The gas evolved on heating (NH_(4))_(2)Cr_(2)O_(7) is :

The gas evolved on heating CH_(3)MgBr in methanol is :

The gas evolved on heating CH_(3)MgBr in methanol is :

Which gas is evolved when NaHCO_(3) is heated ?

Which gas is evolved when NaHCO_(3) is heated ?

Na_(2)CO_(3) have water of crystallisation and its formula is Na_(2)CO_(3)*xH_(2)O .If 2.32g" of Na_(2)CO_(3)*xH_(2)O is heated then it loose "1.26g" of water,the value of "x" is assume all water of crystalline are removed when Na_(2)CO_(3)*xH_(2)O is heated

AgCl when heated with Na_(2)CO_(3) gives
