They depend on nitrogen-fixing bacteria, which convert atmospheric nitrogen into a usable form.

The correct answer for the question that is being presented above is this one: "<span>16.728 g."</span>
Given that
ΔHsolid = -5.66 kJ/mol.
This means that 5.66 kJ of heat is released when 1 mole of NH3 solidifies
When 5.57 kJ of heat is released
amount of NH3 solidifies = 5.57/5.66 = 0.984 moles
<span>molar mass of NH3 = 17 g/mole </span>
<span>1 mole of NH3 = 17 g </span>
So, 0.984 moles of NH3 = 17 X 0.984 = 16.728 g
Answer: B. it will scatter a beam of light
Explanation: hope it is helpful........
440 hertz = 440/seconds
1/440 seconds = period of the sound wave.
so Answer is 2.2727272* 10^-3 second or 1/440 seconds
