NH4Cl is a dense white solid and NCl3 is a yellow explosive liquid

lead nitrate because it liberates nitrogen dioxide on heating

lead nitrate reacts with dil hcl to give PbCl2 which is soluble in in hot water but insoluble in cold water

you can't write pinkish metal deposit as the cathode is already pinkish brown and hence deposit would not be seen

so just mention that the cathode increases in size

ca: 2,8,8,2

P:2,8,5

correction : Al+3+3e 

u have written2e

it is name the following so SO2 will be the answer.no observations and tests required

16.5 to 0.0165
