According to the reaction equation:
PbCrO4 ↔ Pb2+ + CrO42-
so, when the Ksp expression = [Pb2+] [CrO42-]
when the Ksp =2.8 x 10^-13
when the solubility is the amount of solute that dissolved in a unit volume of a solvent so, we can assume solubility = X
by substitution on Ksp expression:
∴2.8 x 10^-13 = X*X
∴X = √(2.8 x 10^-13)
= 5.29 x 10^-7 M
∴ the solubility = X = 5.29 x 10^-7
The total number of moles of solute particles present in 1L (exact) of aqueous 0.057 m hno3 is 0.166 mol
Initial moles of HNO3 = 1Lx 0.083 mol HNO3/1 L
The HNO3 is a strong acid that can be completely dissociated in the following way.
HNO3→H + NO
1 mol 1 mol 1 mol
The HNO3 is dissociated into two particles (Kt and NO3). So that,
total moles particles = 0.083 mol (K) + 0.083 mol (NO) = 0.166 mol
The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol.

Quartz is the type of mineral used for both mechanical and chemical weathering
Answer:
Cupric oxide, or copper (II) oxide,
Explanation:
Correct me if im wrong tnx:<
Answer:
They both alter the pH of a solution.
Explanation:
If a strong acid is added, the pH of a solution will lower. This is because more hydrogens/hydroniums are increasing in the solution. If a strong base is added, the pH will increase. This is because hydrogens/hydroniums are decreasing in the solution.
