Mary J. Bojan Chem 110 The balanced equation is central to problem solving 20 write the balanced chemical equation for the reaction (or process). make connections between experimentally measured properties and the balanced equation. In other words: Given information such as mass, volume, pressure and temperature, how can one determine quantities of moles/molecules ?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
