Hi, I’m Will Comar, and welcome to Study
Hall: Chemistry, presented by Arizona State
University and Crash Course!
The world is built on chemistry. It’s in
the medicines we take, the air we breathe,
and the food we cook. Life is possible because
of the relationships between the tiniest of
particles, and we humans participate in life-giving
chemical processes, like cellular respiration,
all the time. Chemistry reveals the connections
between us and the reactions that drive change
in the world in a pretty amazing way.
But, it is a subject that can be a stumbling
block for some of us. It’s well known for
being complicated and full of weird rules.
And sure, there’s a lot to remember, and
it can definitely become overwhelming.
But overwhelming doesn’t mean impossible.
So, whether you’re new to chemistry or have
taken a few classes on it before, this 15-episode
series will bring some clarity to the subject,
and also some excitement and fun!
We’ll walk through the difficult bits at
our own pace, and point out some hacks to
make things seem less intimidating.
Besides, we all have the ability to be great
at chemistry, because humans are wired to
seek new ideas, problem solve, and find connections
between things.
Chemistry relies on all of this, and the way
to master it is to tap into these qualities
and use them for our advantage.
In this series, we’ll make our way through
a lot of the foundational topics of chemistry,
especially the ones that are famous for being
challenging.
In the first half, we’ll cover the different
kinds of chemical reactions, as well as how
to balance them. We’ll debunk alchemy, learn
to predict products, and find the solution
for making great sweet tea.
We’ll use some funky Ion Vision glasses
to talk about ionic equations, and we’ll
take an in-depth look at the mole. These are
our keys to the rest of chemistry, and once
we’re more familiar with them, we can use
them to unlock more complex material.
The second half of this series will apply
these key subjects to things like stoichiometry
and acid-base relationships.
We’ll tell you how these chemicals work,
so we can build our understanding of chemistry
instead of just memorizing formulas.
Throughout the episodes, we’ll also examine
where we see examples of chemistry in real life.
Like I mentioned, the world is built
on chemistry, so we have to know how it works
outside the classroom.
Human-centric chemistry, especially when it
involves the environment, will often come
into play as we go. We all have a responsibility
to understand and contribute to the world
around us, and learning about the impact we
make can empower us to make positive changes.
So, join me for our first episode, Chemical
and Physical Change.
See you all there!
