The mass of methane is 1.117×10^17 g.
Given,
∆H°rxn =-802kj/mol
1Ej = 10^18 j =10^-3×10^18 kj
802kj of energy is released by 1 mol of CH4.
1kj of energy is released by 1/802 mol of CH4.
5600Ej of energy is released= 5600/802 mol of CH4
5600×10^18×10^-3 kj of energy is released
=5600 × 10^18 × 10^-3 /802 mol
=6.982 ×10^15 mol of CH4
We know,
the molecular mass of CH4 = 16 g
1 mol of CH4 = 16g
6.982×10^15 mol = 16 × 6.982 × 10^15 = 1.117×10^17 g
Hence, the mass of methane is 1.117×10^17 g.

The answer for the given question above is TRUE. Atoms whose valence shells do not normally match the inert configuration may achieve a lower energy state by combining with other atoms. I hope this answer helps.
The vital capacity will be 4600ml.
<h3>What is
vital capacity?</h3>
The highest amount of air a person can inhale following their maximal exhalation is known as their vital capacity. It is equivalent to the total of the inspiratory, tidal, and expiratory reserve volumes. It roughly corresponds to Forced Vital Capacity. A wet or conventional spirometer can assess a person's vital capacity.
Normal people have a 3 to 5-liter vital capacity.
It enables simultaneous inhalation of the greatest possible volume of clean air and exhalation of the greatest possible volume of stale air. So, by increasing gaseous exchange between the body's various tissues, it improves the amount of energy available for bodily function.
VC = TV₊IRV₊ERV
where,
VC = Vital capacity
TV = Tidal volume
IRV = inspiratory reserve volume
ERV = expiratory reserve volume
VC = 500 ₊ 3000 ₊ 1100
VC = 4600ml
Therefore, the vital capacity will be 4600ml.

Answer:
Alkanes with more than 3 carbons can show constitutional isomerism. They can be either linear or branched structures. This is categorized as chain isomerism. Butane is the smallest alkane to show such isomerism with 2 isomers.Alkanes with more than 3 carbons can show constitutional isomerism. They can be either linear or branched structures.
