A 15.0 atm pressurized 5.00 L cylinder refriegerated at 9.89°C is filled with an air mixture containing 30% helium, 30% diatomic nitrogen, and 40% nitrogen dioxide by volume. What is the partial pressure of each component and how many grams of each component are contained in the cylinder?

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
