Un globo meteorológico se llena con 15.0 L de helio a una temperatura de 25°C y una presión de 685 torr. ¿Cuál es la presión del helio en el globo en la atmosfera superior cuando la temperatura es -35°C y el volumen se vuelve 34000 mL?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
