Answer: The rate constant is
Explanation ;
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = ?
t = age of sample = 4.26 min
a = initial amount of the reactant = 2.56 mg
a - x = amount left after decay process = 2.50 mg
Now put all the given values in above equation to calculate the rate constant ,we get



Thus rate constant is [tex]0.334s^{-1}
Answer:0.58 atm
Explanation:see attached photo
Answer:
Your notation is a bit confusing, let me write it more clearly.
Explanation:
( Temperature in °F − 32) × 5/9 = Temperature in °C
The magnitude of the orbital angular momentum of the electron is doubled when the radius of the electron orbit increases by a factor of four.
<h3>
What is orbital angular momentum?</h3>
The orbital angular momentum is the sum of angular momenta of all electrons, it is the rotational analog of the linear momentum.
The formula of angular momentum

Thus, the magnitude of the orbital angular momentum of the electron is doubled when the radius of the electron orbit increases by a factor of four.
