Answer:
132.17 g
Explanation:
The reaction given , in the question is -
CH₄ (g ) + 4 S ( g ) ---> CS₂ ( g ) + 2H₂S ( g )
From the reaction , 4 mole of S is required for the production of 1 mole of CS₂ .
since ,
Moles of CS₂ = given mass of CS₂ / Molecular weight of CS₂
Since ,
the Molecular weight of CS₂ = 76
Given , mass of CS₂ = 72.57 g
Moles of CS₂ = 72.57 / 76 = 0.95 mol
Since ,
The yield is 92.0 % .
Moles of S required = 4 * 0.95 mol / 0.92 = 4.13 moles
Mass of S required = 4.13 * 32 = 132.17 g .
The reaction that best describes the change of aniline into phenyl isocyanide is
<span>C6H5NH2 + CHCl3 + KOH → C6H5NC + 3KCl + 3H2O
</span>
This is basically a characteristic reaction of the primary amines. <span> from the above reaction, we can see that aniline on carbyl amine reaction gives phenyl iso-cyanide.</span>
The first one is 2
The second is 1
The third is 6
And the fourth is 3
