What is the equilibrium constant for the chemical equation: N2 (g) + 3H2 (g) ↔ 2NH3 (g)

At equilibrium, the concentration of N2 is 2.5 x 10-4 M, the concentration of H2 is 6.4 x 10-3 M, and the concentration of NH3 is 5.3 x 10-2 M.

Write out the equilibrium constant, Keq, and show you work.

Where are chemicals found at work? a. only in cleaning products b. only in carpets and paint c. in every area of work d. only in food preparation submit

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
