According to the textbook, "A recent area of research involves the development of paper-based measuring devices. For example, the nonprofit organization Diagnostics for All (DFA) based in Cambridge, Massachusetts, has invented a paper-based device to detect proper liver function. In this test, a drop of the patient's blood is placed on the paper, and the resulting color that develops can be used to determine whether the person's liver function is normal, worrisome, or requires immediate action. Because these paper-based devices are cheap, disposable, and easily transportable, they are especially useful in developing countries" (Zumdahl/DeCoste , 2019). In your initial post to the discussion, answer the following questions:
-Do scientists have a moral obligation to use chemistry for purposes like the one stated above? Why or why not?
-How else can chemistry be used to make a positive impact on the world?
-How might chemistry be misused to have a negative impact? What measures can scientists put in place to remove that threat?
Write the electron configuration for the first excited state for N2 -that is, the state with the highest-energy electron moved to the next available energy level. Is the nitrogen in its first excited state diamagnetic or paramagnetic?
Then 5.0mL was withdrawn and diluted to 200mL. The spectrum of this solution exhibited a maximum absorbance of 0.642 units at 554nm in a 2cm cell. The molecular absorbance , e, is 423 M-1cm-1. What is the mass of the analyte in grams

Name the compounds MnCl2, SCl2, and CaBr2. Explain the use or omissions of the Roman numeral (II) and the prefix di-.
the heat of combustion of c10h18 is -6286 kj/mol. the heat of combustion for c10h8 is -5157kj/mol.
Which method is best at transferring heat from the fluid to the eggshell? Compare the temperature gradients you observed in the two methods. Which of the methods produces the most pronounced gradient?
A silver block, initially at 56.2Celcius, is submerged into 100.0g of water at 25.2Celcius, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.5Celcius. What is the mass of the silver block
If the ka for the acid phenol (call it HP) is 1.3 x 10-10, what is the pka of the phenolate ion (P-)
determine the activation energy (in kJ/mol) for the reaction. Note that the reaction is "3/2" order in CH3CHO so k has the units of 1/M1/2 s. Strategy: consider the Arrhenius equation written as a linear equation.
