a mixture of 10cm3 of methane and 10cm3 of enthane was sparked with an excess of oxygen. after coolin to room temp, the residual gas was passed thru aq KOH. what volume of gas was absorbed by the alkali ? Write the equations for CH4 + O2 and C2H6 + O2. Balance them. Look to ...

Check all this work. Check my thinking. C3H8 + 5O2 ==> 3CO2 + 4H2O 2C2H6 + 7O2 ==> 4CO2 + 6H2O Ratio propane is 1 mol C3H8 to 3 mols CO2. Ratio ethane is 1 mol C2H6 to 2 mols CO2. The total mols CO2 produced is 5 mols; therefore, 3/5 x total mols = mols CO2 from C3H8 and...

I have to solve this combustion problem using Dimensional Analysis and molar heat: 2 C2H6 +7O2 yields 4 CO2 + 6H2O + 3120 kJ The question is to discover how much heat is produced along with 8 moles of water in this reaction. My problem is that I have no idea how to go about ...

How many moles of ethane does it take to produce 8112 KJ in the reaction 2 C2H6 + 7O2 yields 4 CO2 + 6 H2O + 3120 KJ? I got 8112 kJ x 2 moles ethane/3120 kJ (5.2 moles).

Start with the chemical equations of the complete combustion of CH4 and C2H6, CH4 + mO2 -> CO2 + 2H2O ....(1) C2H6 + nO2 -> 2CO2 + 3H2O ....(2) Calculate the total mass of CO2+H2O produced if all 13.43g of gas were CH4. Do the same for C2H6. Find the ratio of each gas by...

n = PV/RT so the ratio is (PV/RT)of CO2 = (PV/RT)gases Since V, R, and T are constant, then the ratio is simply PCO2/Pgases = 346/294 = ?? The problem doesn't ask for it but you can calculate the PCH4 and PC2H6 if you wish as below. I wouldn't have done this but I misread the ...

When O2 reacts with C2H6, according to the equation: 2 C2H6 + 7 O2 = 4 CO2 + 6 H2O, how much CO2 is produced from 60.0 g of C2H6?

Here are the equations and some explanation. CH4 + 2O2 ==> CO2 + H2O 2C2H6 + 7O2 ==> 4CO2 + 6H2O -------------------------- The first equation is x + y = 30 Here is how you get the second equation. x cc CH4 gives x cc CO2 x cc CH4 USES 2x O2. y cc C2H6 gives 2y cc CO2 y ...

You can take a short cut when dealing with all gases. The short cut is that you can deal directly with volume and not convert to mols. But to complicate matters this is a limiting reagent problem. First convert L ethane to L CO2. L CO2 = 15.9 L C2H6 x ( 4 mols CO2/2 mols C2H6...

a. 16L C2H6 x (4 mols CO2/2 mols C2H6) = ? mols CO2. b and c are done the same way. d. 1416 kJ/mol x [(16 L) x (1 mol/22.4L)]

C2H6(g) + O2(g) CO2(g) + H2O(g) (a) Consider the unbalanced equation above. What is the maximum mass of CO2 that can be produced when 21.0 g of C2H6 and 38.5 g O2 react? (b) If 24.7 g of carbon dioxide is actually produced by the reaction in part (a), what is the percent yield...
