Science Component

The balanced equation for ethanol and oxygen. C2H5OH+3O2->2CO2+3H2O We chose a 43 degree angle because when we did preliminary research on optimal angles to fire a cannon, some sources said 40 degrees, some said 45 degrees, so we settled in the middle at 43. The gas law that is used in this experiment is Gay-Lussac's law. Gay-Lussac's law states that pressure and temperature are directly proportional. Pressure One times Temperature One equals Pressure Two times Temperature Two. Whatever unit is missing you solve for by isolating it.

    My group chose the same thing for our cannon. What does the last sentence have to do with the rest of it though?

    I think you can elaborate just a tiny bit more. Great job!
