In his explanation of the photoelectric effect, Einstein stated that the incident radiation had to have a minimum energy to dislodge the electron from the metal surface. This energy is called the work function. If the work function of tantalum (Ta) is 6.41 x 10-19 J, what is the longest wavelength of light that will eject an electron from Ta metal?
Students in the lab place some sodium chloride in the beaker and remassed it to obtain a mass of 73.25 grams using a digital balance. Find the mass of salt in the beaker.
The mass ratio of sodium to fluorine in sodium fluoride is 1.21:1. A sample of sodium fluoride produced 36.5 {rm g} of sodium upon decomposition. How much fluorine (in grams) was formed?
Rank the fluorine species from most to least stable. To rank items as equivalent, overlap them.
Doubling the distance between an individual and the source of radiation reduces the radiation exposure to one-fourth the original value.
What potential issues might arise if the pH of your buffer is too close to the pI of your protein of interest? Why might an extreme buffer pH ( 9) be unsuitable?
Instead of 6 M NaOH being added to the test solution, 6 M HCl is added. How will this affect the test for the presence of ammonium ion in the solution? Explain.
Iron is obtained commercially by the reaction of hematite (Fe2O3) with carbon monoxide. How many grams of iron is produced when 25 mol of hematite reacts with 30 mol of carbon monoxide? with the balanced equation of Fe2O3 + 3CO = 2Fe + 3CO2
when solid copper is added to nitric acid, copper nitrate, nitrogen dioxide, and water are produced. write the balanced chemical equation for the reaction list sis mole ratios for the reaction.
