Answer A
hope this helps!
Answer:
H3O^+ < HClO2 < H3PO4< HCOOH < H2PO4^-<CIO2^-<H2O< HCOO^-
Explanation:
The pH of a solution refers to the negative logarithm of it's hydrogen ion concentration. Generally, the hydrogen ion concentration of an acid is always greater than that of its conjugate base. Hence, the conjugate acid always has a lower pH than the conjugate base.
This can be seen in the species, H3O^+ and H2O, HClO2 and ClO2^- etc.
Answer:
<h3>The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix.</h3>
Answer is: <span>3 particles would one formula unit of CaCl</span>₂<span> produce when dissolved in solution.
Chemical reaction of calcium chloride dissolving in water:
CaCl</span>₂(aq) → Ca²⁺(aq) + 2Cl⁻(aq).
<span>There are one calcium cation and two chlorine anions in solution from one formula unit of calcium chloride.</span>
