Answer:
AuCl
Explanation:
The solubility product constant, ksp, is defined as:
MₓYₙ(s) ⇄ xMⁿ⁺(aq) + nYˣ⁻(aq)
ksp = [Mⁿ⁺]ˣ + [Yˣ⁻]ⁿ
Thus, the higher ksp, the more soluble the compound is. Thus, the lower ksp the less soluble the compound is precipitating first. As the lower ksp is for Au, the first compound in precipitate is <em>AuCl</em>

<u>Answer:</u>
<u>For a:</u> The chemical equation for the dissolution of sodium carbonate is
<u>For b:</u> The net acid-base reaction is
<u>Explanation:</u>
Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form aqueous solution.
The chemical equation for the dissolution of sodium carbonate follows:
Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.
The chemical equation for the ionization of sodium carbonate follows:
Now, the anion formed which is reacts with water to form conjugate acid.
The chemical equation for the reaction of anion with water follows:
Hence, the net acid-base reaction of the anion formed and water is written above.
Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.
Answer:
water pulling a compound apart and then surrounding the broken pieces/ions (this is what dissolving is)
Explanation:
As we know, water is a polar solvent. What this means is that water can effectively interact with ions in an ionic substance owing to its large dipole moment.
Now, when an ionic substance is dissolved in water, the positive end in water pulls hard on the negative ion of the ionic substance while the negative end in water pulls hard on the positive ion of the ionic substance.
The ionic substance is eventually pulled apart and surrounded by water molecules. This is how an ionic substance is dissolved in water.
