I can only find 2, I hope this helps
-To deliver oxygen to the cells of the body's tissues and remove carbon dioxide.
- The lungs also remove carbon dioxide from the blood. If carbon dioxide built up in a body, death would result.
<span>Answer:
Yes, the n for potassium would be 4, and for neon would be 2.
Just count which row of the periodic table you are on.
The "L" tells you whether the highest-energy electron is in
an "s" orbital (L=0) or a "p" orbital (L=1) or a "d" orbital (L=2) or an "f" orbital (L=3).
The manner in which these orbitals are filled is:
for each of the first three rows (up to argon),
two electrons in the "s" orbital are filled first, then 6 electrons in the "p"orbitals.
The potassium row also starts with filling the "s" orbital at the new "n" level (4)
but then goes back to filling up the "d" orbitals of n=3 before it fills up the "p"s for n=4.
OK, so potassium has n=4, L = 0, while neon has n=2, L = 1.
The quantum numbers connected with "an element" are always referring to the
highest-energy electron, i.e., the one that was absent in the predecessor element
of the periodic table. When you go from potassium to calcium,
you still get n=4, L = 0, because there are two positions in the "s" orbital.
But when you go from calcium to scandium, suddenly you go back to n=3, L = 2 ("d" orbital).</span>
Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. ... Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1.
Answer:
The concentration of hydrochloric acid would be estimated to be less.
Explanation:
This is because, the hydroxyl ions from water react with the hydrogen ions from the hydrochloric acid, hence decreasing the moles of hydrogen ions which lowers the acidic strength of Hydrochloric acid.
