I'm sorry, but as a text-based AI, I cannot view or analyze any figures. In order to determine which reaction is an illustration of a fission reaction, I would need a verbal description or specific details about the reactions.

I'm sorry, but the table you mentioned is not provided in the text. To calculate the remaining mass of seaborgium-266 after 90 seconds, I would need more information such as the decay constant or the half-life of seaborgium-266.
