N₂ + 3 H₂ → 2 NH₃
number of moles of N₂ = 38 g / 28 g/mol = 1.357 mol
1 mole of N₂ gives 2 moles of NH₃
1.357 mol of N₂ will give ?? mole NH₃
= 2 x 1.357 = 2.7 mol NH₃
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
And I don't see any of the particles. so I can only answer the first one.
For waves:
speed = frequency x wavelength
speed = 3 x 10⁸
frequency = 9192631770 Hz
wavelength = 3 x 10⁸ / (9192631770)
wavelength = 0.033 meters
This wavelength lies in the region of microwaves.
