Higher, they have more energy so they move faster
Explanation:
Formula to calculate how many particles are left is as follows.
N = 
where,
= number of initial particles
l = number of half lives
As it is given that number of initial particles is
and number of half-lives is 3.
Hence, putting the given values into the above equation as follows.
N = 
=
= 
or,
Thus, we can conclude that
particles of radioactive nuclei remain in the given sample.
In five hours we've gone through 5 half lives so the answer is:
particles
The reaction of chlorine
gas with solid phosphorus produces solid phosphorus pentachloride
