Answer:
Hello dear,
● Benzene to benzaldehyde -
There are several ways to convert benzene into benzaldehyde.
1) Riemer-Tiemann reaction -
- In this reaction, benzene is converted to benzaldehyde with the help of CHCl3 & NaOH.
C6H6 ---> C6H5-CHO
Catalyst - CHCl3 & NaOH
2) Gatterman-Koch reaction -
- In this reaction, benzene is converted to benzaldehyde with the help of CO/HCl & AlCl3/CuCl.
C6H6 ---> C6H5-CHO
Catalyst - CO/HCl & AlCl3/CuCl

Explanation:
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:
