WebHeat: In order to start a fire, the fuel and oxygen reacting with each other must exceed a threshold called the flash point. The flash point is the temperature at which the chemical reaction can combust, producing a flame. Different chemicals have different flash points, some relatively high, and some incredibly low. WebExpress your answer as a chemical equation including phases. 4NO2 (g)+O2 (g)+2H2O (l)→4HNO3 (aq) Nitric acid in acid rain forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid. Write a balanced chemical equation for this reaction. Express your answer as a chemical equation.
WebApr 23, 2012 · Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, … Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize (if this process happens in inert atmosphere without oxidizer, it is called pyrolysis). In this state they can then readily react with oxygen in the air, which gives off enough hea…
WebNo, it is a physical reaction because you still have water. However, the flame itself is a chemical reaction because the fuel no longer exists once burned. A chemical reaction occurs when you no longer have the same substance or substances, but have some new substance or substances.
