation of products is strongly favoured in the acid-base system

    yes it is. Sorry, didn't know how to put it in properly.

    Formation of products is strongly favoured in the acid-base system

    The formation of products is strongly favoured in the acid-base system: HX + B- <--- HB + X- ----> a) Identify the bases competing for protons. b) Which base is stronger? c) Which is the weaker acid, HX or HB? d) Does the K for this system have a large or small value...

    Litres to moles?

    the info I have is: a 1L container with 5mL of water helt at 20degcel I need to find the vapour pressure. I'm supposed to use PV=nrt right? how do I get n though?
