A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 273.kPa. The piston is now pushed down, compressing the gas, until the gas has a final volume of 4.90L. Calculate the final pressure of the gas. Be sure your answer has the correct number of significant digits.

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.
