Concept explainers
(a)
Interpretation:
Why the greater contribution, from the second of the two resonance structures shown, is counterintuitive based on charge stability is to be explained.
Concept introduction:
The relative stabilities of resonance structures can be determined on the basis of charge stability. The structure with positive charge on less electronegative atom and negative charge on more electronegative atom is more stable. The most stable resonance structure contributes more to the resonance hybrid.
(b)
Interpretation:
The greater contribution from the second resonance structure is to be explained.
Concept introduction:
The most stable resonance structure contributes most to the hybrid.
Stability of a resonance structure depends on a number of factors. More the number of bonds, more the number of atoms that follow the octet or the duet rule and less the number of formal charge, the more stable the structure.

- 4. Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forwardSteps and explanation pleasearrow_forward

Use the diffusion model from lecture that showed the likelihood of mixing occurring in a lattice model with eight lattice sites: Case Left Right A B C Permeable Barrier → and show that with 2V lattice sites on each side of the permeable barrier and a total of 2V white particles and 2V black particles, that perfect de-mixing (all one color on each side of the barrier) becomes increasingly unlikely as V increases.arrow_forward46. Consider an ideal gas that occupies 2.50 dm³ at a pressure of 3.00 bar. If the gas is compressed isothermally at a constant external pressure so that the final volume is 0.500 dm³, calculate the smallest value Rest can have.
