According to Periodic Law, elements arranged in order of increasing atomic number are placed together in groups having

same valence shell configuration and properties

Explanation:

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

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
