Chemistry is the study of matter and energy, focusing on substances and their reactions. Chemists can work in labs, do fieldwork, or develop theories and models on computers. Many fields, including medicine and engineering, use chemistry to understand the world better.
Chemistry is the study of matter, its properties, and interactions with energy. Chemistry is related to other sciences like physics and biology and uses the scientific method. Studying chemistry helps us understand cooking, digestion, and even how medications work.
General chemistry topics include things like atoms and molecules, how substances react, the periodic table, and the study of different compounds.

Stoichiometry is the branch of chemistry that deals with the relationship between the relative quantities of substances taking part in a chemical reaction

Reaction stoichiometry gives us the tools in chemistry to figure out the relative amounts of reactants and products in a chemical reaction. We can also use stoichiometric tools to figure out the number of atoms present in a compound or amount of substance or solute in a solution, respectively called composition and solution stoichiometry. We will focus our discussion on reaction stoichiometry.
