The amounts of any gas is a variable in our air. CO2, in our atmosphere has varied from 0.8 to as low as 0.027%. It is currently at 0.038% in much of the industrialized world. It still remains lower some areas, like Antarctica. We are still much lower in CO2 levels then many times in our past. The oceans are the big regulator here. They create 94% of all CO2 and absorb it back if levels get higher then the earth can support. If the planet warms, oceans absorb slightly less CO2 per day and that is why we see these variable levels. Forests are another large source of CO2. If we see fires or rotting trees they are giving off CO2. The vegetation on the floor of the forest is also giving off levels of CO2.
Oxygen is very similar. It varies in concentrations in many area and temperature zones as well. Forests, for example, will have a higher concentration of oxygen.

∙ 12y ago1. The amount of Carbon has remained level until recently because previously Carbon was in a constant cycle, thus meaning that whenever new Carbon dioxied was generated by dying plants, Carbon dioxide was removed from the atmosphere by means of Photosynthesis, this is the Carbon Cycle. But currently Carbon Dioxide levels are rising because Fossil Fuels are being used in Power Stations and Factories.

∙ 11y agoGreen plants absorb carbon dioxide from the atmosphere and use it as an ingredient for photosynthesis, while animal metabolism produces carbon dioxide which is then exhaled into the atmosphere. These two processes take place at approximately the same rate, so the overall level of carbon dioxide in the atmosphere is not changed by these things. Of course, when people burn fossil fuels, that is another matter.

∙ 11y agoCarbon dioxide levels are not stable, they are rising. Two hundred years ago they were around 280 ppm (parts per million) and had been that way for many thousands of years. They are now over 390 ppm. Scientists agree that this rise is being caused by deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).

How does the mass of nitrogen dioxide compare to the mass of products of the chemical reaction when it is split into elements?
The total mass remain constant.
When a person's diet is too low in calcium the blood levels of calcium will remain constant because the body will get calcium from?
bone
Function of lime water?
It is to test for the presence of carbon dioxide. If carbon dioxide is present,it will turn chalky however if carbon dioxide is absent,lime water will remain colourless.
Why is the amount of carbon dioxide in air almost constant?
Without getting too technical on this answer the main reason is a physics law known as the Ideal Gas Law.The law is derived from the fact, that in the ideal state of any gas a given number of its "particles" occupy the same volume, and that volume changes are inverse to pressure changes and linear to temperature changes.With the basis that gravity is the same at equal distances around the planet the pressure variations allow for all the gases of the earths atmosphere to mix equally.The currently accepted levels for gases in the earths atmosphere are as follows :N2 - 78.08%O2 - 20.95%H2O - 0 to 4%Ar - 0.93%CO2 - 0.0360%Ne - 0.0018%He - 0.0005%CH4 - 0.00017%H2 - 0.00005%N2O - 0.00003%O3 - 0.000004%
Carbon dioxide and water make what substance?
Carbonic acid, H2CO3, is probably the answer you want, but it's not the only thing. If you add carbon dioxide to fresh water (the salt in seawater seems to have a catalytic effect) most of it will remain as carbon dioxide and you'll get...carbonated water, a solution of CO2 in H2O. Both of those compounds are so stable it's hard to get them to react with anything.
Why does oxygen and carbon dioxide remain the same?
it doesn`t
What causes carbon dioxide to turn to carbon monoxide?
revalent ideas and personification it can remain difficulty
Does smoking tobacco raise blood pH levels?
The pH of human blood tends to be very stable because the dissolved carbon dioxide, which is a metabolic by-product, forms carbonic acid which acts as a pH buffer. Smoking tobacco will add more carbon dioxide (as well as carbon monoxide) to the blood, but the pH will remain the same.
How does cutting down forests affect the carbon cycle?
It affects the carbon cycle because when photosynthesis happens plant take in Carbon Dioxide and release oxygen. When the trees in the forest are cut down photosynthesis is reduced. Meaning, carbon dioxide will remain in the air that we breathe.
What happens after you burn a match?
Burning release carbon dioxide and water; a small amount of ash remain.
How does the mass of nitrogen dioxide compare to the mass of products of the chemical reaction when it is split into elements?
The total mass remain constant.
If you have raised CO2 in the body does that mean your oxygen saturations would be lower and work of breathing would increase?
Oxygen is used to metabolize carbohydrates and produces carbon dioxide. In addition an increased rate of respiration will lower carbon dioxide levels while increasing oxygen concentrations to saturation. Despite this they are two independent parameters. If someone were to be at a high altitude they could have almost no C02 in their blood, be breathing rapidly and have low oxygen levels. Similarly carbon monoxide will bind strongly to hemoglobin so that oxygen levels will go down, but since except at very low levels of oxygen, breathing will remain unchanged as CO2 levels, which drive the rate of respiration normally will be unchanged.
Gases present in Mars atmosphere is this helpful or harmful?
Excessive carbon dioxide is harmful and, therefore, humansÊcan not surviveÊon mars.ÊMars contain 95% carbon dioxide, 3% nitrogen, 1.6% argon and the remain has traces of oxygen.
