Precipitation reactions are those reactions in which two aqueous solutions, when mixed, react to form a solid. The solid thus formed is known as a precipitate. Thus, a precipitate is an insoluble solid (recall that an insoluble substance is one which does not dissolve). ... We have defined precipitates as insoluble solid

Answer:
<h3>The answer is 223.0 cm³</h3>
Explanation:
To find the volume when the pressure is at 202.6 kPa we use Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 99.3 kPa = 99300 Pa
V1 = 455 cm³
P2 = 202.6 kPa = 202600
So we have
We have the final answer as
<h3>223.0 cm³</h3>

Then the acid would react with other molecules either in the atmosphere on a surface it's touching. If the acid is strong enough, it could corrode some of that surface, God forbid it's living human tissue.
Or the acid can release a toxic byproduct into the air.
