What things can the atomic radiation help us with
Triss [41]
Chemotherapy is when radiation is used to kill cancer cells while sparing healthy tissue cells, also doctors sometimes inject patients with a nuclear tracer to show problematic areas that need to be checked out, and Nuclear power plants use nuclear energy to create a large amount of energy from just a small amount of Uranium. These are just some of the ways nuclear radiation is used to help us.

The molar solubility of pbi2 is 1.5 103 m.
Vsevolod [243]

Answer: -

Concentration of PbI₂ = 1.5 x 10⁻³ M

PbI₂ dissociates in water as

PbI₂ ⇄ Pb²⁺ + 2 I⁻

So PbI₂ releases two times the amount of I⁻ as it's own concentration when saturated.

Thus the molar concentration of iodide ion in a saturated PbI₂ solution = [ I⁻] =

= 1.5 x 10⁻³ x 2 M

= 3 x 10⁻³ M

PbI₂ releases the same amount of Pb²⁺ as it's own concentration when saturated.

[Pb²⁺] = 1.5 x 10⁻³ M

So solubility product for PbI₂

Ksp = [Pb²⁺] x [ I⁻]²

=1.5 x 10⁻³ x (3 x 10⁻³)²

= 4.5 x 10⁻⁹

Looking at the Periodic Table, how can you determine if an element is a metal, metalloid or nonmetal?
Digiron [165]

Answer:

It depends on where it's located on the periodic table.

Explanation:

Metals are on left side of the periodic table except Hydrogen (H), which is a nonmetal, then there's the staircase, which has the metalloids, and on the right of the staircase are the nonmetals.
