Answer:
The valence electrons in the metal atom in the lattice structure can delocalize and move freely. The electrons are "loosely" connected with their parent atom in the metallic bond because most metals have excess electrons in their outer orbitals above the stable configuration.
Explanation:

Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Calcium acetate [Ca(C₂H₃O₂)₂] is strong electrolytes
<h3>What is the calcium acetate's mode of action?</h3>
End-stage renal disease patients on dialysis who have hyperphosphatemia (excess phosphate in the blood) are treated with calcium acetate. By forming a bond with the phosphate in your diet, calcium acetate causes it to leave your body without being absorbed.
Heat is created as calcium acetate dissolves in water, and as the temperature rises, the solubility of the calcium acetate increases.
When heated, calcium acetate, a somewhat water-soluble crystalline calcium source, breaks down to form calcium carbonate.

<span>m1v1=m2v2
m2=(m1v1)/v2
Where m is the molarities and v is the volumes
m2=(0.500*25.0)/48.5
m2=12.5/48.5
m2=0.256 M
so it will be A: 0.256 M</span>
Answer:
<u><em>Decantation</em></u><em> by means of difference in relative densities.</em>
Explanation:
The specific gravity (relative density) of the gold to the soil/sand is the physical property exploited in panning gold. The particles with lower density would float whilst the heavier gold sinks lower to the bottom of the pan by gravity and is decanted off.
I hope this explanation is easy to comprehend.
