What are the three types of spectra? Correct Answer-Continuous, emission, and absorption spectra What creates a continuous spectrum and what does it look like? Correct Answer-A hot solid, such as a star. All of the color is shown on the spectrum. There are no breaks. What creates an emission line spectrum and what does it look like? Correct Answer-A hot gas, such as a nebula. Only breaks in color are shown. What creates an absorption spectrum and what does it look like? Correct An...

D. To increase the absorption in the solutions -Answer-A. To enable the comparison of the absorption spectra, absorbed radiation is due only to if glucose is in the blood and not due to the difference in the absorption features of the walls What is the approximate energy of a photon in the absorbed radiation that yielded the data in Table 1? (Note: Use 1 eV = 1.6 × 10-19 J and hc = 19.8 × 10-2

holminum oxide correct answers best suited for verifying wavelength dispersion from 2nd order spectra correct answers most common cause of stray light, causes loss of linearity at high-analyte concentration glycolysis correct answers the conversion of glucose or other hexoses into lactate or pyruvate heparin tube correct answers tube used for blood gas absorbance correct answers proportional to the inverse log of transmittance. directly proportional to concentration spectrophotome...

What is a photomultiplier? - A vacuum tube consisting of a photoemissive cathode, a series of intermediate electrodes called dynodes, and a collection anode. What does a single-beam spectrophotometer do? - A single-beam spectrophotometer employs one beam of radiation that irradiates one cell. What happens in a deuterium lamp? - The lamp energy from the power source produces an excited deuterium molecule that dissociates into two atoms in the ground state and a photon and the energies of th...

A crescent moon is visible in the northern hemisphere, with the crescent shape on the right side of the Moon. This phase is called: - ️️Waxing crescent A lens ___ light to converge at a point - ️️Refracts A magnetic field line pokes through the Sun's photosphere inhibiting convection and cooling that location. What feature is observed in that location on the photosphere? (Also describe how the other features are formed) - ️️Sunspot A mirror ___ light to converge - ️️Reflects ...

AAMC Exam 4 FL Review Questions and Answers Limestone does NOT decompose when heated to 900 K because, at 900 K, ΔH is: A. positive and less than TΔS. B. positive and greater than TΔS. C. negative and less than TΔS. D. negative and greater than TΔS. -Answer-B. positive and greater than TΔS., the reaction does not occur, ΔG = ΔH - TΔS > 0. From inspection of the reaction, it can be concluded that ΔS > 0 (a gas evolves). Consequently, ΔH > TΔS explains why the reac...
