Answer:
The answer is A, It shows an exothermic overall reaction.
Explanation:
<span>Electromagnetic radiation will be emitted when any
object has a temperature above zero. The
reason behind this is that atoms within any object at a temperature above
absolute zero have energy, and thus is moving.</span>
<span>Atoms are at least partly composed of charged
particles, changed particles must be moving too.</span>
I think that the answer is A because if you think about water for an example. When water turns into ice, it's still technically water, just the molecules are frozen. The water is physically changed. It could also see why you think it is B but I don't think so completely. It doesn't really make sense to me. So I'd choose A. It's definitely not C or D.
The rate determining step for
the reactivity for the solvolysis of 2-chloro-norbornane depends only on the decomposition of a single molecular species which is
the 2-chloro-norbornane itself. For unimolecular reactions, the mechanism pathway being followed
is that of an SN1 mechanism.
Answer:
<span>SN1 mechanism</span>
