About the course

Chemistry is known for being a difficult subject, but it doesn’t have to be daunting. That’s why I am making a series to go in depth about core chemistry concepts. Today, we will be learning about different classifications of chemical reactions and how to represent them using balanced chemical equations. Balancing equations can seem overwhelming at first, but they can be fun once you get a grasp on it. Don’t worry, I will be walking you through how to balance an equation step-by-step so that even if you’ve never heard the term “chemical equation” before, you’ll be able to follow along. We will look at three different kinds of chemical reactions and practice our balancing skills with a multitude of different kinds of equations.

I attended the Packer Collegiate Institute in Brooklyn, NY where I was able to explore my multiple different passions through engaging classes and fun clubs. I am currently on a gap year but am excited to attend Northwestern University next fall with an intended major in Environmental Chemistry.

Throughout my time in high school, I tutored many students in chemistry. As early as 10th grade, my chemistry teacher recommended me to the school’s peer tutoring program because she saw how deeply I was grasping and understanding the information being taught. I have worked with students on homework, test prep, and lab report editing.

In addition to tutoring high school chemistry, I have worked with kindergarteners and first graders on reading skills and comprehension, so I feel confident working
