(b)
Interpretation:
The formula for the ionic compound formed by Pb4+ with SO4-2 and name the compound needs to be determined.
Concept introduction:
When the number of electrons increases or decreases from the atomic number, ions are formed. Cation is a positively charged ion formed by losing electron/s and anion is a negatively charged ion formed by gaining electron/s. While writing name of the ionic compounds, the name of cation is always written first followed by the name of the anion. In order to form an ionic compound, the cation and anion combine in such a way that the total charge is zero.

- Show work. Don't give Ai generated solutionarrow_forwardIn the video, we looked at the absorbance of a certain substance and how it varies depending on what wavelength of light we are looking at. Below is a similar scan of a different substance. What color BEST describes how this substance will appear? Absorbance (AU) Violet Blue Green Orange 1.2 1.0- 0.8- 0.6- 0.4- 0.2 0.0 450 500 550 600 650 700 Wavelength (nm) violet indigo blue green yellow orange red Red O Cannot tell from this information In the above graph, what causes -450 nm wavelength of light to have a higher absorbance than light with a -550 nm wavelength? Check all that are true. The distance the light travels is different The different data points are for different substances The concentration is different at different times in the experiment Epsilon (molar absortivity) is different at different wavelengthsarrow_forward5. a. Data were collected for Trial 1 to determine the molar mass of a nonvolatile solid solute when dissolved in cyclo- hexane. Complete the table for the analysis (See Report Sheet). Record calculated values with the correct number of significant figures. B. Freezing Point of Cyclohexane plus Calculation Zone Unknown Solute 2. Mass of cyclohexane (g) 10.14 Part C.4 3.
