Geochemistry

You start your week with an Intro to Geochemistry lecture, covering the fundamental composition of Earth's crust. Later, in your General Chemistry lab, you're tasked with precise pH measurements, using a digital meter and calibration solutions. You briefly ask your TA for a quick tip on standardizing the buffer. After class, a quick workout at the campus gym helps clear your head. You realize you left your scientific calculator in your dorm just as the professor announces a pop quiz for tomorrow, causing a minor scramble to retrieve it.
