Number of salts among the following that will give metal on heating is:
`Zn(NO_(3))_(2),AgNO_(3),Cu(NO_(3))_(2),Hg(NO_(3))_(2),pb(NO_(3))2`

Number of salts among the following that will give metal on heating Zn(NO_(3))_(2),AgNO_(3),Cu(NO_(3))_(2),Hg(NO_(3))_(2)

On strong heating Pb(NO_(3))_(2) gives:

How many of the following will give O_(2) on heating ? KMnO_(4),K_(2)Cr_(2)O_(7),ZnO,Na_(2)O, PbO_(2),Pb_(3)O_(4),Pb(NO_(3))_(2),NH_(4)NO_(3)

Find the number of compounds which liberate NO_(2) gas as one of the products on heating NH_(4)NO_(3),NH_(4)NO_(2),Ca(NO_(3))_(2),Zn(NO_(3))_(2),Hg(NO_(3))_(2),AgNO_(3),LiNO_(3),Al(NO_(3))_(3),KNO_(3) . [If your answer is 4 then write the answer as 0004.]

Balance the following equation by oxidation number method Zn+HNO_(3) to Zn(NO_(3))_(2)+NH_(4)NO_(3)+H_(2)

Arrange the following in order of decreasing N - O bond length NO_(2)^(-),NO_(2)^(-),NO_(3)^(-)
