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).
Answer: 1. No 2.a. Nothing will happen to figure 1 as both the sides have 30 N. 2.b. The force with 30 N will push 10 N because 10 N is less force than 30 N.
Atomic Number (Z) = Mass Number (A) - Number of Neutrons An atom has 5 protons, 5 electrons and 6 neutrons The atomic number = number of protons = number of electrons = 5 The mass number = 5 protons + 6 neutrons = 11
