Answer:
identify and name the landforms in the following diagrams
Answer is: <span>fewer drops of 6 M sulfuric acid, because concentration of H</span>⁺ is greater than in hydrochloric acid with same concentration.<span>
</span>
Chemical dissociation of hydrochloric acid in water:
HCl(aq) → H⁺(aq) + Cl⁻(aq).
Chemical dissociation of sulfuric acid in water:
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).
From chemical reaction: c(HCl) = c(H⁺) = 6 M.
c(H⁺) = 2c(H₂SO₄) = 2 · 6 M = 12 M; concentration of hydrogen cations.
There’s only one measurement the question doesn’t make sense
Answer: C
Explanation:
The one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals.
