It is the transition metals because the first element ever synthed was technetium, but surely you've googled this by now. ;)
Answer:
Minerals and rocks are the same. Aggregates of minerals form rocks. Minerals determine the texture of a rock. Most rocks are made of a single mineral type.
Explanation:
They must have both cations and anions.
I hope this helps.
Answer:
It doesn't disappear.
Explanation:
Water vapor does not disappear. It loses its solid form because it is warm enough, and thus becomes an invisible gas.
Chemical reaction (dissociation) of silver chromate in water:
Ag₂CrO₄(s) → 2Ag⁺(aq) + CrO₄²⁻(aq).<span>
Ksp(</span>Ag₂CrO₄) = [Ag⁺]²·[CrO₄²⁻].<span>
[</span>CrO₄²⁻] =
x.<span>
[</span>Ag⁺] =
2[CrO₄²⁻] = 2x<span>
Ksp = (2x)</span>² · x = 4x³.
Ksp is the solubility product constant <span>for a solid substance dissolving in an aqueous solution.</span>
[Ag⁺] is equilibrium concentration of silver cations.
[CrO₄²⁻] is equilibrium concentration of chromate anions.
