Combustion of fuels and atmospheric pollutants are key contributors to... Show more
The combustion of alkanes, which are common components in fuels like petrol, can occur in two ways: complete and incomplete combustion. Complete combustion happens when there is plenty of oxygen available, resulting in the production of carbon dioxide and water vapor. These are greenhouse gases that contribute to global warming. On the other hand, incomplete combustion of alkanes and its impacts on health occur when there is a lack of oxygen, which is more likely to happen when burning fuels with longer carbon chains.
Vocabulary: Alkanes are a group of hydrocarbon compounds with the general formula CnH.
Incomplete combustion produces carbon monoxide, which is a toxic, colorless, and odorless gas. This gas can bind to hemoglobin in red blood cells, taking the place of oxygen and potentially leading to suffocation. Additionally, if carbon particles are produced instead of carbon monoxide, they can contribute to global warming by reflecting sunlight back into space and hindering photosynthesis in plants.
Highlight: Carbon monoxide, a product of incomplete combustion, is particularly dangerous due to its ability to bind with hemoglobin and displace oxygen in the blood.
The formation of sulfur dioxide and nitrogen oxides in air pollution is a significant concern. Sulfur dioxide is formed when sulfur impurities in fuels react with oxygen at very high temperatures. This acidic gas can cause damage to buildings, contribute to acid rain that harms trees and wildlife, and cause breathing problems in humans. Sulfur dioxide can be neutralized, but a more effective prevention method is to remove sulfur from fuels before burning.
Example: Acid rain, caused by sulfur dioxide and nitrogen oxides, can damage buildings, trees, and harm wildlife.
Nitrogen oxides are formed when nitrogen and oxygen in the air react at high temperatures during combustion processes. There are various types of nitrogen oxides, such as NO2, N2O2, and NO3, all of which are toxic. Like sulfur dioxide, nitrogen oxides can contribute to the formation of acid rain when they dissolve in rainwater.
Vocabulary: NOx is a collective term for various nitrogen oxide compounds formed during combustion.
Highlight: Both sulfur dioxide and nitrogen oxides contribute to acid rain formation, which has wide-ranging environmental impacts.
Atmospheric pollutants are substances that contaminate our air, making it harmful or damaging for human health and the environment. The main sources of these pollutants are the combustion of fuels in factories, power stations, trucks, and cars. The pollutants produced include carbon dioxide, water vapor, sulfur dioxide, carbon monoxide, nitrogen oxides, carbon particles, and unburnt hydrocarbons. It's important to note that some of these substances are already present in the atmosphere but become pollutants when their concentration becomes too high.
Definition: Atmospheric pollutants are substances that contaminate the air, making it harmful for human health and the environment.
Example: Common sources of atmospheric pollutants include factories, power stations, and vehicles.
Highlight: Even naturally occurring substances can become pollutants when their concentration in the atmosphere becomes too high.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
