What is the ratio of oxygen to carbon dioxide in the lungs?
2/100 percent to the carbon dioxide
In the last 100 years what has added excess carbon dioxide to the atmosphere?
Power PlantsMachineryCarsThe burning of fossil fuels like coal, oil and natural gas, which releases extra carbon dioxide that has been underground for 300 million years.
How much hotter is the earth since the levels of carbon dioxide went up?
the earth is much hotter like 100%
Why have greenhouse gases increased so much in the past 100 years?
There have been a lot of upward trends in the past 100 years - population, industrialization, use of motor vehicles - each of thee contributes to GHG emissions, particularly carbon dioxide. In addition, the deforestation of many areas of the world either through logging, climate shifts or the increasing need for agricultural land has reduced the ability of the eco-system to absorb carbon dioxide. Still in the carbon dioxide sequestration area, changing farming practices have reduced the amount of carbon retained in the soil. Even more, the thawing of much of the permafrost in North America and Europe/Asia has liberated methane, a potent GHG with 21 times the impact of carbon dioxide. Then again there are new GHGs which were not even thought of 100 years ago - substances like CFCs and SF6 - which are very potent GHGs.
What state is carbon dioxide at -100 degrees Celsius?
liquid
What gasses are found in the thermosphere?
100 percent carbon dioxide
What gas has been increasing in the atmosphere for the last 100 years?
Carbon dioxide (CO2) has been increasing in the atmosphere for the last 100 years. It is primarily released through the burning of fossil fuels such as coal, oil, and gas, as well as deforestation and other land-use changes. This increase in CO2 concentrations is a major driver of climate change.
What are the end products of burning propane assuming 100-percent efficiency?
Water and Carbon dioxide. Here is the Balanced combustion eq'n. CH3CH2CH3 + 5O2 = 4H2O + 3CO2
Why is the concentration of carbon dioxide rapidly increasing in the Earths atmosphere?
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.
What is a nonexample of carbon dioxide?
The possibilities are infinite:any of the over 100 elements on the periodic table (including carbon and oxygen)any of the billions and billions of chemical compounds - other than carbon dioxidea baseballsausagesscrambled eggsa planetetc.
What mass of carbon dioxide could be made from 100 tons of calcium carbonate?
44g of carbon dioxide is made with 100g of carbon dioxide. So, if 1 tonne is 1,000,000g, you need to multiply 44 by 1,000. Which makes 44,000, which is 0.044 tonnes.
What does carbon dioxide and water form?
Carbon dioxide and carbon monoxide are created from combustion of organics. If the combustion is not 100% complete you will get carbon monoxide and carbon dioxide. if its 100% you will only get carbon dioxide. (as a side note - the energy you get from food is from a process a lot like combustion, so we are internal combustion engines producing CO2. That's why we breath it out)
