If a sample of H2S gas has a volume of 5.60 L at STP, how many moles of H2S are in the sample? What is mole? How to calculate the number of moles? Determine the number of moles of C in 2.1 moles of CH4. Calculate the number of moles of helium gas used to inflate...
The combustion of ethane (C2H6) produces carbon dioxide and steam: 2C2H6(g) + 7O2(g) \rightarrow 4CO2(g) + 6H2O(l) How many moles of CO2 are produced when 5.35 mol of ethane are burned in an excess of oxygen? The combustion of ethane (C2H6) produ...
A 3.43 L flask is filled with carbon monoxide at 27^oC and the pressure is 8.31 atm. Calculate the total pressure after 2.09 moles of carbon dioxide has been added to the flask. (R=0.082 L-atm/K mol) If 1.00 moles of CO2...
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/...
(iii)Correct expressionNote:138.2 or 39.1 must be seen Allow expression to be shown in two(or more) steps x given as correct integer from candidate's expression(c)Any 2 of the following:·Heat water(before collecting gas)·Saturate water with CO2(before collecting gas)·Collect the gas ...
A 0.30-mol sample of copper metal and 10.0 mL of12 Mnitric acid are mixed in a flask. How many moles of NO gas will form? A.0.060 mol B.0.030 mol C.0.010 mol D.0.20 mol 10.Gold(III) oxide, Au2O3, can be decomposed to gold metal, Au, plus oxygen gas, O2. How many moles ...
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...
How many moles of C2H2 are needed to form 0.54 mol of CO2? 2 C_2H_2 + 5 O_2 \to 4 CO_2 + 2 H_2O How many grams of H_2O are formed from 0.84 mol of C_2H_2? How many moles of ethane (C2H6) would be needed to react with 62.3 grams of oxygen gas? How ...
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 ...
another type. In other words, a single molecule of a heavier MW (let's say CO2) could have a higher rate than that of a lighter weight MW (let's say O2). However, the average rate of all of the O2molecules within the gas, will have a higher rate in comparison to the CO2...
