How large of a percentage of carbon dioxide in the air does it take to cause a person stress?
The levels of Carbon Dioxide and impacts are: * At continuous 1% concentration of carbon dioxide CO2 (10,000 ppm) some individuals may feel sleepy * At 2% (20,000 ppm) most people are aware of its presence * At + 2%, carbon dioxide causes a feeling of heaviness in the chest awith more frequent and deeper breathing. * At 3% CO2 breathing rate doubles from normal * At 5% CO2 breathing rate is four times normal * At +5% CO2 is directly toxic. ] Symptoms of high or prolonged exposure to carbon dioxide include: * headache * increased heart rate * visual and hearing problems * dizziness and/or fatigue * rapid breathing At very high levels unconsciousness or death can occur within minutes of exposure.
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?
When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid. Lactic acid produced by anaerobic exercise also lowers pH. The drop in the blood's pH stimulates chemoreceptors in the carotid and aortic bodies in the blood system to send nerve impulses to the respiration centre in the medulla oblongata and pons in the brain. These, in turn send nerve impulses through the phrenic and thoracic nerves to the diaphragm and the intercostal muscles, increasing the rate of breathing. Even a slight difference in the bloods normal pH, 7.4, could cause death, so this is an important process.
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?
Carbon dioxide is an inorganic gas. CO2 is the chemical formula of carbon dioxide.
Will increase plant growth carbon dioxide levels above normal below normal water levels depleted soil nutrients decreased light intensity?
Increased carbon dioxide levels can enhance plant growth, as CO2 is a crucial component of photosynthesis. However, this benefit can be undermined by below-normal water levels, depleted soil nutrients, and decreased light intensity, all of which can hinder plant health and growth. Adequate water, nutrients, and light are essential for maximizing the positive effects of elevated CO2 on plants. Therefore, while increased CO2 can promote growth, it must be accompanied by optimal growing conditions for the best results.

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?
Because sedimentary rocks are formed from tiny animals which have died and fallen to the sea bed millions of years ago. Due to more substances falling onto the sea bed above the animals, they are pressurized underground. Due to the heat of Earth's core, the animals are burnt under the ground, turning into fossil fuels.These animals contain carbon dioxide, and reduce the levels from the atmosphere by dying and travelling underground. This is how sedimentary rocks are a reason for reduced levels of carbon dioxide in the modern atmosphere.Other reasons are that the carbon dioxide dissolved into oceans which were formed millions of years ago. Also, the formation of plants reduced the carbon dioxide levels due to photosynthesis, as they intake it and do not replace it, as they produce oxygen and glucose as a result of photosynthesis.
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.
