What reason best explains why metals are shiny

Chemistry

Metals are shiny because of their electrons. These electrons produce light when they come in contact with light. I hope this helps.
Elanso [62]3 years ago

The shiny appearance of a metal is most closely related to the metal's highly mobile valence electrons. In metallic bonds, the mobile electrons surrounding the positive ions are called a(n) electron sea. As light strikes the surface of a metal, the electrons in the electron sea absorb and re-emit the light.
I hope this helps.

Silver bromide (AgBr) has a solubility of 7.07 × 10^-7 mol/L
kirill115 [55]

a. AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b.  Ksp AgBr = s²

c. 5 x 10⁻¹³  mol/L

<h3>Further explanation</h3>

Given

solubility AgBr = 7.07 x 10⁻⁷ mol/L

Required

The dissolution reaction

Ksp

The solubility product constant

Solution

a. dissolution reaction of AgBr

AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b. Ksp

Ksp AgBr  = [Ag⁺]  [Br⁻]

Ksp AgBr = (s) (s)

Ksp AgBr = s²

c. Ksp AgBr = (7.07 x 10⁻⁷)² = 5 x 10⁻¹³  mol/L

NaBr + CaF2 → NaF + CaBr2 What coefficients are needed to balance the chemical equation? A) 1,1,1,1 B) 1,2,1,2 C) 1,2,2,1 D) 2,1
elena-s [515]
D.
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:

2Na                        2Na
2Br                         2F
1Ca                         1Ca
2F                           2Br

This is balanced.
