Pollution 05/03/2021 Some examples of pollution… Carbon dioxide, water vapour, carbon monoxide are caused by the burning of _____. Carbon monoxide is a ____ gas and is not easily detected due to being ____. Sulfur dioxide and nitrogen dioxide cause ____ which damages trees and buildings and _____ problems in humans. Particulates (unburned _______) can make buildings dirty, worsen breathing difficulties and cause global ______. Words – hydrocarbons, dimming, fossil fuels, odourless, acid rain, respiratory, toxic
Pollution 05/03/2021 Consequences of pollution… Carbon dioxide causes the _____ leading to _____. Carbon monoxide causes ____ and at higher concentrations can cause ____. Sulfur dioxide also causes _________ in animals including humans but is also responsible for ________. This can kill ______ and ______, acidifies ____ as well as damaging ____ and _______ constructions. Nitrogen dioxide cause ____ when it reacts with sunlight. This damages peoples _______ causing breathing difficulties. Particulates cause breathing difficulties, lung ____, and cause global _____.
Match each pollutant to its chemical formulae and how it is produced. Carbon monoxide Sulfur dioxide Nitrogen oxides Carbon / soot 6 Production of solid particles from the incomplete combustion of fuels containing carbon Oxidation of nitrogen in the air inside the engine of a car for example Production of a gas from the incomplete combustion of fuels containing carbon Combustion of a fossil fuel which contains sulfur impurities SO₂ CO C NOₓ
Carbon monoxide SO₂ Sulfur dioxide Oxidation of atmospheric nitrogen inside the engine of a car for example CO Nitrogen oxides Production of a gas from the incomplete combustion of fuels containing carbon C Carbon / soot 7 Production of solid particles from the incomplete combustion of fuels containing carbon Combustion of a fossil fuel which contains sulfur impurities NOₓ
Combustion of Fuels H Lots of oxygen: H H C Some oxygen: H O H Methane H O + H H O H O C H Methane + O Oxygen O C O H O Carbon dioxide O C + O Oxygen 05/03/2021 Carbon monoxide + O H H Water H O H O H H Water
Incomplete Combustion 05/03/2021 As well as producing carbon monoxide, incomplete combustion can also produce soot: Little oxygen: H H H O C H Methane + O Oxygen C Carbon “Soot” + H O Water H H
Other products of burning fuels 05/03/2021 Sulphur dioxide: S O O Sulphur Nitrogen monoxide: N + Oxygen O N Sulphur dioxide N O N Nitrogen dioxide: S O O N + Oxygen Nitrogen monoxide O + O Oxygen O Nitrogen monoxide O O Nitrogen dioxide
Complete the worksheet Complete EITHER the normal questions or the challenge questions (Grade 6+) on the worksheet You can type in your answers on teams or write/print them out. If you type them please change the font colour to make it easier for me to spot your answers. If you write them out please upload a photo to Teams (see video in email to show you how) Submit your work on Teams
Task 2 05/03/2021 READ THROUGH the information sheet and then try to complete the wordsearch. You can either do this on word or just upload a photo of the finished version
