Answer
The particle theory is used to explain the properties of solids, liquids and gases. The strength of bonds (attractive forces) between particles is different in all three states.
Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.
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
Ecosystems: Coral Reef, Savanah
Living: In coral reef; clown fish In Savanah: Emu
Nonliving: In Coral reef: Water In Savanah: sun
