Finally, the curriculum culminates in the study of chemical reactions and stoichiometry. A chemical reaction is the process by which substances change into new substances. At the 10th-grade level, students learn to classify these reactions—synthesis, decomposition, single and double replacement, and combustion. More importantly, they learn the law of conservation of mass, which states that matter is neither created nor destroyed. This law is applied through stoichiometry, the mathematical calculation of reactants and products. Stoichiometry teaches students that chemistry is quantitative; it requires precise measurement and balancing of equations to predict the outcomes of experiments. : Essential for clearly seeing molecular structures and
