    Can Organic Chem Improve Existing Products for Health and Environment Solutions?

    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...

    What is the dissociation constant for hydroflouric acid?

    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.

    What is the dissociation constant for hydroflouric acid?

    oh boy, I have hated this equilibrium unit. I don't follow exactly. can you define some of the things? and is molarity (moles)? that be 0.1.

    What is the dissociation constant for hydroflouric acid?

    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

    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...

    How Do You Calculate Activation Energy and Heat of Reaction?

    For the reaction CO + NO2 ----> CO2 + NO the activation energy for the forward reaction is 135kj/mol of CO reacted. a) determine the heat of reaction b) from the data given, and the deltaHr for the reaction, determine the activation energy for the reverse reaction c) draw and label a...

    Convert Litres to Moles: Step-by-Step Guide

    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?
