Water with an alkalinity of 2.00 X 10^-3 equivalents/L has a pH of 7.00. Calculate [CO2], [HCO3-], [CO3^2-], and [OH-].
Nitrogen and hydrogen gases react to form ammonia gas. N2(g) + 3 H2(g) 2 NH3(g) At a certain temperature and pressure 1.4 L of N2 reacts with 4.2 L of H2. If all the N2 and H2 are consumed, what volume of NH3, at the same temperature and pressure,..
Background: If aqueous NaOH is added to tert-butyl chloride acetone solution, initially the solution is basic due to the hydroxide ions from the NaOH.
oes this result mean that the change in enthalpy of this process must be negative in order for the process to be spontaneous under standard state conditions? How come?
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. C(s) + O2(g) ----> 2CO(g)
