The reaction of methane and water is a way to prepare hydrogen according to CH4(g)+H2O=CO2(g)+H2(g) a) If 995 g of CH4 reacts with 2510 g of water, how many moles of reactants and products are there when the reaction is finished? Identify the limiting reagent in the reaction. b) if only 228 g of H2 are produced what is the % yield of the gas?
The compound known as butylated hydoxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.376 g sample of BHT was combusted in an oxygen rich environment to produce
1.664 g of a solid white acid are dissolved in water and completely neutralized by the addition of 45.37 mL of 0.580 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.
Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
what is the change in enthropy for this process in kJ/K*mole. The atomic mass of oxygen is 16.00.
which gas sample contains the largest number of mole?
Explain the following observations. 1. Aziridines, compounds that contain nitrogen in a three-membered ring, undergo pyramidal inversion much more slowly than do other alkylamines.
If composite, define each simple sub-system and the internal restraint. If the vessel is shaken vigorously. Is the system then a simple or composite system?
For the cyclohexanes substituted in the positions indicated, identify the substituents as either axial or equatorial in chair conformers. For example, a 1,2-cis relationship means that one substituent must be axial and one equatorial.
with wet beriberi, peripheral vessels dilate and cardiac muscle looses its contractility. also, alpha-ketoglutarate is found in high concentrations. this is thought to be caused by
What is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.406 mol of NaA in 2.00L of solution? The dissociation constant of is 5.66*10-7
What are the molality and mole fraction of solute in a 34.0 percent by mass aqueous solution of formic acid (CH3OH)?
The overall equilibrium involves Ksp, Ka3 of phosphoric acid and Kw. Construct the constant and show the three equations that apply.
