A3.0 l container holds a sample of hydrogen gas at 300 k. if the temperature decreases to 100 k and the pressure remains constant, what will the volume be? (points : 3) 0.1 l 0.3 l< -- i thinks its this 1.0 l 9.0 l

At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 = 100 x 3.0 / 300

V2 = 1.0 L

Hope this answers the question. Have a nice day.

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.
