Answer:

conduct electricity

are malleable

Explanation:

Metals conduct electricity because they have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. This allows the delocalized electrons to flow in response to a potential difference.

And since metals don't tightly hold on to electrons during metallic bonding, they are easily replaced. In metallic bonding, electrons are delocalized and move freely among nuclei. When a force is exerted n the metal, the nuclei shift, but the bonds do not break, giving metals their characteristic malleability.

A buffer is prepared by adding 20.0 g of sodium acetate to 480 ml of a 0.160 m acetic acid solution. determine the ph of the buf
docker41 [41]
Hello!

The chemical reaction for the dissociation of Acetic Acid is the following:

CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺

To solve the problem we are going to use the Henderson-Hasselbach Equation, as follows, but first we need to know the pKa:

pKa=-log(Ka)=-log( 1,8*10^{-5} )=4,74

pH=pKa + log( \frac{[CH_3COO^{-} ]}{[CH_3COOH]} )

pH=4,74+log( \frac{\frac{20 g CH_3COONa }{0,480 L}* \frac{1 mol CH_3COONa}{82,03 g CH_3COONa}  }{0,160 M} )=5,24

So, the pH of this solution is 5,24

Have a nice day!
