Answer:
1. NaN₃(s) → Na(s) + 1.5 N₂(g)
2. 79.3g
Explanation:
<em>1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN₃) into solid sodium and gaseous dinitrogen.</em>
NaN₃(s) → Na(s) + 1.5 N₂(g)
<em>2. Suppose 43.0L of dinitrogen gas are produced by this reaction, at a temperature of 13.0°C and pressure of exactly 1atm. Calculate the mass of sodium azide that must have reacted. Round your answer to 3 significant digits.</em>
First, we have to calculate the moles of N₂ from the ideal gas equation.

The moles of NaN₃ are:

The molar mass of NaN₃ is 65.01 g/mol. The mass of NaN₃ is:

 
        
             
        
        
        
Answer:
 the frequency of photons 
Explanation:
Given:  first ionization energy of 1000 kJ/mol.
No. of moles of sulfur = 1 mole

We know that plank's constant 

Let the frequency of photons be ν
Also we know that ΔE = hν
this implies ν = ΔE/h 


Hence, the frequency of photons 
 
        
             
        
        
        
Yes, the law of thermodynamics, or Law of Conservation of Energy
        
             
        
        
        
Hey there:
Correct answer is : 
(b) NaNH₂
