To be honest, that should be alright. Writing about the formation of the black solid should get you 1 mark and reddish brown fumes should get you 2 marks. The total marks for the question is 3, so I wouldn't worry much about it. :)

reddish brown is one mark and fumes is another mark. Both of them are different observations. Reddish brown is colour change, so one mark. Black solid is colour change so one mark. Fumes is an added observation. So it should be another mark. also, while practicing, i think i came across a question where reddish brown fumes scores 2 marks.
