Science is applied in all parts of our lives. Firefighters use science by knowing what causes fire and what circumstances are necessary for a fire to occur naturally. for example knowing the chemical composition of hay required in order for it to self ignite on fire helps to take measurements and prevent unwanted fires.
<span>It is transferring from particle to particle and travels that way. But each transfer is not 100% and it gradually dies out. So, in other words, as the distance increases </span>the intensity of the sound wave decreases.

Nitric acid(HNO3) is a strong acid so most of its component will dissociate into an ion form. When dissolved into water, nitric acid will have this reaction
HNO3= 1 H
+ NO3
For every 1 mol of HNO3, there will be 1 mol of H+ ion and NO3- ion formed, which makes a total of 2 ions(degree of dissociation = 2).
Then for 2 moles of HNO3 it would be: 2 moles * 2= 4 moles of ion
