D) The organism was able to transport water through specialized veins
Barium :
with +2 being the charge
Oxygen :
with -2 being the charge
The given equation can be written as:
Ba + O = BaO
Since the sum charges of Barium and Oxygen equals 0, there is no need to add subscripts.
Both Ba and O appear on the left and right side of the equation once, so there is no need to add a coefficient.
Ba + O = BaO is balanced
The answer is a. concentrated. (If the statement was instead that large amounts of water was involved and smaller amounts of salt, the answer would be instead c. dilute)
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.
