Passage Students Were Asked to Bring Items from Home to Serve

Passage
Students were asked to bring items from home to serve as examples for different types of reactions.  The instructor provided additional reactants, solvents, heat, or a catalyst to demonstrate reactions with the household items.The students brought aluminum foil, table salt, sugar, baking soda, vinegar, toilet bowl cleaner, hydrogen peroxide, and antacid tablets.Experiment 1Reactions were performed using the household items.  The reaction conditions and student observations are recorded in Table 1.Table 1  Reaction Conditions and Visual Observations
Experiment 2The reactions that were observed to produce gas bubbles in Experiment 1 were repeated, and samples of the gases produced were collected.  Each gas sample was tested by holding a burning (glowing) wooden splint within the reaction vessel to determine if the reaction evolved O₂, H₂, or CO₂.  A glowing splint placed in O₂ will burn more brightly, one placed in H₂ will ignite the gas, and one placed in CO₂ will be extinguished.  The results of the gas tests are recorded in Table 2.Table 2  Glowing Splint Gas Test Observations

-When sugar is burned completely, the following unbalanced combustion reaction takes place:C₁₂H₂₂O₁₁ + O₂(g) → CO₂(g) + H₂O(g) + heatIf the reaction is balanced, it has a ratio of:

A) 1 CO₂(g) to 1 H₂O(g) .
B) 3 CO₂(g) to 2 H₂O(g) .
C) 6 CO₂(g) to 5 H₂O(g) .
D) 12 CO₂(g) to 11 H₂O(g) .
