When a mixture of KI and KCl is heated repeatedly with `H_(2)SO_(4)`, iodine escapes completely and `K_(2)SO_(4)` is produced quantitatively. In case of such a mixture, it is observed that the mass of `K_(2)SO_(4)` is equal to the mass of the mixture of KI and KCl taken. what is the ratio of the masses of KI and KCl in this mixture?

When a mixture of NaCl and KCl is heated with conc. H_2SO_4 and K_2CrO_7 . The red gas obtained is

If the ratio of masses of CH_(4) and N_(2) in a gaseous mixture is 1 : 4 then what will be the ratio of number of molecules of them in the mixture ?

When a mixture of NaCl and NaBr is heated with H_(2)SO_(4) , the halogen components are liberated as their hydracids leaving Na_(2)SO_(4) as the residue. In an experiment, the mass of Na_(2)SO_(4) left is equal to the mass of (NaCl+NaBr) taken at the begining of the experiment. calculate the percentages of NaCl and NaBr in the given mixture.

A solid mixture of AgCl ad K_(2)Cr_(2)O_(7) is heated with conc. H_(2)SO_(4) and produces:

A solid mixture of AgCl ad K_(2)Cr_(2)O_(7) is heated with conc. H_(2)SO_(4) and produces:

31.3 gram mixture NaBr and NaCl treated with H_(2)SO_(4).28.4 gram of Na_(2)SO_(4) is produced. Then calculate the amount of NaCl and NaBr in the mixture.

31.3 gram mixture NaBr and NaCl treated with H_(2)SO_(4).28.4 gram of Na_(2)SO_(4) is produced. Then calculate the amount of NaCl and NaBr in the mixture.

When NaCl ( or ) KCl is heated with conc. H_(2) SO_(4) and solid K_(2)Cr_(2) O_(7) , we get -vapours
