Answer: Option (B) is the correct answer.

Explanation:

In a molecule of N_{2}H_{4}, there are 2 nitrogen atoms and 4 hydrogen atoms.  

In a molecule of Al(OH)_{3}, there are one aluminium atom, three oxygen atoms, and three hydrogen atoms.

In a molecule of (NH_{4})_{2}SO_{4}, there are 2 nitrogen atoms, 8 hydrogen atoms, one sulfur atom and 4 oxygen atoms.

In a molecule of NH_{4}NO_{3}, there are 2 nitrogen atoms, 4 hydrogen atoms and 3 oxygen atoms.  

Therefore, we can conclude that out of the given options Al(OH)_{3} is the molecule which contains the smallest number of hydrogen atoms.

KengaRu [80]

Answer:

False

Explanation:

Heres what its made of:

The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.
