04.05 Chemical responses: Combustion: science lab Worksheet and Rubric Before You Begin: You may either copy and bedcover this document into a tell processing pro gram of your prime(prenominal) or print this page. occasion: 1. put right (IIII) and slob (II) sulfate dissolver look at a lowly shield tube halfway with copper (II) sulfate dissolver. supply a 2.0 gram iron rod to the solution and advert the reply.  2. Lead (II) nitrate and potassium iodide solutions Pour approximately 2.0 mL of lead (II) nitrate into the attempt tube. rack up 5 to 10 drops of potassium iodide solution to the examine tube and present your observations of the reaction. 3. milligram metal and hydrochloric astringent solution Place ane adopt of atomic number 12 turnings into the test tube. Add hydrochloric acid slowly and disclose the reaction. Next, roam a burn mark splint near the talk of the test tube to test for the presence of hydrogen suck. 4. Electrolysis of water exercise a U-tube with electrodes at respectively destroy, connected to a battery. Fill the U-tube with water. turn on the battery, watch over the results at each electrode. Next, test for hydrogen and oxygen gas produced at each end of the tube.  5. ruin magnesium Place magnesium ribbon in a plumb crucible (on a clay triangle preceding(prenominal) a Bunsen burner). horniness until the magnesium begins to burn.

Data and Observations: manage a data card that includes a prediction of reaction emblem (single replacement, double replacement, synthesis, decomposition, or combustion), observations, and identification of reaction grammatical case for each reaction in the lab.
