I mostly need help with number 4, but any other information is appreciated
------------------
Here are the steps to the experiment:
1. Light the candle with a match (or a lighter).The fuel that supports burning of the wick is paraffin.CAUTION: Hold the test tube opening a centimeter above the flame to capture all the gases. Hold the test tube at the opposite end away from the flame, so that you do not burn your fingers.2. Hold the small glass test tube in an inverted position (with the opening facing downward) over the candle wick for 30 seconds. This collects the gases released by the burning candle. After 30 seconds, move the inverted test tube away from the flame. Keep the test tube inverted.3. Record your observations of the gasses collected in the small test tube in DataTable 1. Photograph your observations.4. Locate the small cup containing the vinegar and baking soda from Activity 4.
5. Slowly add another 50 mL of white vinegar to the small cup.6. Carefully pour the gasses that are generated over the candle flame.7. Record your observations in Data Table 1.8. Place the glass test tube containing the limewater in the cardboard test-tube rack.9. Tilt the large test tube horizontally, so that vinegar pours out of the polystyrene test tube into the larger test tube, and reacts with the baking soda.10. As soon as the reaction starts, stop adding vinegar to the reaction and quickly place the free end of the plastic tubing into the limewater solution in the small test tube.continued on next page
Activity 5: Combustion Reaction Follow-Up Questions (2.5 points) Answer the questions below when Activity 5 is complete. 1. What evidence was there indicating a reaction took place in Activity 5? Rising water vapors 2. The combustion reaction produces TWO gases. One of the product gases condenses to a liquid when it comes in contact with the room temperature test tube held above the flame. Determine the identity of this gas. Click or tap here to enter text. 3. The second of the product gases is the same as the gas poured over the flame from the vinegar + baking soda mixture. Determine the identity of this gas. Click or tap here to enter text. 4. One of the typical components of candle wax has the formula C31H64. Write the balanced chemical equation for the reaction, including phase labels, in Activity 5. Click or tap here to enter text.
