Gaseous hydrogen iodide is placed in a closed container at 425°c, where it partially decomposes to hydrogen and iodine: 2hi(g)⇌h₂(g)+i₂(g) at equilibrium it is found that [hi]= 3.51×10⁻³ m, [h₂]= 4.76×10⁻⁴ m, and [i₂]= 4.76×10⁻⁴ m.
what is the value of at this temperature? express the equilibrium constant to three significant digits.

Which of the following is not a true statement about dwarf planets? a the kuiper belt contains comets, asteroids, and dwarf planets. b ceres is a dwarf planet located in the kuiper belt. c the largest known dwarf planet in the solar system is named eris.

What type(s) of intermolecular forces are expected between ch3ch2cooh molecules? dipole forces, induced dipole forces, hydrogen bonding

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
