The Haber process is used in industry to produce ammonia from N2 and H2. A reactor contains NH3, N2, and H2 at equilibrium at 1000 K. The concentration of NH3 is 0.102 moles/liter, N2 is 1.03 moles/liter, and H2 is 1.62 moles/liter. Calculate the equilibrium constant for N2(g) + 3 H2(g) -->/<--NH3(g) at 1000 K
60.0 mL portion of of 1.70 M solution is diluted to a volume of 288 mili litres. A 144-mili litres portion of that solution is diluted using 115 mLili litres of H2O. Determine the final concentration.
According to the Bronsted-Lowry definition, which chemical in the following reaction is the acid? CO32- + H2O -> OH- + HCO3
What must that mean in terms of Light absorption and transmission and in terms of the energy associated with any molecular orbital transitions in indium antinomide?
draw the lewis structure of CCL2S
The decomposition of SO_2_Cl_2_ is first order in SO_2_Cl_2_ , and the reaction has a half-life of 245 min at 600 K. If you begin with 3.6e-3 mol of SO_2_Cl_2_ in a 1.0-L flask, how long will it take for the sample to decrease to 3.2e-4
The HCl turns the indicator red and the NaOH turns the indicator purple, but what happens to the indicator when the 2 solutions are mixed? Also, is there a temperature increase with the reaction?
On a smoggy day in a certain city the ozone concentration was 0.54 ppm by volume. Calculate the partial pressure of ozone and the number of ozone molecules per liter of air if the temperature and pressure
A 309 mL sample of unknown HCl solution reacts completely with Na_2CO_3 to form 10.1 g CO_2. What was the concentration of the HCl solution?
A weak monoprotic acid is titrated with NaOH and the following data is recorded. Calculate the molar mass of the weak acid.
The melting point of tropylium bromide is above 200 degree C, quite high for an organic compound. How can you account for these experimental observations?
The concentration of an enzyme within a cell is extremely low relative to other material present, yet functions effectively in its metabolic role.
