What factors do the valencies of transition elements depend upon? At least 2 points.

Explanation:

1. No of electrons present in d subshell.

2. comparable energy between( n-1)d sub shell and ns subshells.

n=no of shells.

electrons from (n-1)d subshells are lost as easily as from ns subshell.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
