Answer:
The word dynamic is used to describe chemical equilibrium because even though the concentration of reactants and products remains constant, the reaction does not stop, but still continues with the rate of forward reaction equal to the rate of backward reaction. This is opposed to static equilibrium where there is no reaction at all.

It's actually made or gas and dust that can extend hundreds of millions of kilometers away from the coma. most comets actually have two tails a plasma tell made of ionized gas and a dust tail made of small solid particles.
after a volcanic eruption is the answer
Mudflows of volcanic eruptions are the most dangerous, and are called lahars
Answer:
Explanation:
From the question we are told that:
Edge length of the unit cell 
a)
Generally the equation for The relationship between edge length and radius is mathematically given by
Therefore
b)
From the question we are told that:
Density 
Edge length of 
Therefore Volume is given as
Generally the equation for Mass is mathematically given by
Therefore Molarity is given as
Finally The atoms in a unit cell is
