What is the frequency of the light based on Optical fibers allow the fast transmission of vast amounts of data. In one type of fiber, the wavelength of transmitted light is 8200 nm?
Calculate the theoretical yield of ammonia produce by the reaction of 100 g of h2 gas and 200 g of n2 gas 3h2+n2=2nh3
Consider a galvanic cell in which Al3 is reduced to elemental aluminum, and magnesium metal is oxidized to Mg2 . Write the balanced half-cell reactions that take place at the cathode and at the anode.
Assuming 3.0% hydrogen peroxide by weight has a density of 1.00 g/mL, demonstrate that an excess of hydrogen peroxide was used in the oxidation step of Fe(II) to Fe(III). Think about redox balancing where you used half reactions to add up to get the final, overall reaction. What is the limiting reagent? The synthetic process […]
A student writes the following statements about the relationship between mass defect and nuclear binding energy. 1. When an isotope’s protons and neutrons come together to form a nuclide, a small amount of mass is converted to energy. 2. An equivalent amount of energy must be added to the nuclide to split apart its protons […]
