You observed several chemical reactions throughout the lessons in this unit. And we discussed them in class. A. List 5 signs (observations) that indicate a chemical reaction has occurred. B. Give 2 specific examples from what was discussed in class.

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
