Answer:
1s^2..2s^2..2p^6..3s^1
Explanation:
Since sodium has 11 electrons...its electron configuration is...;
1s^2..2s^2..2p^6..3s^1
;The powers of the energy levels(i.e s,p,d) should all add up to the number of electrons in an atom
*.When writing...please do not separate them.
Answer:
O.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> O goes from 0 to -2, so, it is the element that is reduced.</em>
Answer:
P₂ = 0.205torr
Explanation:
Boyle's law relates the pressure and volume of a gas under two different conditions. The equation is:
P₁V₁ = P₂V₂
<em>Where P is pressure and V volume of of 1, initial conditions and 2, final conditions.</em>
P₂ is our incognite
Replacing:
P₁V₁ = P₂V₂
8.20x10⁴torr*15.0L = P₂*600x10⁴L
<h3>P₂ = 0.205torr</h3>
