Solid ammonium dichromate (relative mole...

Solid ammonium dichromate (relative molecular mass = 252) on heating decomposes as follows :
`(NH_(4))_(2)overset(Delta)toN_(2)+Cr_(2)O_(3)+4H_(2)O`
Calculate the volume of nitrogen at S.T.P., that will be evolved when 31.5 g ammonium dichromate is heated.

Text Solution

AI Generated Solution

To solve the problem of calculating the volume of nitrogen gas evolved from the decomposition of ammonium dichromate at STP, we can follow these steps: ### Step 1: Write the balanced chemical equation The decomposition of ammonium dichromate can be represented as: \[ (NH_4)_2Cr_2O_7 \xrightarrow{\Delta} N_2 + Cr_2O_3 + 4H_2O \] ...
