Chemistry
1 answer:
Over [174]3 years ago
8 0

In electron capture, an atomic electron is absorbed by a proton in the nucleus, turning the proton into a neutron. The electron starts as a regular atomic electron, with its wavefunction spreading through the atom and overlapping with the nucleus.

Hopefully this is helpful sorry for no explanation i am not good at explaining things

What is the percent composition by mass for sodium (Na) in sodium phosphate (Na3PO4)? % Na = (______/______)x100% = _______% NNA
ozzi

The percent composition by mass for sodium (Na) in Sodium phosphate (Na₃PO₄) : 42.07%

<h3>Further explanation</h3>

Given

Compound of Sodium phosphate (Na₃PO₄)

Required

The percent composition by mass for sodium (Na)

Solution

<em>The Comparative Law (Proust ) : compounds are formed from elements with the same Mass Comparison</em>

MW Na₃PO₄ = 163,94 g/mol

Ar Na=22,989769g/mol

\tt \%mass~Na=\dfrac{3.Ar~Na}{MW~Na_3PO_4}\times 100\%\\\\\%mass~Na=\dfrac{3\times 22.99}{163.94}\times 100\%\\\\\%mass~Na=42.07\%~Na

The 3rd answer down.

Na²O (sodium oxide) will be a base when exposed to water H²O

Explanation:

Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).

The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.
