The alkaline battery is the most common primary nonrechargeable battery nowadays. Its anode consists of powdered zinc metal mixed with gel that is in contact with concentrated KOH solution which is why it is called alkaline battery. The cathode is a mixture of MnO2(s) and graphite. The mixture is separated from the cathode by a porous fabric. The entire battery is placed in a sealed steel container to reduce concentrated KOH leakage. The cathode reaction is: 2MNO2(s) + 2H2O ) + 2e- 2MNO (OH(s) + 20H-(aq) Write the anode half-reaction.Determine the overall cell reaction. If the cell potential is 1.55 V at room temperature, what is the cathode reduction half- potential?

In nitryl chloride (NO2Cl), the chlorine atom and the two oxygen atoms are bonded to a central nitrogen atom, and all the atoms lie in a plane. Draw the two electron dot resonance forms that satisfy the octet rule and that together are consistent with the fact that the two nitrogen–oxygen bonds are equivalent.
Remdesivir is a broad-spectrum antiviral medication that is currently being used to treat Covid- 19. Remdesivir has this chemical formula: C27H35N6O3P. Since it is made up of nonmetals, Remdesivir is a molecular compound. Answer the following questions about samples of Remdesivir. 1. On the first day of treatment, a patient receives 200. mg of Remdesivir intravenously. Compute the number of molecules of Remdesivir that are delivered in this dose to the patient.
