Using the bond energy data given below, which choice is closest to the enthalpy change for the combustion of one mole of acetylene, C2H2, to form carbon dioxide and gaseous water? C-H, 456 kJ/mol C=C, Assuming the enthalpy of vaporization is 10 kJ/mol and the...
The WinterOlympics venues adopted CO2 instead of Freon as a refrigerantin ice-making, which will reduce carbon dioxideemissions greatly.(作为大气中的一种元素,二氧化碳不会破坏臭氧层。虽然二氧化碳是一种温室气体,但其温室效应远低于其他合成制冷剂。冬奥会场馆在制冰时采用二氧化碳代替氟利昂作为制冷剂,将大大...
For instance, if you have a sample of 1 cubic meter of air with 0.0004 cubic meters of carbon dioxide, the ppm concentration of carbon dioxide can be determined as follows: Cabon dioxide (CO2) concentration = (0.0004 m^3 / 1 m^3) = 0.0004 (parts per part or parts per 1) To ...
It goes out. Carbon dioxide is already in the energetically most stable state; it will not support combustion of the splint. Carbon dioxide is a good..
may be found. Typically these are water vapor and carbon dioxide. If combustion is incomplete, a fire may also give off tiny solid particles of soot or ash. Additional gases may be released from incomplete combustion, especially of "dirty" fuel, such as carbon monoxide or sulfur dioxide. ...
