I want to prepare an exploding ballon with a 1 L volume that will be filled with butane and oxygen gases (1 atm pressure). What volume of butane and oxygen should I use to get the maximum "bang?"
N2H4+3O2----2NO2+2H2O The limiting reagent is O2 how many kg of NO2 are produced from the reaction of 75kg of the limiting reagent.
Derive the activation energy for a reaction that proceeds 2 times faster when the temperature is raised from 20 C to 30 C.
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of Br- is doubled? Just put in the number as a whole number or fraction.
The increase in volume is due to the H2 gas created. 50 g of tin (Sn) is 0.421 moles. That is also the number of moles of H2 that are created. Use tha ideal gas law to compute the added volume due to that gas.
Gas chromatography. Answer the following questions about retention times of the following compounds. Given naphthalene (boiling point = 218 degrees C), phenol (boiling point =181.7 degrees
Write an equation for any changes observed.
Part A: Use Coulomb's law to calculate the ionization energy in kJ/mol of an atom composed of a proton and an electron separated by 221.00 pm. Part B: What wavelength of light would have sufficient energy to ionize the atom
Calculate the degree of dissociation (he fraction of molecules dissociated) for the acid in this solution. (You may assume that the mean ionic activity coefficient has a value of 1). (c) From the degree of dissociation, determine the acidity const..
Assume that the initial purple solution is 16.05mg/L in sodium salicylate, 0.15M in HCl and 0.065 M in iron(III) ions. What are the concentrations of these three once you diluted the 10.00 mL to a final volume of 50.00 mL in the volumetric flask
