    Introduction: The purpose of the first experiment was to practice obtaining accurate and precise results by doing combustion analysis to find the amount of carbon dioxide and water released and the amount of fuel consumed. To identify the amount of carbon dioxide‚ water and burner consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released. Mass of carbon dioxide = m2 - m1 Equation 1 was used as an experimental procedure created to help find out
