How many moles of carbon dioxide are formed from 14 moles of methane?
When methane undergoes complete combustion, the equation for the reaction is CH4 + 2 O2 -> CO2 + 2 H2O. This shows that the number of moles of carbon dioxide formed are the same as the number of moles of methane reacted, so that 14 moles of carbon dioxide will be formed from 14 moles of methane.
What mass of carbon dioxide can be produced from 25.0g of C6H14 and excess oxygen?
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
How many moles of carbon are needed to react with 580 g of hematite?
Which carbon are u talking about? Carbon in coke is first oxidised to form carbon dioxide - C(s) + O2(g) -> CO2(g). Limestone is decomposed by heat to form calcium oxide and carbon dioxide. CaCO3 -> CaO(s) + CO2(g). The carbon dioxide produced in the two reactions are reduced by carbon in coke to form carbon monoxide. CO2(g) + C(s) -> 2CO(g). The carbon monoxide then reacts with iron (III) oxide in haematite to form iron and carbon dioxide. Fe2O3(s) + 3CO(g) -> 2Fe(l) + 3CO2(g). If ur referring to this last reaction above, 520grams of iron (III) oxide react with 210grams of carbon dioxide. Mol. of Fe203 reacted -> (520/104) = 5mol. Mol of carbon dioxide reacted -> 5 X 3 = 15. Mass of carbon dioxide reacted -> 15 X 14 = 210g
Why is carbon dioxide heavier than nitrogen?
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
How many moles is 14 g of CO gas?
To determine the number of moles in 14 g of CO gas, you need to first calculate the molar mass of carbon monoxide (CO), which is 28.01 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 14 g of CO gas is equal to 0.499 moles.
0.085g of amonia is to how many moles?
The calculation is: Moles = Mass / Atomic Mass Moles = 0.085 / 17 Moles = 0.005 Atomic mass is 17 because ammonia is NH3, with N = 14, and H = 1. 14 + 1 + 1 + 1 = 17.
How many moles are in 14g of silicon?
To find the number of moles in 14 grams of silicon, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of silicon is approximately 28.09 g/mol. Therefore, the number of moles in 14 grams of silicon is 14 g / 28.09 g/mol, which is approximately 0.497 moles.
How many carbon atoms react with 14 molecules of oxygen to form 14 molecules of carbon dioxide with the equation C O2CO2?
With the chemical equation given, each molecule of carbon dioxide contains 1 carbon atom. Therefore, 14 molecules of carbon dioxide will require 14 carbon atoms to react with the 14 molecules of oxygen.
What are three isotopes and isobars of carbon?
isotopes of carbon are atomic no. 6 mass 12 , atomic no.6 mass 13 , atomic no. 6 mass 14
What is the atomic number of carbon 14?
Carbon is a non metal element. Atomic mass number of it is 12.
How many moles of C are in 2.30 mol naproxen C14H14O3?
Naproxen (C14H14O3) contains 14 carbon (C) atoms per molecule. To find the number of moles of carbon in 2.30 moles of naproxen, you multiply the number of moles of naproxen by the number of carbon atoms per molecule: 2.30 mol naproxen × 14 mol C/mol naproxen = 32.2 mol C. Thus, there are 32.2 moles of carbon in 2.30 moles of naproxen.
How is c14 produced?
Carbon-14 (C-14) is produced in the atmosphere when cosmic rays react with nitrogen gas (N-14), creating radioactive carbon dioxide. This radioactive carbon dioxide then mixes with regular carbon dioxide in the atmosphere, leading to the incorporation of C-14 into living organisms through photosynthesis.
