combination will result in a unique ratio‚ thus allowing us to compare unknown samples and discover their identity.

varying temperatures are targeted towards being at 10ºC‚ 20ºC‚ 30ºC‚ 40ºC‚ and 50ºC. It is highly improbable that each trial for each of the 5 different temperatures will be the exact temperature that was targeted‚ so it’s just important that you end up having a temperature fairly close to the targeted temperatures so that the rates of reactions that you do receive are as correct as possible. The rates of reaction will be obtained using an apparatus that will guide the carbon dioxide gas being produced
