How do you find the mass of an unknown acid in a 10mL portion used for titration if my original mass of the unknown acid is 0.307g and was in a 100mL volumetric flask
A 100.-L flask contains a mixture of methane, CH4, and argon at 25C. The mass of argon present is 228 g and the mole fraction of methane in the mixture is 0.650. Calculate the total kinetic energy of the gaseous mixture.
It is possible to determine the ionization energy for hydrogen using the Bohr equation. Calculate the ionization energy for an atom of hydrogen, making the assumption that ionization is the transition from n=1 to n=∞.
Phosphorus-32 has a half-life of 14.0 days. Starting with 8.00 g of Phosphorus-32 , how many grams of P-32 will remain after 98.0 days?
What is the Volume of 0.8 mol of Benzene (C6H6) at 20.7 degrees C. The density of Benzene is 0.879 g/mL
Using the Boltzmann distribution given below, determine Jmax (quantum number of the most intensely populated rotational state) as a function of temperature. Then find Jmax for CN+ at 298 K and 1100 K.
The experiment all you observed rate law is rate =k [NO]^2 [Br2]. Show this mechanism is valid by deriving the rate law expression and showing that it is equal to the experimentally observed rate law
How much heat in kJ is absorbed when 63.7 g H2O at 100C is converted to steam at 100C?
Graphite is a semi-metal composed of sheets of fused benzene rings. There are no bonds between sheets, only van der Waals interactions
Calculate the wavelength () of the light in nanometers () corresponding to the energy change () value of this transition. You can use the following values for your calculations
