A balloon has a volume of 3.1 L at a pressure of 1.4 atm and a temperature of 33 ∘C. If the balloon is submerged in water to a depth where the pressure is 4.8 atm and the temperature is 15 ∘C, what is its volume (assume that any changes in pressure caused by the skin of the balloon are negligible)?

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.

The reaction: (ch3)3cbr + oh− → (ch3)3coh + br− in a certain solvent is first order with respect to oh−. in several experiments, the rate constant k was determined at different temperatures. a plot of ln(k) vs 1/t was constructed and the slope of the line was -1.10 x 104 k with a y-intercept of 33.5. what is the value for k at a temperature of 25°c?
