Noble Gas. Metals have 1 or 2 Valence Electrons. Halogens have 7 Valence Electrons. Semi-Metals can have different amounts.
For one a homogenous mixture cannot be separated using filtration. Hope this helps:)
B.) Colligative properties depend on <span>the number of particles present in the solution.

Answer:
50,000,000 Hz
Explanation:
<em>Rearrange the formula:</em>
wave speed = frequency × wavelength → frequency = wave speed ÷ wavelength
wave speed = 300,000,000m/s
wavelength = 6m
<em>Substitute in the values:</em>
frequency = 300,000,000 ÷ 6
frequency = 50,000,000 Hz
Hope this helps!

A: Not correct. One reactant is dissolved in water. The other is a solid that combines with the one reactant that is in water. That's what aqueous (aq) means.
B: CuCl2 is aqueous (the equation says so) ClCl2(aq) means that the copper chloride is in water. Whatever else B says, this much is true so that Statement B is false.
C: False. The reactants contain a liquid and a solid.
D: True. The statement is true because CuCO3 is labels as a solid(s), and CO2 is labeled as a gas (g).
E: is false. Where is the solid in the products?
Right Panel
Sample Mass: 33.5 grams
Volume: 3.2 cm^3
Density = mass / volume
Density = 33.5 / 3.2 = 10.47.
It can only be silver.
