Scintillatium has a halflife of 16 minutes. if a sample has 800 grams, find a formula for its mass after t minutes.

Halflife is the time needed for a radioactive molecule to decay half of its current mass. If t is the time elapsed, the formula for the halflife would be:
final mass= original mass *

If you put the information of the problem into the formula, the equation will be:
final mass= original mass *
final mass= 800g *

They are all decomposition reactions.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
