The canary‚ normally a very songful bird‚ would stop singing and eventually die in the presence of these gases‚ signaling the miners to exit the mine quickly. Before the development of electronic household carbon monoxide detectors in the 1980s and 90s‚ carbon monoxide presence was detected with a chemically infused paper that turned brown when exposed to the gas.

The second reaction involved magnesium ribbon. Two slabs of dry

Vehicles on the roads contribute to air pollution in major way. Most of the vehicle plying on road are fuelled by petrol and diesel emitting pollutants like Ozone gas‚ Nitrogen Oxides (NO)‚ particulate matter‚ soot smog‚ carbon monoxide (CO)‚ sulphur dioxide (SO2) etc These emissions not only pollute the environment‚ but also pose variety of health risks for people. Pollution is the main reason behind skin cancers‚ asthma‚ bronchitis‚ and other respiratory disorders. Even newborn children can

Sometimes‚ factory had leaked and outflow a large amounts of harmful gas as photochemical smog in the production process. For example: carbon monoxide will make us feel headache and fatigue and it also will cause severe hypoxia symptoms that gas poisoning. All of the harmful chemicals has already inhaled by us would lead us coughing‚ sneezing and breathing difficulties. This situation also will

Pros and Cons of using oil I want to talk about advantages and disadvantages of using oil in our world‚ people can use it for different reasons. We use oil for cars‚ airplanes etc. In some countries it is very expensive but in other countries it is much more cheaper because today its harder to find thats why its more expensive and may not be much left. Oil is very useful. For example‚ we can use it as an ingredient for our meal but also it used to accelarate the cars and how we also know doctors

Biofuels. Name: Institution: Course: Tutor: Date: A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass‚ solid biomass‚ liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye‚ D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products
