Visualizing Concepts
The following boxes represent aqueous solutions containing a weak acid, HA and its conjugate base, A-. Water molecules, hydronium ions, and cations are not shown. Which solution has the highest pH? Explain. [Section]
10/10 Chapter 4- Stoichiometry and Chemical Reactions (Cont.) Stoichiometry 1) Molar ratio of reactants and products to each other 2) Reactant stoichiometry when burning propane is 1 propane to 5 oxygen molecules 3) Propane is equal to 3 CO after burning 2 4) You need to know the number of moles/molecules for this to work. Anything else is not applicable. a) For example, if you are given mass, you need to turn that into moles by dividing by Molar Mass, and then you find the moles of the other given element and turn that back into mass by multiplying by Molar Mass. b) Example
