Please help with my chemistry homework! : Fuel burns in a car engine. Describe how oxides of nitrogen are produced in a car engi
ne. I stated: -very high temperatures in the car engine create a reaction of oxygen and nitrogen. But I'm unsure if this is correct and would award me the full 2 marks?
When fuels are burned in vehicle engines, high temperatures are produced. At this high temperature, nitrogen and oxygen from the air combine with each other to produce nitrogen monoxide (NO). When this nitrogen monoxide is released in the air from vehicle exhaust systems, it combines with oxygen present in the air to form nitrogen dioxide (NO2).
Using the length given '12 m', because the shape of the object is a square all sides are congruent. Basically 12+12+12+12=48 or 12 x 4= 48 The answer is 48 m
