Answer:
because a mosquito net prevent mosquito bites
Ionization energy is the energy required to remove the
outermost electron from one mole of gaseous atom to produce 1 mole of gaseous
in to produce a charge of 1. The greater the ionization energy, the greater is
the chance f the electron to be removed from the nucleus. In this casse, Radium
has the largest ionization energy.
The computation for this problem is:
(1.55x10^4 / 1.0x10^3) x 19.8 mm Hg
= 15.5 x 19.88 mm Hg
= 308.14 mm Hg decrease
= 308.14 x 0.05 C = 15.407 deg C
deduct this amount to 100
100 – 15.407 = 84.593 C
ANSWER: 85 deg C (rounded to 2 significant figures)
