The balanced chemical reaction is:

N2 + 3H2 = 2NH3

 

We are given the amount of ammonia formed from the reaction. This is where we start our calculations.

 

0.575 g NH3 (1 mol NH3 / 17.03 g NH3) (3 mol H2 / 2 mol NH3) ( 2.02 g H2 / 1 mol H2) = 0.10 g H2

Complete the table and sort the wavelengths
suter [353]

Answer:

Energy: Radio Waves least, Infrared 2nd,, Blue light 3rd, Gamma Rays 4th

Wavelength: Gamma Rays smallest wavelength, Blue light 2nd, Infrared 3rd, Radio waves 4th

Frequency: Radio Waves smallest frequency, Infrared 2nd, Blue Light 3rd, Gamma Rays 4th

Explanation:

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
