The specific rate constant for the decomposition of NO2 is 0.755 M-1s-1 at 330 degrees Celsius as well as 4.02 M-1s-1 at 378 degrees Celsius. Explain what is the activation energy for the reaction?
The unbalanced equation for the reaction is... BrO3^-(aq) + Sb^3+ (aq) ---> Br^-(aq) + Sb^5+ (aq) Calculate the amount of antimony in the sample and it percentage in ore.
Titanium is a strong, lightweight, corrosion-resistant metal that is used in rockets, jet engines, and bicycle grams. It is prepared by the reaction of titanium (IV) chloride with molten magnesium between 950 and 1150 degrees C via the following r..
It required 71.5 mL of a 0.155 M KNO3 solution to fully react the copper in the ore sample. What was the percent copper in the ore.
In going from room temperature (25.0 °C) to 10 °C above room temperature, the rate of a reaction doubles. Calculate the activation energy for the reaction.
The rate law for the reaction, 2NO(g) + O2(g) 2NO2(g), is found to be: rate of reaction = k [?NO]2?[O2?]2. The first, fast step is 2NO(g) N2O2 (g)
a compound having an approximate molar mass of 120-15 g has the following percent composition bymass carbon 38.44
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..
titanium metal has a body-centered circle unit cell. The density of titanium is 4.50 g/cm^3 . Calculate the edge length of the unit cell and a value for the atomic radius of titanium.
The C-C bond in this structure should become the C2-C3 bond in (2R,3S)-2-bromo-3-phenylpentane. Type the name of an atom or group to add to the structure, or press the atom's button. Click on an H atom to replace that H atom with the atom or group..
Two acid-base reactions are given below. Of the three reaction arrows presented in each reaction, select the arrow (via the multiple choice circle before it) that best indicates the acid-base equilibrium position
describe the nature and characteristics of pcbs. why are they of importance to an ehamps or fs professional who
If we assume that the volume change is due entirely to the density change (that is, neglect thermal expansion of the ice/water), what is the difference between the enthalpy change and the energy change during the process? Is this a significant dif..
