Since excess carbon dioxide, if present in water, easily escapes to the atmosphere, tests for carbon dioxide should be performed immediately after collection of water sample (especially for ground water samples which usually contain high carbon dioxide).

Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface

1.9 moles are in the sample of CO2. 1 mole of CO2 contains 1 mole of C and 2 moles of O.

It completely depends on where the sample is taken. E.g: if it was taken is the city it would have more carbon dioxide than on a farm.

oxygen in a sample of expired air converts any alcohol present into acetic acid and then to water and carbon dioxide. A fuel cell converts the chemical energy released when oxidation occurs into a detectable electrical voltage. The higher the voltage, the more alcohol is present in the sample.

Pure carbon monoxide is a compound, containing equal numbers of carbon and oxygen atoms in any sample of the compound.

The gram molecular mass of carbon dioxide is 44.01. Therefore, the number of atoms in 22g of carbon dioxide is (22/44)(Avogadro's Number) or 3.0 X 1023, to the justified number of significant digits.

The molecular mass of carbon dioxide is 12.0 + 2(16.0) = 44.0 Amount of carbon dioxide in a 44g pure sample = 44/44.0 = 1mol

if it is a pure sample of C, nothing is left, burning forms carbon dioxide gas which mixes with the air and is gone.

Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.

The mass of any substance depends on the size of your sample. The mole mass of carbon dioxide is 44g.

Chalk should dissolve producing effervescence (due to the formation of carbon dioxide). Chalk is calcium carbonate and dissolves is nitric acid forming calcium nitrate and carbon dioxide.

A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure. The pressure would be if the gas exerted if the volume was decreased to 2.00 liters would be 219kpa.

Type your answer here... we can make the solution of copper chloride for orsat apparatus.

See the Related Question (link to the left of this answer)."How many moles of carbon dioxide are there in a 50.0 dm3 sample of the gas at a pressure of 100.0 kPa and a temperature of 50 degrees celsius?" 1.86 moles

Carbon-14 dating is the measurement of an object's age by comparing the amount of carbon-14 to the amount of carbon-12 and carbon-13 present in the sample.

Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.

10,500 years old The carbon-14 in a wooden sample shows a ratio of 0.0093 between the carbon-14 in the wood and present-day samples. The half-life of carbon-14 is 5,730 years. How old is the wood? 38,700 years old

in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4

Argon was found in the gaseous state. A sample of clean air was taken. Then oxygen, carbon dioxide, water, and nitrogen were removed. One unknown gas was still in the sample. This was later determined to be Argon.
