Learning Objectives: • Explain the relationship between mass, molecular weight, and numbers of atoms or molecules and perform calculations deriving these quantities from one another • Perform mass-to-mass stoichiometric calculations via conversions to moles • Identify the limiting and excess reagents in a chemical reaction • Calculate the theoretical, actual and percent reaction yield • Define Avogadro’s number and describe the mole quantification of matter • Explain relation...

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...

Experiment for Diffusion? - correct answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - correct answer 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over ...
