Metamorphic rock. This is because when heat is projected onto these rocks, they morph into different metamorphic rocks.
1) - dissolving ammonium nitrate in water to cool the water.
2) Pressure
3) - a liquid with a high specific heat
4) -Melting ice cubes
5) - the enthalpy is positive
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
<h3><u>
What is electronic configuration ?</u></h3>
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.

Answer:
118.6nm
Explanation:
It is possible to calculate wavelength of any energetic process (As an ionization) using:
E = hc / λ <em>(1)</em>
<em>Where E is Energy, h is Planck constant (6.626x10⁻³⁴Js), c speed of light (3x10⁸ms⁻¹) and λ is wavelength In meters.</em>
As the energy to ionize 1 mole of iodine is 1009kJ, one atom requires:
(1009kJ / mol) ₓ (1mol / 6.022x10²³ atoms) = <em>1.6755x10⁻²¹kJ / atom</em>. = 1.6755x10⁻¹⁸J
Replacing in (1):
λ = hc / E
λ = 6.626x10⁻³⁴Js*3x10⁸ms⁻¹ / 1.6755x10⁻¹⁸J
λ = 1.186x10⁻⁷m
As 1m = 1x10⁹nm:
1.186x10⁻⁷m ₓ (1x10⁹nm / 1m) =
<h3>118.6nm</h3>
This would be a supersaturated solution!
