How many grams of carbon should be burned in an excess of oxygen at STP to obtain 2.21 L of carbon dioxide?

At STP 2.21 L CO2 is 0.0987 moles of CO2 since 1 mole = 22.4L. One mole CO2 contains 1 mole of C so there are 0.0897 moles of C. Grams of C = 0.0987mole x 12g/mole = 1.18 grams.

Can plants obtain carbon dioxide from soil?
No they can't. They can only obtain carbon dioxide from the leaves through the gas exchange at the stoma (singular: stomata). However, plants can get water, ions, and mineral salts from the soil.
What is the processof metals removing oxygen from the metal oxide?
We can use carbon, because carbon wants to be carbon dioxide. Like tin oxide, SnO2. By adding carbon, at high temperatures, the carbon will pull out oxygen to form carbon dioxide, which is stable. The left over result is pure tin, along with other impurities and carbon dioxide gas, which is extracted from the tin.
Which process do plants obtain carbon from the atmosphere?
Cellular respiration
Where does the hydrogen in glucose ultimately come from?
All elements were created in the big bang. All the protons and neutrons and electrons joined to form many different stable compounds. Carbon, hydrogen and oxygen are some of the most abundant of elements, but like to join onto other elements as well. This means it is very hard to obtain pure hydrogen.
How many molecules of ethanol can be obtained from one molecule of sugar?
From one molecule of glucose (sugar) you can obtain two molecules of ethanol. Glucose's chemical composition is C6H12O6 Carbon dioxide (Co2) is lost in the fermentation process so we are left with 2C2H5OH or two ethanol molecules! Hope it helps!
How do plants obtain carbon?
they obtain carbon by humans and organisms, etc.
What chemical changes does coal go through?
Coal is burned to obtain heat; the chemical products of the combustion are carbon dioxide, water and ash.
Where do submerged plants obtain their supply of carbon dioxide?
The submerged plants obtain their supply of carbon dioxide from our penis or vagina.
What does animals take in and release into the atmosphere?
Animals breath in air to obtain oxygen from it and expel air again with excess carbon dioxide in it.
What does the plant obtain from the environment?
carbon dioxide
What produces the carbon dioxide that plants need?
Plants obtain the carbon dioxide they need for photosynthesis from the atmosphere.
How plants obtain carbon dioxide?
Through the air
Conclusion for carbon dioxide is necessary for photosynthesis?
The conclusion that carbon dioxide is necessary for photosynthesis is correct. Carbon dioxide and sunlight will be required so that plants can obtain energy.
Inorganic compound that is obtain by plants?
Carbon Dioxide or CO2.
Where do red blood cells obtain carbon dioxide?
from the lungs
Where does the plant obtain carbon dioxide and water?
the roots of the plant absorb the water from the soil. the stomata in the leaves absorb carbon dioxide
Where do plants get the carbon needed for carbohydrate production?
They obtain it from carbon dioxide in the air through photosynthesis.
