B, only metals. Metallic bonding always occurs between metals of the same element and involves “a sea of mobile electrons”
<span>Answer: Potassium hydroxide, KOH, is considered a BASE in an acid-base reaction because it ACCEPTS a hydrogen ion from the other reactant.
According to </span><span>Brønsted–Lowry acid–base theory, Base is a specie which accepts proton (H</span>⁺) while, Acid is a specie which donate proton.
Bases may contain a negative charge or lone pair of electrons, while, Acids contain positive charge or a neutral atom with incomplete octet.
In given statement KOH is acting as a base because it contains a negatively charged hydroxyl group which can accept proton from a acid, i.e.
KOH → K⁺ + OH⁻
Reaction of OH⁻ with any acid,
K⁺ + OH⁻ + HCl → H₂O + KCl
4 x 
in dL will be 4 x 
<h3>Conversion from dL to cm^3</h3>
Recall that:
Deci =
Centi = 
Thus, 1 dl = 100 ml
This means that converting from dl to requires multiplying by 
.
Applying this principle, 4 x in dL to will be:
4 x x = 4 x
Therefore, 4 x dl will be 4 x
