Introduction: There are several types of chemical reactions. Those reactions include synthesis, decomposition, single replacement, and double replacement. In this experiment, we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction, a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction, AB break down into A and B. In decomposition, energy is being absorbed which mean it is an endothermic reaction. Materials:
NaClO3 (sodium chlorate)
MnO2 (manganese dioxide)
Test tube clamp
1. Put water in the pneumatic trough
2. Attach the test tube clamp to the ring stand.
3. Put NaClO3 and MnO2 in the test tube and cover it with the stopper, mix the two compounds so that they are spread relatively evenly throughout the mixture. Put the test tube in the clamp, cover it with the stopper, and connect the hose to the stopper. 4. Fill the glass jar with water and put a glass covering over it. Hold the glass securely on top of the jar, flip it upside down, place it in the pneumatic trough, and remove the glass covering. If too much water is released, repeat this step. Carefully slip the other end of the hose into the jar without letting too much water out. 5. Light the Bunsen burner and place it under the test tube, move the tube around to make sure it is evenly heated and you get a faster reaction. 6. Once all the water is displaced, turn off the Bunsen burner, remove the hose, slide the glass covering back under the jar, and remove the jar from the water. 7. Light the Bunsen burner again and use the tongs...
