Concept explainers
(a)
Interpretation:
The picture of bands that depicts highest melting point should be determined.
Concept introduction:
The band theory is used to explain hardness, electrical conductivity, melting point for different metals. It can be explained as a theory related to set of MOs that have very less energy difference between them. These sets of MOs are also known as bands. Melting point of any metal depends on occupancy of both MOs, bonding and antibonding. When the electron from bonding MO can be excessed easily relative to antibonding MO electrons, then melting point metal is higher.
(b)
Interpretation:
The picture of bands that depicts lowest melting point should be determined.

(c)
Interpretation:
The increasing order band picture with respect to hardness should be determined.

- Use the systematic treatment of equilibrium to determine the pH and the concentrations of all species in a saturated aqueous solution of SrF2. Do not include activity coefficients. The solubility of SrF2 is governed by Ksp for the salt, hydrolysis of F- and of Sr2+, and by ion pairing between Sr2 + and F-. PK(SrF2) = 8.58, PK(HF) = 3.17, pkw = 14.00, pk for the formation of (SrOH+) = 13.18, pk for the formation of (SrF+) = 0.14 Show all your work and upload your answers here. 1 - Write the pertinent reactions. 2 - Write mass balance and charge balance equations. 3 - Write the equilibrium constant expressions. 4 - Count the equations and unknowns. 5- If the problem is solvable make suitable approximations and find the concentrations and the pH.arrow_forwardPlease correct answer and don't use hand ratingarrow_forwardHow might you prepare each of the following using a nucleophilic substitution reaction at some step?

(Note: Arsenate = AsO4³-) In the presence of aqueous ammonia, solid Manganese(II) Arsenate becomes more soluble and aqueous tetraamminemanganese (II) ion forms. When solid Manganese(II) arsenate was placed in a 2.00 M solution of ammonia, at equilibrium, 0.308 M of ammonia remains. If the Kf of tetraamminemanganese (II) ion is 250.0, Determine the Ksp of Manganese(II) arsenate Hint: You will have to figure out the Kspf of the overall chemical equation first, then solve for Ksp by using Kf and Kspfarrow_forwardNeed assistance with the following chemistry problem.
