- For a molecule there are 3 energy levels A, B and C, where B is an intermediate energy level between A and C. The A → C transition occurs at 480 nm and the B → C transition occurs at 885 nm. Indicate the wavelength at which the A → B transition will occur.arrow_forwardFor a molecule there are three energy levels: A, B and C. If the transition A → B occurs at 1049 nm and the transition B → C occurs at 885 nm, we can say that the wavelength of the transition A → C will occur at approximately:a) 164 nm b) 1934 nm c) 480 nm d) 967 nmarrow_forward: Naming the Alkanes a) Write the IUPAC nomenclature of the compound below b) Draw 4-isopropyl-2,4,5-trimethylheptane, identify the primary, secondary, tertiary, and quaternary carbons. c) Rank pentane, neopentane and isopentane for boiling point. pentane: H3C-CH2-CH2-CH2-CH3 neopentane: CH3 H3C-C-CH3 isopentane: CH3 CH3 H3C-CH2-CH-CH3arrow_forward
- An essential part of the experimental design process is to select appropriate dependent and independent variables. True Falsearrow_forward10.00 g of Compound X with molecular formula C₂Hg are burned in a constant-pressure calorimeter containing 40.00 kg of water at 25 °C. The temperature of the water is observed to rise by 2.604 °C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) Calculate the standard heat of formation of Compound X at 25 °C. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.arrow_forwardneed help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).arrow_forward
