If a sample of C-14 initially contains 1.5 mmol of C-14, how many millimoles will be left after 2255 years?

millimoles will be left after 2255 years.

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  

a - x = amount left after decay process  

a)   of carbon = 5730 years

b) millimoles left after 2255 years

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
