A small plastic cup is floating in a pan of water. Inside the cup is one quarter. For an experiment, students take turns adding quarters to the cup one quarter at a time. Making observations after each quarter is added to the cup, the students will notice something about the water level in the pan. What do they notice about the water level? A: The cup will sink

B: The cup will go up

C: The level will go down

D: The level will remain the same

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
