1213+Hydrogen+Pop

Chemistry students tested the sound generated by the combustion of a hydrogen / air mixture in a test tube. Their results are shared below.

Students will write a short essay which summarizes the results of the experiment and explains those results using the ratios found in a chemical reaction. The essay only needs two paragraphs. Remember, air contains around 20% oxygen, so 30 mL of air contains only 6 mL of oxygen. When your essay is complete, hand it to your teacher.
 * 1) Summarize the results by describing the procedure and observations. These descriptions do not have to be very details and should not be a numbered list of steps.
 * 2) Using the ratio of hydrogen to oxygen in the reaction, explain the results. Include a short explanation for results that did not fit the trend. In other words, describe some of the problems with this lab procedure.

Each group has constructed a table showing the results of several trials. The format of each table is identical.
 * Trial || 25% H2 || 50% H2 || 75% H2 || 100% H2 ||
 * 1 ||  ||   ||   ||   ||
 * 2 ||  ||   ||   ||   ||
 * 3 ||  ||   ||   ||   ||
 * 4 ||  ||   ||   ||   ||

Each group's results are separated from the other groups by a horizontal rule.
