Putting it all together – Stoichiometry ws 4
General Directions:
- Predict the products, include states of matter, and write a balanced equation for each of the following reactions. Do not forget BrINClHOF (Mrs. B’s classes) or HONClBrIF (Mrs. S’s class). For single replacement reactions, refer to the activity series table provided to determine if a reaction will take place. (Remember, everyone likes to trade up.) If no reaction takes place, write N.R. (no reaction).
- On the line in front of the problem number, classify the type of reaction by indicating S for synthesis or combination; C for combustion; D for decomposition; SR for single replacement, DR for double replacement, or NR for no reaction.
- Follow the specific directions provided for each problem set. For each stoichiometry problem, you must show your work by using dimensional analysis, labeling, and circling your answer. All calculations must be shown to receive credit.
Problem set A (#1-10). Follow the directions for steps 1 and 3. Then select 3 problems of your choice in this set and use stoichiometry to determine the limiting reactant. Circle the limiting reactant and use the limiting reactant to calculate how much precipitate could be formed. (This is the theoretical yield.) Show your work.
