Heat; rather, or change of the molecules to make them move faster
Answer: 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
Energy is the ability to do work
Answer:
16L
Explanation:
Data obtained from the question include:
V1 (initial volume) = 4L
P1 (initial pressure) = 4atm
P2 (final pressure) = 1atm
V2 (final volume) =?
Using Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follow:
P1V1 = P2V2
4 x 4 = 1 x V2
16 = V2
V2 = 16L
Therefore, her new lungs volume is 16L
Answer:
V = 25.7 L
Explanation:
To find the volume of Argon (Ar), you need to use the Ideal Gas Law equation. This looks like:
PV = nRT
In this formula,
> P = pressure (atm)
> V = volume (L)
> n = number of moles
> R = constant (0.0821 L*atm/K*mol)
> T = temperature (K)
While there is a different constant that can be used if you want to keep the pressure in mmHg, there is a more common constant used when the pressure is in atm. So, to find the volume, you need to (1) convert mmHg to atm (by dividing by 760) and then (2) calculate the volume (using Ideal Gas Law).
<u>(Step 1)</u>
600 mm Hg 1 atm
------------------- x --------------------- = 0.789 atm
760 mm Hg
<u>(Step 2)</u>
PV = nRT
(0.789 atm) x V = (0.825 mole)(0.0821 L*atm/K*mol)(300 K)
(0.789 atm) x V = 20.32
V = 25.7 L
