The equilibrium constant is 8.8 x 102 at a particular temperature for the reaction: H2(g) + I2(g) ⇌ 2HI(g) Use this information to decide what will happen, given the following sets of initial conditions: Will the reaction shift to the left, to the right or will the system be at equilibrium? A 4.0 L flask contains 1.17 mol H2, 0.083 mol I2 and 8.11 mol HI. A 2.0 L flask contains 0.0455 mol H2, 0.012 mol I2 and 0.693 mol HI. PH2 = 0.5380 torr, PI2 = 0.066 torr, PHI = 5.59 torr PH2 = 0.47 torr, PI2 = 0.061 torr, PHI = 5.99 torr

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.

Before it was launched, a helium-filled balloon had a pressure of 201 kpa at a temperature of 27°c. at an altitude of 15,000 m, the pressure had decreased to 2.5 kpa and the temperature had dropped to -14 °c. the volume of the balloon increased to 59.3 m3. what is the original volume of the balloon? 13 m3 0.85 m3 0.077 m3 1.17 m3
