The density of a 0.0122 M KMnO4 is 1.037 g/mL. Suppose 26.35 g of 0.0122 M KMnO4 are required to titrate 1.072 g of a household H2O2 solution. Except for answers to (a) and (e), use scientific notation. Do not include units, just enter numerical v..
A student reacted 0.22 g of zinc (Zn) with excess hydrochloric acid (HCl) to generate hydrogen gas (H2).
In the electron transport chain, electrons from FADH2 are eventually used to reduce O2 into H2O. Experimentally, the proton motive force created by this process will generate 2 ATP molecules from ADP and Pi, using ATP synthase. From the informatio..
