Environmental issues caused by CO2
- The amount of greenhouse gases increases as carbon dioxide levels rise, trapping more heat. Due to the ice caps melting and the rising ocean levels brought on by this stored heat, flooding results.
- CO2 emissions from all across the world contaminate our clean air and leave behind an impenetrable layer. This blanket, in a sense, traps heat inside the soil, causing it to warm up. The greenhouse effect is another name for this phenomenon.
- Carbon dioxide is released into the environment by the burning of fossil fuels, the release of chemicals into the atmosphere, the reduction of forest cover, and the acceleration of industrial, agricultural, and horticultural activity, both of which change the balance of the climate system.
Applications of O2:
- It is employed in mining as well as the making and fabrication of glass and stone items.
- In situations of high pressure, specialised oxygen chambers are utilised to raise the partial pressure of oxygen surrounding the patient.
- The main uses of oxygen are in the melting, refinement, and production of steel and other metals.
The number of moles of carbon dioxide which contain 8 g of oxygen is: (a) 0.5 mol (b) 0.20 mol (c) 0.40 mol (d) 0.25 mol
The number of moles of carbon dioxide which contain 8 g of oxygen is 0.25 mol. Oxygen is mainly used in the mining and fabrication of stone and glass items. It is a major reason for refinement, melting, and steel production.
