Answer:
B = CHCl2 + Cl2 --> CHCl3 + Cl
Explanation:
Free radical halogenation is a chlorination reaction on Alkane hydrocarbons. This involves the splitting of molecules into radicals/ unstable molecules in the presence of sunlight/ U.V light which ensures bonding of the molecules.
Free radical chlorination is divided into 3 steps which are:
The initiation step
The propagation step
The termination step
So in reference to the question, propagation step involves two steps.
The first step is where the molecule in this case the methylene chloride(CH2Cl2) loses a hydrogen atom and then bond with a chlorine atom radical to give a nethylwnw chloride radical and HCl.
The second step involves the reaction of this methylene chloride got in the first step with chlorine molecule to form trichloride methane and a chlorine radical.
You would find in the attachment the 2 step mechanism.
Answer:

Explanation:
The reaction we need to calculate:

1) 

We need the ClO in the products side, so we use the inverse of this reaction:


2) 

Now we need to combine this two:


The enthalpy of reaction:


Find number of moles and divide by volume to get molarity
Answer:
D. nucleus
Explanation:
In human cells, most DNA is found in a compartment within the cell called a nucleus.
Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the
total value could be found from B-Y. C is the value of your energy of
your products. X is your delta H value. So in this, your products are
higher energy than the reactants, so H is + and e2-E1 is positive so E2
>E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)
