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.

How large of a percentage of carbon dioxide in the air does it take to cause a person stress?
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.
Is carbon-dioxide a non-metal?
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.
Carbon dioxide is produced by A Respiration B Volcanic Eruptions C Burning Fossil Fuels D All of the Above?
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.
Why does carbon monoxide burn and carbon dioxide does not?
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.
Why does exposure to carbon dioxide increase the rate of breathing?
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.
When the level of arterial carbon dioxide rise above normal?
respirations increase in rate and depth
What happens When the level of arterial carbon dioxide rises above normal?
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.
Why the concentration of carbon dioxide in the air above a forest decreases during the day?
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.
What is the name of the substance of carbon dioxide?
The substance of carbon dioxide is a molecule composed of one carbon atom and two oxygen atoms, represented by the chemical formula CO2.
How large of a percentage of carbon dioxide in the air does it take to cause a person stress?
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.
What are the levels of carbon dioxide from past to present?
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%.
Is carbon dioxide metal nonmetal or metalloid?
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.
How does the formation of sedimentary rocks reduce carbon dioxide levels?
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.
Carbon is found in?
fossil fuels the soil and the ocean fruit and vegetables carbon dioxide all of the above
Is carbon dioxide lighter than helium?
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.
How does the spiny lobster obtain oxygen and give off carbon dioxide?
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.
Which is a greenhouse gas A Carbon Dioxide B Water C Ozone D All of the Above?
Carbon dioxide, water, and ozone are all known greenhouse gases.
