66 views7 pages

Document Summary

3. 7 amounts of substances in a chemical reaction: can use conversion factors to go from the moles of one product or reactant to another. Use this to convert from moles of reactant to moles of product or vice versa, for example. Smallest result will come from limiting reactant: theoretical yield of product: the maximum amount of product that can be obtained by a reaction from given amounts of reactants, calculated with stoich. Actual yield can be less (one reason is that many reactions stop before reaching completion making a mixture of products and reactants: percent yield=(actual yield/theoretical yield)x100% 4. 1 ionic theory of solutions and solubility rules electrolytes and. Nonelectrolytes observing the electrical conductivity of a solution strong and. Ionic solids that dissolve in water are generally electrolytes. Some molecular substances can be electrolytes such as hcl: non-electrolyte: a substance that dissolves in water to give a nonconducting or very poorly conducting solution.
