When chemicals react, they do so in specific, fixed ratios. Stoichiometry is the part of chemistry that deals with these quantitative relationships. It all starts with a balanced chemical equation.

You encounter the three main states of matter (solid, liquid, gas) every day. The key difference between them is how their particles are arranged and how much energy they have.

You'll often hear about how fast reactions happen and where they end up. Kinetics is about the "how fast," while equilibrium is about the "where it ends."

You'll explore two related but distinct areas: Thermodynamics and Electrochemistry. Thermodynamics focuses on energy changes and spontaneity, while electrochemistry deals specifically with electron transfer reactions (redox reactions) and their energy transformations.
