An inorganic chemist studying the reactions of phosphorus halidesmixes 0.1050 mol of PCl5with 0.0420 mol of Cl2 and0.0420 mol of PCl3 in a0.5000 L flask at 250°C. PCl5(g) reversible reaction arrowPCl3(g) + Cl2(g)Kc = 4.2 ...
A student weighed out 1.74 grams of sodium hydroxide pellets and added them to 48.0 grams of water in a calorimeter. Extrapolating back to the time of mixing yielded a temperature change at the time of mixing equal to 9. ...
A 3.15- sample of NH4NO3 is introduced intoan evacuated 2.26- L flask and then heated to 245 C. What is the total gas pressure, in atmospheres, in the flask at245 C when the NH4NO3 has completely decomposed?

What wavelength of light (nm) is required to eject an electron with a speed of 2.0 x 10 6 m/s from a metal with a threshold energy of 3.4 x 10 -18 J?
Why do the instructions call for using a saturated solution of NaOH rather than one at lower concentration? Why can we ignored in the calculation of the concentration of NaOH?
Calculate the dissociation constant of NH4OH(aq) if the degree of dissociation of 0.006 mol/kg solution is 0.053 and the activity coefficients of all species equal 1.
Question 1: Bonding Energy i. Draw an energy level diagram for a single Na ion and Cl ion. ii. Explain what is happening to the energy level between these two ions in terms of the Potential Energy. iii. Which process uti ...
Consider the following reaction: CO + H2 CH3OH A reaction mixture in a 5.18 L flask at a certain temperature contains 26.8 g CO and 2.36 g H2 . At equilibrium, the flask contains 8.67 g CH3OH. Calculate the equilibrium c ...
If liquid is at or above it's flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. In such a case, the liquid is already evaporating sufficiently to reach the lower flammability lim ...
