Limiting reactants - Study guides, Class notes & Summaries

Endothermic Absorbs heat, requires hear for the reaction Law of Conservation of Mass Matter is not created nor destroyed in any chemical or physical change, ergo total amount of matter in reactants = total amount of matter in products Mole-mole factors a conversion factor that relates the number of moles of two compounds derived from the coefficients in an equation Limiting reactant the substance that controls the quantity of product that can form in a chemical reaction Excess reactant a rea...

Straighterline CHEM101 Final Exam | Latest Version | 2024/2025 | Rated A+ What is the empirical formula of a compound with the molecular formula C6H12O6? CH2O How do you calculate the number of moles in 5 grams of sodium chloride (NaCl)? Divide the mass of NaCl by its molar mass. Describe the difference between an ionic bond and a covalent bond. An ionic bond involves the transfer of electrons between atoms, creating charged ions, while a covalent bond involves the sharing of ...
