What is the chemical formula of anthrax?

Answer 1

Anthrax is really a bunch of spores of a microbe called bacillus anthracis. These spores are very resistent to drying out and harsh environmental conditions, making them survive for long times. Once these spores settle and grow into the bacterium, this bacterium releases an anthrax toxin that can cause life threatening pneumonia if the bacterium/spores were inhaled and settled in your lung.

Answer 2

Anthrax is a living thing (bacteria- Bacillus Anthracis). Not a chemical - so it does not have a chemical formula.
