Answer:
The volume will goes to decrease.
Explanation:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when pressure is going to increase the volume will goes to decrease and vice versa.
Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,
Now we will put the values in formula,
P₁V₁ = P₂V₂
15 atm × 10 L = 30 atm × V₂
V₂ = 150 atm. L/ 30 atm
V₂ = 5 L

experiment, they would have to prove their claim more than once, and they
assumed things before actually studying it. </span>
The chemical reaction involving Mg(OH)2 and HCl is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we see that for every 2 moles of HCl, 1 mole of Mg is
reacted.
Calculating for moles HCl:
moles HCl = 0.300 M * 0.215 L
moles HCl = 0.0645 mol
The moles Mg then is:
moles Mg = 0.0645 mol * (1 / 2)
<span>moles Mg = 0.03225 mol</span>
