For lead fluoride Ksp = s³
For Aluminum hydroxide Ksp = s⁴
<u>Explanation:</u>
The expression for the solubility product can be written as the product of the concentration of the ions present in the solution.
PbF₂ → Pb²⁺ + 2 F⁻
Then the Ksp can be written as,
Ksp = [ Pb²⁺] [F⁻]²
If the concentration can be considered as s, then the Ksp can be written as,
Ksp = s× s² = s³
For Aluminum hydroxide on dissociation it gives 4 ions as,
Al(OH)₃ → Al³⁺ + 3 OH⁻
Ksp = [Al³⁺] [OH⁻]³
= s × s³ = s⁴
Thus,For lead fluoride Ksp = s³
For Aluminum hydroxide Ksp = s⁴
Answer:
The composition of a nuclide (atomic nucleus) is defined by the number of protons Z and the number of neutrons N, which sum to mass number A.Proton number Z, also named the atomic number, determines the position of an element in the periodic table.The approximately 3300 known nuclides are commonly represented in a chart with Z and N for its axes and the half-life for radioactive decay
Explanation:
According to the equation of molarity:
Molarity= no.of moles / volume per liter of Solution
when we have the molarity=0.58 M and the beaker at 150mL so V (per liter) = 150mL/1000 = 0.150 L
by substitution:
∴ No.of moles = Molarity * Volume of solution (per liter)
= 0.58 * 0.150 = 0.087 Moles
Answer:
b. aluminum
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.
Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.
Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:
<h3>b. aluminum

Answer:
Option (e) should be discarded.
Explanation:
The given set of data is said to be precise if the values are close to each other. In this problem, a chemistry student is experimentally determining the boiling point of bromine.
In this case, all values are close to each other but option (e) i.e. 56.3° should be discarded to make his data precise.
