seawater - formed by the precipitation of minerals from the ocean's water. :)
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>
I hope it helps!
Answer:
They are all alkali earth metals.
Explanation:
Their valence shell each has 2 electrons. Also, they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. They form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust.

Answer: He had more than one independent variable.
Explanation: It would only be fair, if both plants were in a sunny window, because then, it would be easier to see if the fertilizer actually affected the plants. This is because there is always a chance that the lack of sunlight decreased the number of flowers on the plant, instead of the fertilizer. It is always better to just have one independent variable.
