Organic chemistry is difficult. Those who study it have alkynes of trouble.

step 1 was the slow step because k1 was less than k2 which means it takes longer for step one to occur. you can also think of it in terms of activation energy. If k1 is smaller than k2, then the activation energy of k1 is higher (which means it takes longer- higher hill on the reaction profile diagr...

Can someone help me with #6
I don't understand how both of them are nucleophiles?

I think they represent which carbon is the group attached to. For instance, In 3-ethyl-2-methylhexane. Hexan shows a 6 carbon chain and since there are two
different alkyl groups attached, we put an ethyl group on the number 3 carbon atom and a methyl group on the number 2 carbon atom.

Can someone please help me with #3? I used the integrated rate law for first order and I got t=205 seconds

The first thing to know is that a double vertical line (||) is used to separate the anode half reaction from the cathode half reaction (represents salt bridge). A single vertical line (|) is used to separate solid, liquid, gas, or aq on the same side. A comma is used to separate same states of matte...

Use the Nernst equation in order to calculate the PH of the electrolyte at the hydrogen electrode.
You can start with E=E(node)-(0.0256V/n) ln([Sn^2]/[H^+]^2) and Just solve for the concentration of [H^+]^2.
Then convert that concentration to PH by -log([H^+]

Hope this helps!

Can someone please explain conceptually how cell potential and reaction Gibbs free energy are related?
Thanks!

You can do this problem in 3 reversible steps. First, you have to heat the reactants to 100 celsius, then find the entropy of phase change, which is given in the problem ( 109.0J/Kmol), and then cool the products at 85 celsius. After that you just add the three different entropy together. The first ...

The problem 8.65 tells us to calculate the standard enthalpy of formation of dinitrogen pentoxide, so we know that's our product. We have to write out the net equation. Dinitrogen pentoxide ( 2 nitrogen and 5 oxygen) is formed when diatomic molecules N2 and O2 come together. So we know nitrogen gas ...

I know that both Intensive properties and extensive properties are types of physical properties. The main difference is that extensive properties depends on the matter present, for example, heat capacity is an extensive property because the heat required depends on the amount of substance present. T...
