Answer: The tree died 9709.46 years before.
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 = 100
a - x = amount left after decay process =
a) to find rate constant
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) to know the age
The tree died 9709.46 years before.
Answer:
The rate of temperature change does not stay constant and decreases over time because the temperature difference decreases over time.
Explanation:
The temperature difference is due to Thermal Equilibrium
Answer:
133.34 g/moles
Explanation:
but to make life easy it could be 133.4 g/ moles as well
