Nitrogen gas is collected over water in a eudiometer. The volume of the nitrogen gas is 45.5 mL, the atmospheric pressure is 756.0 mm Hg, the water temperature is 24.0C, and the water level inside the eudiometer is the same as the level of water in the beaker.

(a) Calculate the pressure of the dry nitrogen gas. Bax your answer
(b) Calculate the volume of the nitrogen gas at STP.

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.

Where are the noble gases located in the periodic table? a. in the center b. on the left side c. in the upper right corner d. on the far right side

Can anyone explain 1. review your spectrometry data and use the known elements to identify the star's composition. which unknown elements make up this star? justify your element selections. 2. in parts i and ii of the lab, what happened to the electrons of each element to produce the different colors of light? explain your answers using important terms from the lesson and information provided in the laboratory. 3. stars composed of heavier (more massive) elements are often slightly older than stars made predominantly from hydrogen and helium. based on your data, is the newly discovered star a younger star? explain your answer.
