Methanol is produced commercially by the catalyzed reaction of carbon monoxide and hydrogen:CO(g) + 2 H2(g) = CH3OH(g)An equilibrium mixture in a 2.00-L vessel is found to contain 0.0406 mol CH3OH, 0.170 mol CO, and 0.302 mol H2 at 500 K. What is Kp at this temperature?
If a 88.2 gram charcoal briquette (assume pure carbon) is burned in an excess of oxygen, what mass of CO2 is produced by the reaction
Calculate the concentration of a NaOH solution if 0.1379 g of succinic acid (H2C4H4O4, 118.09 g/mol) requires 12.4 mL of NaOH solution
In this experiment we used ortho-vanillin and p-toluidine to form the imine. Why does the reaction mixture turn into a liquid when the ortho-vanillin and p-toluidine are initially mixed? What is the name or melting point of the product?
This solution is to be prepared by allowing water at a set pH to reach equilibrium with solid Fe(OH)3. What pH should be used for the aqueous solution to give this desired concentration of [Fe3+]
If you wanted to prepare a 1.45 L buffer with a total phosphate concentration of 0.0500 M, how many grams of NaH2PO4 and Na2HPO4 would you mix together? How many grams of conjugate acid do you need? How many grams of conjugate base do you need?
