Hidrogen gas is a diatomic gas, this is H2, which means that one molecule of gas has two atoms (every molecule of hydrogen gas consists in H2).
The particles in gases are the molecules, not atoms.
So, every molecule is a particle, and when you are told that you have 1 mole of hygrogen gas means that you have 1 mole of H2 molecules which is the same that 1 mole of particles.
Therefore, the answer is one mole.
Answer:
C
Explanation:
Wind is geological therefore it is geological weathering
Answer:
light with a high enough intensity
Explanation:
The symbol is U and its atomic number is 92
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature and moles.
Mathematically, P = 
where, k = proportionality constant
Also, formula for initial pressure and volume is as follows.

or, 
=
= 30 atm L
Now, we will calculate the value of
as follows.

= 
= 30 atm L
Hence, as
this means that it signifies that gas obeys boyle's law.
