所以n(CO2)=0.032% * n=1.60 mol我把那atm当做标准大气压来算 作业帮用户 2017-10-04 举报 你好!题的翻译:圆柱体A的体积V为12.3L, 压强P为 1.0 大气压,温度T为 300K圆柱体A中的二氧化碳分子数量为多少?根据理想气体方程 PV=nRTAccording to the Ideal Gas Equation PV = nRT我们可以推断出 n = PV/...
Question: How many moles of carbon dioxide gas are expected to be produced from the complete reaction of 27.7 g of ethane? Preparation of Carbon Dioxide: Carbon dioxide is a harmful gas for mankind. In the laboratory, it is prepared through the chemical...
How many moles of carbon dioxide will be formed upon the complete reaction of 0.989 moles of carbon monoxide with excess oxygen gas? Under certain circumstances, carbon dioxide, CO2(g), can be made to react with hydrogen gas, H2(g), to p...
6. If we combine nitrous oxide (NO, laughing gas) with oxygen (O2) we produce nitrogen dioxide (NO2) according to the following reaction: 2NO + O2→ 2NO2 How many grams of NO2 will be produced when 5.00 moles of NO react?
This particular study, inspired by the spaceship crash that would have seen the animals blasted into the surface of the moon, actually packed tardigrades into a nylon bullet and fired them out of a two-stage light gas gun — which uses gunpowder and highly compressed hydrogen to fire ...
■ (g) gas ■ (aq) aqueous (a solution in water). State symbols are written after the formula of each reactant and product. For example: ZnCO3(s) + H2SO4(aq) --> ZnSO4(aq) + H2O(l) + CO2(g) Question13 Write balanced equations, including state symbols, for the following ...
A 10.00 L vessel containing CO2 has an internal pressure of 20.0 atm at 273 K. Calculate the number of moles of gas using the virial equation. Problem on Gas Equation: The general gas equation gives us a relationship between physic...
BMeasuring the number of moles of a gas In the ideal gas law, the symbol n represents the number of moles of gas. My question is how, given a volume of a certain gas, one determines how many moles one has. My understanding is that a mole in this case denotes a quantity of particle...
Using the molar gas volume In 1811 the Italian scientist Amedeo Avogadro suggested that equal volumes of all gases contain the same number of molecules. This is called Avogadro's hypothesis. This idea is approximately true as long as the pressure is not too high or the temperature too low. ...
