Answer: The correct option is B.
Explanation: There are 2 regions of the solar system.
1) Inner region: There are 4 planets which lie in this region: Mercury, Venus, Earth and Mars. The inner region planets are rocky in nature. The orbit time of these planets around the sun is short. They have 0, 1 or 2 satellites in total. There is no ring system in these planets.
2) Outer region: There are 4 planets which lie in this region: Jupiter, Saturn, Uranus and Neptune. The outer region planets are gaseous in nature. The orbit time of these planets around the sun is long. They have usually more number of satellites around them. Ring system in these planets is very common.
Hence, Mars resides in the inner region of the solar system because it has a rocky surface that one could firmly stand on.
Answer:
Carbon exists in several isotopes. ... Carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 contains 8 neutrons. Carbon-12 and 13 are stable isotopes, which means that the nucleus does not undergo radioactive decay. Carbon-14 possesses an unstable nucleus which undergoes radioactive decay.
Explanation: Trust me :)
Pressure<span> with Height: </span>pressure<span> decreases with increasing </span>altitude<span>. The </span>pressure<span>at any level in the atmosphere may be interpreted as the total weight of the </span>air<span>above a unit area at any </span>elevation<span>. At higher elevations, there are fewer </span>air<span>molecules above a given surface than a similar surface at lower levels</span>
It is formed via the more/most stable carbocation.
What justification exists for Markovnikov's Rule?
A carbocation is created as a result of the protonation of the alkene by the protic acid. The carbocation that has the most alkyl substituents on its carbon holds the positive charge, making it the most stable carbocation. As a result, the addition of the halide to the carbon that has fewer hydrogen substituents makes up the majority of the product.
Markovnikov's rule
According to the Markovnikov rule, a proton is added to the carbon atom with the greatest number of hydrogen atoms connected in addition to processes involving alkenes or alkynes.
Anti-Markovnikov Rule
According to the Anti-Markovnikov Rule, in addition to reactions between alkenes or alkynes, The carbon atom with the fewest hydrogen atoms linked to it receives the proton.

I would say that you would need 12 to have it be equal for this reaction to happen. I hope that this helped. :)
