Above normal levels of carbon dioxide refer to an increase in the concentration of this greenhouse gas in the atmosphere beyond what is considered typical. This increase is typically due to human activities such as burning fossil fuels, deforestation, and industrial processes, leading to global warming and climate change.
The exact percentage varies between individuals, but levels above 800-1000 parts per million (ppm) of carbon dioxide in the air can start to cause discomfort and stress for some people. Long-term exposure to high levels of carbon dioxide can lead to more serious health effects.
Carbon Dioxide is a compound formed by a Carbon and Oxygen. Only an element can be classified as a metal, non-metal or a metalloid. Compounds cannot be classified in these categories. Carbon and oxygen both are non-metals.
D ; All of them. NB When we breath out )Exhale/Respire) we breath outy carbon dioxide. B ; Volcanoes releaser carbon dioxide, together with other gases e,g, steam, sulphur dioxide, hydrogen sulphide , amongst other gases and liquid rocks. C ; We burn fossil fuels(petrol/gas/diesel) in cars and power stations. They also release CO2.
Carbon monoxide can burn because it is a reducing agent that can donate electrons in a chemical reaction, supporting combustion. In contrast, carbon dioxide is already in its most stable form with a full complement of electrons, so it does not have the necessary properties to support combustion and burn.
Exposure to carbon dioxide triggers chemoreceptors in the body that detect changes in blood pH. High levels of carbon dioxide lead to a decrease in blood pH, which signals the brain to increase the rate of breathing in order to remove excess carbon dioxide and restore pH balance.
respirations increase in rate and depth
When the level of arterial carbon dioxide rises above normal, it can lead to respiratory acidosis, which is a condition where the blood becomes too acidic due to excess carbon dioxide. This can cause symptoms such as confusion, headaches, and breathing difficulties. It can also lead to complications if not treated promptly.
During the day, trees in a forest undergo photosynthesis, where they take in carbon dioxide to produce oxygen and organic compounds. This process decreases the concentration of carbon dioxide in the air above the forest.
The substance of carbon dioxide is a molecule composed of one carbon atom and two oxygen atoms, represented by the chemical formula CO2.
The exact percentage varies between individuals, but levels above 800-1000 parts per million (ppm) of carbon dioxide in the air can start to cause discomfort and stress for some people. Long-term exposure to high levels of carbon dioxide can lead to more serious health effects.
During the past 500,000 years, levels of carbon dioxide in the atmosphere never rose above 300 ppm (parts per million) or 0.03%. Since the Industrial Revolution, 200 years ago, when we began burning coal, levels have risen to their present (2013) levels of 400 ppm (parts per million) or 0.04%.
Actually none of the options given above are true for carbon dioxide. Though carbon and oxygen are both non-metals, carbon dioxide is considered as a compound.
The formation of sedimentary rocks reduces carbon dioxide levels by trapping carbon through weathering and erosion processes that sequester carbon in rock formations over long periods of time. This removes carbon from the atmosphere and helps mitigate the greenhouse effect, contributing to the regulation of the Earth's climate.

No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.
Carbon dioxide, water, and ozone are all known greenhouse gases.
