C1 Air Quality 4.0 / 5 based on 5 ratings ? ChemistryThe pollutants of combustionGCSEOCR Created by: Chris JenkinsCreated on: 24-04-13 16:54 How thick is the atmosphere? 15km. 1 of 17 Which 2 gases make up 99% of the atmosphere, and how are they split? Oxygen (21%) and Nitrogen (78%). 2 of 17 What are the 5 main gases in the atmosphere? Argon, Nitrogen, Carbon Dioxide, Water Vapour and Oxygen. 3 of 17 Name 3 things that help scientists know about the Early Earth? Air bubbles in ice, fossils and rocks. 4 of 17 Hw does Sulphur Dioxide affect the world? It reacts with Oxygen and Water to make acid rain. 5 of 17 Which gas changes the amount of Oxygen in the blood? Carbon Monoxide. 6 of 17 Which gas creates global warming? Carbon Dioxide. 7 of 17 Why is Nitrogen Monoxide bad? It reacts in the atmosphere to make Nitrogen Dioxide. 8 of 17 What does Nitrogen Dioxide cause? Acid rain and asthma. 9 of 17 What are the dangers of particulates? It can make asthma and lung infections worse. It also makes buildings dirty. 10 of 17 Name the 7 gases released from cars ad other vehicles? CO2, SO2, NO2, NO, CO, H2O and Particulates. 11 of 17 What influences air quality? Sources (vehicles and power stations) and Weather (wind can transfer pollutants). 12 of 17 How can you tell if there is a Real Difference? The ranges do not overlap. 13 of 17 Name a hydrocarbon? CH4 - Methane. 14 of 17 What is complete combustion? When all the combustion products are completely oxidised. All Hydrogen becomes water, and all carbon becomes Carbon Dioxide. 15 of 17 What is incomplete combustion and when does it occur? It occurs when there is limited Oxygen. Carbon becomes Carbon monoxide and Carbon instead of Carbon Dioxide. 16 of 17 What are the 2 equations for complete and incomplete combustion? ( Complete) Carbon + Oxygen = Water + Carbon Dioxide. (Incomplete) Carbon + Water = Carbon Monoxide + Water + Carbon. 17 of 17
