what are the equilibrium concentration of N2 C. If the initial concentration of NO is 0.177M , what are the equilibrium concentration of O2
125 mole of oxygen gas is added to carbon in a .25L container. The mixture equilibriates at 500K. Calculate the equilibrium concentration of carbon monoxide, knowing that K=.086 at 500K.
Draw the structure of the carbocation intermediate leading to the formation of 3-methyl-1-butene. Use the (+) and (-) tools to adjust charges as necessary
Trimethylamine, (CH3)3N: reacts readily w/diborane, B2H6. The diborane dissociates to two BH3 fragments, which can react w/trimethylamine to form complex, (CH3)cN:BH3. Write an equation for this reaction and interpret it in terms of Lewis acid-bas..
