Lab Quiz A : Types of Chemical Reaction Lab
1a.When you heated up (decomposed) copper (II) carbonate, what was the gas that was produced?
Write it's chemical formula (not chemical name) _____________.
1b. What happened to the match (write your observation(s) ) to indicate that it was the gas (the one you stated in Question 1a)?
____________________________________
2. In the Synthesis section, you exposed copper wire to a flame. Give the chemical formula of the product ________________ and what is it's phase _______________ and color _______________.
3. In the space below, write the balanced complete (sometime called molecular) chemical reaction (that includes phase) for the Double Replacement you ACTUALLY did in the lab. (you DO NOT have to do a net ionic reaction to it.)
4. On the back of this sheet, show the balanced complete chemical reaction and all work to show how one gets the net ionic reaction for the 2nd reaction in the Single Replacement section of this lab. (It is NOT the reaction with Hydrochloric acid).
5. On the back of this sheet, rewrite you answer to the following question in the Question section:
"Part II: Write the balanced complete chemical equation for the following reactions. Then do a net ionic reaction on the reaction (showing all appropriate work).
3. Chlorine gas (elemental form) is bubbled through a solution of potassium bromide."
