If the uncompressed has in the above system has a volume of 300.0 mL at a pressure of 20.0 kPa what is the volume of the gas when it is compressed to a pressure of 25.0 kPa

240 ml

Explanation:

Initial Volume V1 = 300 ml

Initial Pressure P1 = 20.0 kPa

Final Pressure P2 = 25 kPa

Final Volume V2 = ?

These quantities are related by boyles law which is given as;

V1P1 = V2P2

Making V2 subject of interest;

V2 = V1P1 / P2

Upon inserting the values;

V2 = 300 * 20 / 25

V2 = 240 ml

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
