04. 05 Chemical Reactions: Combustion: Lab Worksheet and Rubric Before You Begin: You might either duplicate and insert this document into a expression processing program of your choice or print this page. Procedure:

1 . Iron (IIII) and water piping (II) sulfate solution
Fill a small test conduit halfway with copper (II) sulfate answer. Add a installment payments on your 0 gram iron fly fishing rod to the answer and observe the reaction. 


2 . Business lead (II) nitrate and potassium iodide solutions
Pour about 2 . 0 milliliters of lead (II) nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your findings of the effect. 


3. Magnesium steel and hydrochloric acid solution
Place one details of magnesium turnings in the test conduit. Add hydrochloric acid slowly and gradually and observe the reaction. Up coming, place a using splint near the mouth in the test conduit to test pertaining to the presence of hydrogen gas. 


4. Electrolysis of water
Use a U-tube with electrodes at each end, connected to a battery. Fill the U-tube with drinking water. Turning on the battery, observe the results each and every electrode. Subsequent, test for hydrogen and oxygen gas produced each and every end of the tube. 


5. Burning magnesium
Place magnesium (mg) ribbon in a clean crucible (on a clay triangle above a Bunsen burner). Heat until the magnesium begins to burn. Data and Findings:

Complete a info table which includes a prediction of reaction type (single replacement, double replacement, synthesis, decomposition, or combustion), observations, and identification of reaction type for each response in the laboratory. (10 points) Reactants

Prediction of Reaction Type

Findings

Reaction Type

Conclusion:

1 . Write a well-balanced equation for every single reaction noticed in this lab. (10 points)



2 . If you were to measure the mass of magnesium and hydrochloric acid solution before incorporating them in the test tube, how would that mass compare to the mass of reactants kept in the evaluation tube following your...
