Answer:
exosphere and ionosphere.
Explanation:
very high up,the earth's atmosphere becomes very thin. the region where atoms and moleculesescape into space is referred to as the exosphere. exosphere is on top of the thermosphere.
scientists what is called the ionospherean extension of the thermosphere. so technically, ionosphere is not another atmospheric layer.
For the answer to the question above,
I am going to assume that MnO2 is a catalyst most likely breakdown of H2O2
H2O2----MnO2------> H2O + 1/2 O2
<span>in that case, B) is answered in the trump suit </span>
---
<span>edit: I need to have a plate account to see - which I don't </span>
is it something like
2H2O2 ---------------> 2H2O + O2
...............MnO2
<span>where MnO2 is underneath the arrow, in that case, it means it is a catalyst and production will DRASTICALLY decrease in production</span>
Alkenes undergo
Electrophillic Addition Reactions. Electrophiles are added across double bond. In given reaction the
H⁺ is first added across double bond as the double bond being denser in electron density act as a neucleophile. A
carbocation formed depends upon the nature of Alkene, if alkene is
symmetrical (as in our case) then positive charge can get any position, but in case of
unsymmetrical alkene the positive charge will go to that carbon which is attached to more carbon atoms. Then the water molecule attacks the carbocation and forms
alcohol.
As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.
Answer: D) Energy increases, wavelength decreases
A specific mass of a gas has a fixed volume at room temperature
