The actual size of something times the magnification is equal to the size of the appearance of the object in the image. Therefore, to find the magnification, divide the size of the image by the actual size of the object.
The solubilty product (Ksp) of PbCl₂ : Ksp = [Pb²⁺][Cl⁻]²
<h3>Further explanation</h3>
Given
PbCl₂ compound
Required
The solubilty product (Ksp)
Solution
Ksp is the product of ions in an equilibrium saturated state
For reaction :
AₓBₐ (s) ⇔ aAᵃ⁺ (aq) + b Bᵇ⁻ (aq)
Can be formulated :
Ksp = [Aᵃ⁺] ᵃ [Bᵇ⁻] ᵇ
For PbCl₂ :
PbCl₂(s)⇔Pb²⁺(aq) + 2Cl⁻(aq)
Ksp = [Pb²⁺][Cl⁻]²
Answer:
c.)the reactants have the same mass as the products
Explanation:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

We will assume that the sodium atom closely approximates a sphere. So the expression for the volume of a sphere is
V = 4/3 pi r^3
V = 4/3 pi (186 pm)^3
V = 4/3 pi 6434856 pm^3
V = 26954261.78 pm^3
Round to 3 significant figures, giving 2.70x10^7 pm^3</span>
