I can predict the product of a chemical reaction based
upon the reaction type.
I can recall the balancing of chemical equations in terms
of atoms, molecules and moles.
I can contrast quantitative and qualitative analysis.
I can write balanced ionic and net ionic equations.
I can calculate the quantities of reactants and/or
products involved in chemical reactions, using
gravimetric stoichiometry.
I can calculate the quantities of reactants and/or
products involved in chemical reactions, using solution
stoichiometry.
I can calculate the quantities of reactants and/or
products involved in chemical reactions, using gas
stoichiometry.
I can explain chemical principles (conservation of mass)
using quantitative analysis. (precipitate calculations)
I can identify limiting and excess reagents in chemical
reactions.
10 I can define theoretical yields and actual yields.
11 I can calculate % error and explain the discrepancy
between theoretical and actual yields.
12 I can draw and interpret titration curves, using data from
13
titration experiments involving strong/weak monoproctic
acids and strong/weak monoproctic bases.
I can identify equivalence points on titration curves and
differentiate between the indicator end point and the
equivalence point.
