Answer:
A methane molecule is made from one carbon atom and four hydrogen atoms. Carbon has a mass of 12.011 u and hydrogen has a mass of 1.008 u. This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams.
メタン分子は、1つの炭素原子と4つの水素原子から作られています。炭素の質量は12.011uで、水素の質量は1.008uです。これは、1つのメタン分子の質量が12.011 u +（4×1.008u）、つまり16.043uであることを意味します。これは、1モルのメタンの質量が16.043グラムであることを意味します。^>^
The possible structures with 6-C Chain and 1 double bond i.e. the isomers are 2-methylhex-2-ene , 3-methylhex-2-ene , 4-methylhex-2-ene , 5-methylhex-2-ene , 2-methylhex-3-ene , 3-methylhex-3-ene , 4-methylhex-3-ene , 5-methylhex-3-ene , 2-methylhexene , 3-methylhexene , 4-methylhexene , 5-methylhexene .2-methylene hexane , 3-methylenehexane .
These all are functional group isomers.
<h3>isomers :</h3>
same molecular formula but different physical and chemical properties .
<h3>Positional isomers :</h3>
same molecular and chemical formula but different in position of the functional group .it is a structural isomerism .
<h3>functional isomers :</h3>
same molecular formula but different functional groups attached to the main ring.

Answer:
The Moon has an atmosphere.
Explanation:
The Moon has an atmosphere, but it is very tenuous. Gases in the lunar atmosphere are easily lost to space. Because of the Moon's low gravity, light atoms such as helium receive enough energy from solar heating so that they escape in just a few hours.
a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction.
It’s about drive it’s about power
