Calculate the amount of heat(in kj) required to convert 94.6g of water to steam at 100 degrees celsius. (the molar heat of vaporization of water is 40.79 kj/mol)
Magnesium oxide (MgO) has the rock salt crystal structure and a density of 3.58 g/cm3. Determine the unit cell edge length.
The specific heat of liquid water is 4.184 J/g. degree C. Calculate the energy required to heat 10.0 g of water from 26.5 degree C to 83.7 degree C.
In an actual experiment, 100 g each of copper and nitric acid are used and 70g of copper(II) nitrate is obtained. In this experiment, what is a) the limiting reactant
The complex ion [Co(CN)3]^3- absorbs a photon of wavelength 2.90×10^2 nm. What is the splitting energy of this complex in kJ/mol?
What is the wavelength of light whose energy is 1000.4 J?
Using A flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol.
Given that translational and rotational degrees of freedom typically behave classically, but vibrations behave quantum mechanically, the total (avg) energy of a diatomic is predicted to be U= (5/2)RT+ , where is obtained from Eq.124.
calculate the pressure exerted in the closed end of an apparatus if the atmospheric pressure is 720.0 torr and the height of the water column is 22.3 cm.
How much water must be added to 488 mL of 0.223 M HCl to produce a 0.134 M solution?
It is important to allow each spot added to the chromatography paper to dry completely before adding another spot.
Based on the stoichiometry, at what point does the limiting reactant change? show calculations to support your answer. The volume of acid HCL (10mL) is constant and mass of metal Mg (0.250g) is constant.
A pure fluid is described by the following expression for Gibbs free energy: G = gamma(T) + RTlnP, where gamma(T) is a substance specific function of temperature.
