The cell shown below has a measured cell potential of +0.06839 V at 25.0 °C. A graph of the cell potential as a function of temperature is linear in the temperature range 20 °C to 30 °C with a slope of +4.18x10 V-K.

Which statement about detecting temperature is TRUE?   Nociceptors detect small changes in temperature.   Your skin has an equal distribution of temperature receptors.   There are separate receptors for hot and cold.   There are over 20 types of temperature receptors.

student found a bottle of unknown origin in the basement of an "CAUTION—contains С₁H₁O.” No other A old house. The bottle was labelled information was given, but inside the bottle were some white crystals. The student took the bottle to a chemistry laboratory, where she analyzed the crystals with the help of the laboratory staff. C₁2H₁6O reacted with Br₂ in CCl4 adding one mole of Br, and forming C₁₂H₁OB2₂. When a sample of C₁₂H₂O was reacted with O3 followed by Zn/H₂O, two different samples, J and K, were obtained. Compound J had a molecular formula of C.HgO₂, and its NMR is shown below. Compound K had a molecular formula of C₂H₂O, and it could be oxidized to compound L, with a molecular formula of C₂H₂O₂. The IR spectrum of L showed a very wide, strong band centred around 3000 cm*¹. The NMR spectrum of L showed only two different absorptions: a doublet (6H) at 0.9 ppm and a septet (1H) at 3.6 ppm. There was also a singlet (1H) off the scale at 11.8 ppm. students, deduce possible…

Potentially Useful Information Spectrochemical Series: I < Br < SCN° < Cl° < NO3¯ < F < OH° < C2O4²-~ H2O < NCS < NH3 < en < PPH3 A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes. The coordination complex causing the orange solution causes a larger splitting between the d orbitals of the metal then the coordination complex causing the... O red solution. O yellow solution. What color light does the…
