Re: Work in a Constant Volume

I don't exactly know how to relate this to neutralization of a reaction, but a neutralisation reaction is basically the reaction between an acid and a base to form a soluble salt and water. Neturalisation reactions are usually exothermic due to the formation of the bond between hydrogen and oxygen t...

Re: Work in a Constant Volume

There are 2 ways to think about this, either conceptually or mathematically - the formula for work is PdeltaV and no change in volume delta v =0 , and therefore w=0. Another way to think about it since there is no expansion, there is no work done by the system. and therefore work is 0

Re: Self Test 4A.3A

How are we supposed to know whether work done on a system is positive or negative

Re: W5/6 Sapling #6

You will need to multiply the Cvm by the number of moles to get the Cv, which you can then plug into your equation. It is important to note whether the value being given is the molar heat capacity or the heat capacity

Re: Concentration, Volume, and Pressure

Why is this statement false
(c) If one starts with a higher pressure of reactant, the equilibrium constant will be larger.

Re: Accessing the E-textbook [ENDORSED]

When we purchase Sapling, do we get an access code, online or do we have to get the physical access card shipped to us.
Is there anyway to get the code online, for International Students - since shipping it would be an expense almost the price of the code itself
