Explain when a 1.150 g sample of iron ore is treated with 50.0 ml of HCL the iron dissolves in the acid to form a solution of FeCl3. The FeCl3 solution is diluted to 100.0 ml as well as the concentration of Fe3+ ions is determined by spectrometry to be 0.095 mol*L^-1. Mass% of iron in the ore?
What is the half-life of a compound if 85 percent of a given sample of the compound decomposes in 45 min? Assume first-order kinetics.
The flask is not only completely filled with vapor, but some liquid also remains in the bottom of the flask when it is removed from the hot water bath and cooled in part B3. How will this oversight affect the reported molar mass of the liquid.
assume that the kinetic energy of a 1500 kg car moving at 150 kmh could be converted entirely into heat. what amount of
Oxygen has three naturally occurring isotopes (o-16,o -17, and o-18). The mass and natural abundance of o -16 are 15.9949amu and 99.76% , respectively. The mass and natural abundance of o-17 are 16.9991amu and 0.038% , respectively.
Ammonium carbamate can dissociate into gases at 25 C according to the reaction: NH2COONH4(s) 2NH3(g) + CO2(g) If sufficient ammonium carbamate is sealed in a flask, the total pressure will be 0.117 atm at equilibrium. What is the value of Kp at ..
water to form dissolved boric acid, H3BO3, and hydrogen sulfide gas. What is the balanced Equation?
the initial rate is 0.03 mol L-1 s-1 when the initial concentrations are: [?NH?_4^+ ]_0 = 0.015 mol L-1 and [?NO?_2^- ]_0 = 0.02 mol L-1. What will be the initial rate (in mol L-1 s-1) when the initial concentrations are- [?NH?_4^+ ]_0 = 0.03 mol ..
A waste containing 10,000 mg/L sulfuric acid is neutralized by the addition of concentrated lime slurry [Ca(OH)2]. If the water temperature is 15 degrees Celsius before neutralization, what is the temperature after neutralization
To resolve an object in an electron microscope the wavelength of the electrons must be close to the diameter of the object. What kinetic energy must the electrons have in order to resolve a protein molecule that is 2.60 nm in diameter
