Hey there!:
Given the reaction:
NaBr ⇌ Na⁺ + Br⁻
↓ ↓ ↓
0.150M 0.150M 0.150M
AgBr ⇌ Ag⁺ + Br⁻
↓ ↓ ↓
x x 0.150M
Therefore:
Ksp = x * 0.150
x = ( 7.7 * 10⁻¹³ ) / 0.150
x = 5.1 * 10⁻¹²
Answer B
Hope that helps!

Answer:
exemples of elements with 1 valence electron: Hydrogen, lithium, potassium.
exemples of elements with 2 valence electrons: magnessium, calcium.
boron has 3 valence electrons. Phosphorus has 5 valence electrons.
carbon has 4 valence electrons.
exemples of elements with 5 valence electrons: Phosphorus, nitrogen
exemples of elements with 7 valence electrons: fluorine, chlorine
exemples of elements with 8 valence electrons: helium, argon
Explanation:
the easiest way to know the number of electrons are by the number of the group so 14 is 4, 16 is 6.
