Asample of solid ammonium chloride was placed in an evacuated chamber, and then heated causing it to decompose according to the following reaction: nh4cl(s) nh3(g) + hcl(g) in a particular experiment the pressure of nh3(g) in the container was found to be 2.2 atm. calculate the value of kp for the decomposition of nh4cl(s) at this temperature. kp = submitshow hints

Kp = 4.84

Explanation:

Considering the ICE table for the equilibrium as:

                     NH₄Cl (s)      ⇔         NH₃ (g) +      HCl (g)

t = o              

t = eq                                                 x                      x

--------------------------------------------- --------------------------

Moles at eq:                                      x                      x

Given the pressure of NH₃ at equilibrium = 2.2 atm

x = 2.2 atm

The expression for the equilibrium constant is:

So,

x = 2.2 atm

Thus,  

Thus, Kp = 4.84

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
