Answer: 29.0 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) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for decomposition of 80 % of reactant
The age of a suspected vintage wine that is 20 % as radioactive as a freshlybottled specimen is 29.0 years
<u>The S.I unit for the given term:</u>
Mass is expressed in kilogram (kg)
temperature is expressed in kelvin (K)
Time is expressed in seconds (s)
Current is expressed in ampere (A)
<u>Explanation:</u>
<u>Current: </u>
The current can be defined as the electric charge flow in the surface (means ratio of charge per unit time). It is measured in ampere (A)
<u>Temperature: </u>
Kelvin (K), the general temperature unit in the international standard units system. The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero, a temperature at which all thermal movements end with a classic description of thermodynamics.
<u>Mass: </u>
Mass is both a feature of the objects weight and its resistance measurement to accelerate under the influence of pure force. The mass of the object also determines the gravitational force. The basic unit of mass is kilogram (kg)
<u>Time: </u>
Time is the measurement of how much distance the objects takes to travel from one to another (speed). It is expressed in seconds (s).
