What is the formula mass for C2H6O?
Methane is an elementary organic compound having the molecular formula of CH4. Methane is composed of carbon (C) and hydrogen (H) atoms. The molecular weight of CH4 is 16. 01 grams per mole.
When a 1.25-gram sample of limestone was dissolved in acid 0.44 gram of CO2 was generated if the rock contained no carbonate other than CaCO3 what was the percent of CaCO3 by mass in the limestone?
CaCO3 +2HCl ------------> CaCl2 + CO2 + H2O number of moles of CO2 in .44 grams = .44/ 44 = .01 From equation it is clear that 1 mole of CO2 is produced from CaCO3 = 1 mole .01 mole of CO2 is formed from CaCO3 = .01 mole Weight of .01 mole of CaCO3 is = .01mole *100 g/mole = 1 gram weight % of CaCO3 is = 1*100/ 1.25 = 80 % w/w I've post my answer, so why don't you show that answer here with the question. It's fare. I must be informed about my answer weather it is right or wrong. Please inform me at amitmahalwar@yahoo.com
What percent of the atmosphere is co2?
In 2014 carbon dioxide levels are around 400 ppm (parts per million) or 0.04%.
What is carbon's atomic mass?
Carbon's atomic mass is ~12.0107. All of those decimals at the end tell us that there is more than one isotope of carbon. If you round the number, you will find the most common isotope of carbon. (Carbon12)IUPAC recommend in this case the expression atomic weight, not atomic mass.The atomic weight of carbon (IUPAC Table, 2009) is [12,0096; 12,0116]. This mean that the atomic weight is variable between the above mentioned limits, depending on the type of the sample.
Molecule of water?
A molecule is when one or more atoms are chemically combined. This is generally done with more than one element. The water molecue has two atoms of hydrogen to every one of water. This is indicated by the little 2 in H2O.

76.55% nitrogen 20.54% Oxygen 1.96% water vapor .91% argon .03% Carbon dioxide .01% Misc. gases Those are six, I couldn't find the other one.... :D
Is coal a direct form of carbon dioxide?
NoCoal is generally made up of long chain and cyclic carbon-hydrogen compounds called hydrocarbons. In some places it may also contain significant amounts of sulfur and other contaminants.When one burns it as a fuel (oxidization), it generates a tremendous amount of heat. The hydrogen combines with oxygen to form plain water in the form of steam. The carbon combines with oxygen to form carbon dioxide.So, while the coal is a stable form of carbon that has been in the earth for thousands or millions of years, burning it produces carbon dioxide.Keep in mind that the total carbon dioxide concentration in the atmosphere is between 0.03% and 0.04%, or about 390 parts per million now. Over the last hundred years the total change has been about .01%. But, in total levels that is an increase of about a third.
What in a chemical formula tells how many atoms of each element are found in a unit of compound?
The number of atoms that one element will combine with another is the ratio. For example, water, H2O, contains two hydrogen atoms and one oxygen atom. The ratio of elements is two hydrogen atoms to one oxygen atom, 2:1. Every molecule (compound) of water will show this ratio of elements.
Eschar?
DefinitionEschar is dead tissue that sheds from healthy skin. It is caused by a burn or cauterization. An escharotic is a substance (such as acids, alkalies, carbon dioxide, or metallic salts) that causes the tissue to die and shed.
