The world record for the 100 meter dash is 9.58 s. The world record for the marathon (26.2 miles) is 2:03:38 (hrs:min:s). Assuming constant velocities, calculate the corresponding wavelengths for each runner (be sure to label which is which).
Assuming the solution has a heat capacity of 4.18 J/°C · g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
what volume of air is needed to burn it completely? Assume that the temperature of the burner is 195.0 Celcius, the pressure is 1.1 atmosphere, and the mole fraction of O2 in air is 0.21.
nitric acid will give a better yield than acetic acid because with acetic acid some material is converted into benzaldehyde by cleavage of the bond between two oxidized carbon atoms that is activated by both phenyl groups. Any help would be apprec..
A 4.50-g sample of liquid water at 25.0 C is heated by the addition of 133 J of energy. The final temperature of the water is __________ °C. The specific heat capacity of liquid water is 4.18 J/gK.
Rutherford fired positively charged particles at metal foil and concluded that most of the mass of an atom was..a) in the electrons.
Given that the atomic mass of carbon is given as 12.0107 g/mol, what are the approximate relative abundances of the two isotopes 12C and 13C?
the reactants in a Diels-Alder reaction are used in a 1:1 ratio. In this experiment, one reagent is used in excess. Which reagent is in excess, and why is it important that so much of it be used?
a student performs two melting-point determinations on a crystalline product. in one determination, the capillary tube contains a sample about 1-2 mm in height and the melting range is found to be 141 degree - 142 degree celsius
You use 27.5 mL of NaOH to titrate 100.0 mL of HCl and 18.4 mL of NaOH to titrate 50.0 mL of 0.0782 M H2SO4. What are the concentrations of the HCl and NaOH respectively?
