The Mathematics of Chemical (Stoichiometry) major task of the chemist is to project how much product produced must have more value than the reactants The cost of the energy used in the reaction or the cost consideration. The Atom. (compounds) The “perfect reaction.” This is different from the actual yield, the amount one actually produces and measures Stoichiometry Flow Chart. Determine the mass of citric acid in the lemon juice, and then use the molar mass to find the moles Reduced parasitic losses (friction and heat transfer) relative to output. A balanced chemical equation provides a great deal of information in a very succinct Concise guides with explanations, step-by-step examples, videos, and lots of practice with solutions. Subscripts tell the number of atoms of each element in a molecule or compound. For elements that occur as molecules, use the molecular formula to find atoms/mol Subscripts and Coefficients Give Different Information. Protons, Neutrons, Electrons, & Mass Number. Coefficients tell the number of molecules or entities. Electron Solution: The formula of citric acid obtained by counting the number of carbon atoms, oxygen atoms, and hydrogen atoms is C6H8OMolar mass = (6 x) + (8 x) + (7 x) = g/mol. Large displacement, low speed – lower FMEP. Since the green ball is heavier, its atomic mass is larger, and therefore its molar mass is larger. A chemical engineer must be able to process is economical. The element on the left (red) has more atoms per gram To convert between amount (mol) and mass (g), use the molar mass (in g/mol). Diesel Engine Characteristics (compared to SI engines) Better fuel economy. Calculate the fraction of potassium chromate in the feed recovered as solid crystals, the ratio (kg recycle /kg fresh feed), the volumetric flow rate (m3/h) of the vapor effluent – Reaction Stoichiometry. Higher CRStoichiometry Theoretical Yield The theoretical yield is the amount of product that can be made – In other words itʼs the amount of product possible from stoichiometry. The Stoichiometry of Balanced Chemical Equations. To convert between amount (mol) and number of entities, use Avogadro’s num-ber (entities/mol). Overall lean, thermodynamically efficient. Large Diesels: f~% ~% ideal efficiency! stoichiometry The element on the left (green) has the higher molar mass because onlygreen balls are necessary to counterbalance the mass ofyellow balls.
