Acid rain is rain consisting of water droplets that are acidic due to the polluted atmosphere, which we know is caused mainly through large amounts of sulphur and nitrogen released by cars and industrial processes. Wet Deposition When the acid chemicals get blown over areas that have wetweather,...
Day, the once very blue, but because of air pollution from factories, make the blue of the sky becomes cloudy; Water was very clear, but because the effluent from the factory, once the bottom stream become colorful; Forest, once very lush, but due to the deforestation of people, make on...
Two chemicals react in an endothermic reaction. What can be known about this reaction? What type of chemical reaction is combustion? What are the mechanism and chemical reaction formula of this reaction? What is the chemical equation for sodium bicarbonate?
Explain why CFCs eventually make their way into the stratosphere even though most chemicals released into the atmosphere do not. Describe the water and carbon cycle. How do they contribute to climate change? Describe how do lungs work according to Boyle's law of gases. ...
When chemicals in the air mix with rain, we have acid(酸) rain. Acid rain can bring us great harm. It destroys(破坏) forests and kills life in lakes and rivers. People are beginning to see how serious the problem is. They find it important to work with nature ...
(5) use chemicals, Such as water retention agent, anti - transpiration agent, etc.. What's frost like? Frost refers to objects or near the ground surface temperature is reduced to 0 DEG C or below, white crystal direct sublimation vapour in the air in the body; sometimes less when the...
Petrichor is not the only rain-related smell. There's another distinctive scent caused by theacidity of rain. Because of chemicals in the atmosphere, rainwater tends to be somewhat acidic, especially in urban environments. When it comes in contact with organic debris or chemicals on the ground,...
“Acid rain comes from chemicals(化学物质) in the air. The pollution comes from factories, cars and trucks.” “So, although I don’t want to, I help the pollution travel through the air!” says the wind. “And I carry it to the land!” cries the rain. ...
These chemicals are flocculating chemicals that help in water filtration. What they do is that they clump the particles together until they form a larger particle. These flocks can then be easily removed or filtered out. Some chemicals used are fluorosilicic acid, sodium silicofluoride...
