Answer:
Explanation:
When two non-miscible liquids are put together, the one with the higher density will be on the bottom, while the one with the lower density will be on top.
Meaning that in this problem's case toluene would be on the top layer and water in the bottom layer.
It is a solution, because it's the alloy of tin and copper
Copper<span>(II) </span>oxide<span> or cupric </span>oxide<span> is the inorganic </span>compound<span> with the formula CuO. A black solid, it is one of the two stable </span>oxides<span> of </span>copper, the other being Cu2<span>O or cuprous </span>oxide<span>. As a mineral, it is known as tenorite and paramelaconite.</span>
Answer:
Sodium Chloride has Ionic bond while Hydrogen Chloride has covalent bond.
Explanation:
Na has 11 electrons (2, 8, 1) and need to give away 1 electron to be stable
Cl has 17 electrons ( 2, 8, 7) and needs 1 electron to be stable.
Na transfers 1 electron to CL to form Ionic bond.
While
Hydrogen has 1 electron and shares with Chlorine to be stable.
Covalent bond involves sharing.
