Enthalpy of combustion glycerol
WebHeat this mixture to 55- 60C and stir with a stir bar for 45 minutes. 6. Pour mixture into a separatory funnel and let sit for about 10-15 minutes. Make sure the stopcock is closed before adding your mixture to the funnel. The separatory funnel will allow for the separation of the glycerol (d = 1.26 g/mL) from the biodiesel (d ≈ 0.85 g/mL). 7. WebShown above is the combustion reaction for glycerol, C,H,O, (molar mass = 92 g mol-'). A student ignites 5.000 grams of glycerol and uses the energy to heat a sample of 1.000 x 10°g of water in a metal, insulated container. The student measures the change in temperature of the water to be 20.06 °C. Determine
