Got this question on my Grade 11 Chem Test (Chemical Bonding, Matter, etc)
It was a multiple choice. These are the answers I remember:
Red yellowish gas
Black powdery solid
One or two other answers but I forgot (Don't have the test back yet). I assume it was just testing our knowledge on similar properties. The properties in the answers are in reference to other chemicals (Ex. Black powdery solid - Lead).
What would the answer most likely be?
