Consider the reaction and based on the reaction answer the questions that follow :
`(NH_(4))_(2)Cr_(2)O_(7) overset("Heat")to N_(2(g))+4H_(2)O(g)+Cr_(2)O_(3)`
Calculate:
The volume in litres or dm of `N_(2)` evolved at S.T.P

Text Solution

Verified by Experts

From the given chemical reaction

Volume of nitrogen obtained from 252 g of `(NH_(4))2Cr_(2)O_(7)` = 22.4 litres
`therefore` Volume of nitrogen obtained from 63 g of `(NH_(4))_(2).Cr_(2)O_(7)=22.4/(252)=63`
= 5.6 litres at S. T.P.
