(a)
Interpretation:
Among the elements represented by sphere [1], [2] and [3] of the same period, the element with highest
Concept Introduction:
The elements are organized in periodic table on the basis of their electronic configuration. They are put in different groups and periods according to their atomic number. This makes the study of these compounds systematic as elements with same chemical properties fall in the same group.
(b)
Interpretation:
The given elements are represented by sphere [1], [2] and [3] of the same period, the element with largest ionization energy is to be identified.
Concept Introduction:
The elements are organized in periodic table on the basis of their electronic configuration. They are put in different groups and periods according to their atomic number. This makes the study of these compounds systematic as elements with same chemical properties fall in the same group.
(c)
Interpretation:
Among the three elements are represented by sphere [1], [2] and [3] of the same period, the element which gives up electron easily, is to be identified
Concept Introduction:
The elements are organized in periodic table on the basis of their electronic configuration. They are put in different groups and periods according to their atomic number. This makes the study of these compounds systematic as elements with same chemical properties fall in the same group.

- Provide the IUPAC name of the following molecule. Don't forget to include the proper stereochemistry where appropriate.arrow_forward3. 2. 1. On the graph below, plot the volume of rain in milliliters versus its height in centimeters for the 400 mL beaker. Draw a straight line through the points and label it "400 mL beaker." Volume (mL) 400 350 300 250 200 150 750 mL Florence Volume Versus Height of Water 400 mL beaker 100 50 0 0 2 3 4 5 Height (cm) 6 7 8 9 10 Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know? (see page 276 text) the design of the beaker is a uniform cylinder the volume of liquid increases evenly with its height resulting in a linear relationship. What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the graph to assist you in answering the question. 4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a best-fit curve through the points and label it "250 mL Florence flask." oke camearrow_forwardShow work. Don't give Ai generated solutionarrow_forward
- In 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. Mass of added solute (g) 0.255 C. Calculations 1. k; for cyclohexane (°C⚫ kg/mol) 20.0 2. Freezing point change, AT, (°C) 3.04 Part C.6 3. Mass of cyclohexane in solution (kg) 4. Moles of solute, total (mol) Show calculation. 5. Mass of solute in solution, total (g) 6. Molar mass of solute (g/mol) Show calculation.arrow_forwardDraw and name the R groups of all 20 amino acids.arrow_forward
