The equilibrium concentrations for the reaction between carbon monoxide and molecular chlorine to form COCl2
(g)
at 740C are [CO] = 0.012 M, [Cl2
] = 0.054 M, and [COCl2
] =
0.14 M. Calculate the equilibrium constants Kc and Kp

the answer for sodium is 0.186

the answer for rubidium is 0.251

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
