Metallic bond
Metals are bound together by metallic bonds characterized by the sharing of free electrons among a lattice of the metal ions. This type of bonding gives metals unique properties such as strength, ductility, malleability, electrical and thermal conductivity, opacity, and luster.
This property of metal to be flattened and shaped is called malleability. When stress is applied to the metal, its atoms merely roll or slide over each other into new positions while keeping the metallic bond intact. The bonds do not break, thereby allowing the metal to be flattened out instead of crumbling or breaking into pieces.
<span>3.75 gallons need to be drained and replaced with bleach.
Change the problem to "What amounts of a 100% solution and a 4% solution is needed to make 90 gallons of a 8% solution?" Given that, we'll use the following values.
x = amount of 4% solution.
90-x = amount of a 100% solution.
The equation to solve then becomes.
0.04 x + (90-x) = 0.08 * 90
0.04 x + 90 - x = 7.2
Add x to both sides
0.04x + 90 = 7.2 + x
Subtract 0.04x from both sides
90 = 7.2 + 0.96x
Subtract 7.2 from both sides
82.8 = 0.96x
Divide both sides by 0.96
86.25 = x
So you now know that you need 86.25 gallons of the original 4% solution and (90-86.25) = 3.75 gallons of the bleach to make the desired 90 gallons.
So simply drain 3.75 gallons from the tank and replace with bleach.</span>
Cause latin name of Pb is plumbum.
The same K - potassium - latin name is kalium.
Answer: The suffixes of the names of polyatomic ions have a pattern associated with them. ... For example, the sulfite ion has three oxygen atoms whereas the sulfate ion has four oxygen atoms.
