How much heat is produced when 1.25 g of chromium metal reacts with oxygen gas under standard conditions?
Determine the molecular formula of a compound, which has CF2 as an empirical formula if 1.55 g of this compound occupies 0.174 L at standard temperature and pre
The solubility of N2 in blood can be a serious problem (the "bends") for divers breathing compressed air (78% N2 by volume) at depths greater than 50 ft. Find the volume (in mL) of N2, measured at 25degrees celsius and 1.00 atm, released per liter..
Explain how do you calculate the photon wavelength (in nm) corresponding to the electron affinity for chlorine
You then tore off the corner, inserted filter paper in the funnel, and filtered your BaSO4 precipitate. How does this affect the percent sulfate you calculated; too low, too high, no effect
Determine the pH of a solution that is 1.40% NaOH by mass. Assume that the solution has density of 1.01 g/mL.
What would you use to prepare a buffer system with a pH of around 4.2. What would you use to make a buffer with a pH of around 9.2? Describe the process you used to choose the correct buffer for each pH.
A reaction has activation energy of 125 kJ/mol. At 25 degrees Celsius the rate is 5.0E5 M/s. If the temperature is decreased to 0 degrees with all other things being the same then what is the rate of reaction
Rate data for an enzyme-catalyzed reaction and constructed a Lineweaver-Burk plot. The best-fit line had a slope of 2.3 minutes and a y-intercept of 4.7 x 10^4 min/M. Calculate Km and Vmax.
A solution is prepared by adding 0.900 g of solid \rm NaCl to 50.0 mL of 0.100 M \rm {CaCl_2}. What is the molarity of chloride ion in the final solution. Assume that the volume of the final solution is 50.0 mL.
You need to make 500 ml of 100 mM potassium phosphate buffer at pH 7.5. You have the stock solutions of KH2PO4 and K2HPO4 at 1M each. You will make the buffer by adding some of each of these stock solutions to water.
At its closest approach, Mars is 56 million km from Earth. how long would it take to send a radio message from a space probe of Mars to Earth when the planets are at this closest distance.
