They are almost the same size and they are rocky planets (like not made of gas)
Hope this helps :)
Answer:
The Earth's atmosphere is 78% nitrogen gas or N2. Even though there is so much nitrogen in the air, there is very little in the Earth's crust. It can be found in some fairly rare minerals such as saltpeter. Nitrogen can also be found in all living organisms on Earth including plants and animals.

Answer:
t-butyl cation
Explanation:
Generally a dehydration reaction occurs when an organic compound loses water molecules to form alkenes. However, in an acid-catalyzed dehydration, the dehydration reaction occurs in the presence of an acidic compound which acts as a catalyst. Therefore, for this specific case, the hydride will migrate and a t-butyl cation will be formed. This is because it is more stable due to the presence of three electron releasing alkyl groups which can stabilize a positive charge compared with the secondary cation formed when the methyl group migrates.
Answer:
Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.
