A Los Angeles class nuclear submarine has an internal volume of 1.1x107 liters at a pressure of 1.250 atm. If a crewman were to open one of the hatches to the outside ocean while it was underwater, causing the internal pressure to increase to 5.75 atm, what would be the new volume of the air inside the submarine?

2.39 x 10⁶ Liters

Explanation:

Boyle's Law => P₁V₁ = P₂V₂

P₁ = Initial Pressure = 1.250atm   P₂ = final pressure = 5.75atm

V₁ = Initial Volume = 1.1 x 10⁷ L    V₂ = ? final volume

V₂ = P₁V₁ / P₂ = (1.25atm x 1.1 x 10⁷L)/(5.75atm) = 2.39 x 10⁶ Liters

the answer is a and have a great day

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
