Take 2.16 g of the material and make it burn fully. It is measured that only 2.16 g of hydrated carbon dioxide and 5.28 g of carbon dioxide are produced. How much hydrogen and carbon are contained in the material ,
The amount of water is n = = 2.16g/18g * mol-1 = = 0.12mol, the hydrogen element in it is all from organic matter, and the mass of hydrogen element is 0.12 * 2 = = 0.24g;
The amount of carbon dioxide is n = = 5.28g/44g * mol-1 = = 0.12mol, in which the carbon element is all from organic matter, and the mass of carbon element is 0.12 * 12 = = 1.44g
So the mass of oxygen in 2.16G organic matter is 2.16g-0.24g-1.44g = = 0.48g
Compound A, 23 g, is completely burned in air to produce 44 g of carbon dioxide and 27 g of water, which are the only two substances
A 23 g compound A is completely burned in air to produce 44 g of carbon dioxide and 27 g of water. Only these two substances are produced. Then 23 g a contains 12 g of carbon and 3 g of hydrogen. It can be concluded that 23 g a contains 8 g of oxygen. In a + O2 = CO2 + h2oco2, the mass of C is 44 × (12 / 44) = 12 g, and all C comes from a
What is the mass ratio of carbon in carbon monoxide and carbon dioxide of the same mass?
If you know the answer, please scare me,
Co 12:16 contains C 12 / (12 + 16) CO 2 12:32 contains C 12 / (12 + 32) suppose that the mass ratio of carbon monoxide and carbon dioxide is 1 * 12 / (12 + 16)
