Accepted Answer
1. Commercial chemical process: A chemical process designed to produce a useful product on a large scale. Examples include the Haber process for producing ammonia and the cracking of petroleum to produce gasoline and other fuels.
2. Dimensional analysis: A method of checking the validity of an equation by comparing the units of the quantities on each side of the equation. For example, the equation "v = u + at" has units of m/s on both sides, so it is dimensionally correct.
3. Stoichiometry: The study of the quantitative relationships between reactants and products in chemical reactions. For example, the stoichiometry of the reaction between hydrogen and oxygen to produce water is 2H2 + O2 → 2H2O.
4. Stoichiometry ratio: The ratio of the number of moles of reactants to the number of moles of products in a chemical reaction. For example, the stoichiometry ratio of the reaction between hydrogen and oxygen to produce water is 2:1.
5. Stoichiometry coefficient: A number that precedes a chemical formula in a chemical equation to indicate the number of moles of that substance involved in the reaction. For example, the stoichiometry coefficients in the equation 2H2 + O2 → 2H2O are 2 for H2, 1 for O2, and 2 for H2O.
