Answer 1

The equation is 4AgNO3-----> 2Ag2O + 4NO2 + O2.

B The brown gas is nitrogen dioxide ( NO2).

C The colourless gas is oxygen(O2).

A The metal nitrate is silver nitrate (Ag2O).

D The yellow precipitate is silver iodide.
The reaction for this is
KI + AgNO3 ------> KNO3 + AgI.

Hope my answer is correct.
