The rate constant of the reaction A ? B + C is 2.75 x 10-7 s-1 at a certain temperature. The initial [A] is 2.19 M. How many days would pass before A had decomposed to the extent that 0.601 M of A remained?
Calculate the equilibrium concentrations if the initial concentrations are 2.31M N2 and 0.54M O2. (This N2/O2 concentration ratio is the ratio found in air.)
calculate the mass of ammonium nitrate that should be heated to obtain 100 mL of dinitrogen oxide, N2O, at 1.00 atm and 25 degrees celcius?
Showing only Valence electrons, write an equation for the reaction that occurs between sodium, Na
That would mean it wouldn't have any electrons to give. Can anyone answer this for me as to why there are 28 electrons being transferred if hydrogen has a oxidation state of +1 meaning it doesn't have any electrons to give?
Thiobacillus thiooxidans plays an important role in the sulfur cycle in nature. The organism oxidizes inorganic sulfur compounds, and in the process, obtains energy for the synthesis of ATP. The oxidation of sulfite to sulfate:
What is the freezing point of water under a pressure of MPa? Assume that the density of ice is 0.915 g.cm^-3 and that of liquid water is 0.998 g cm^-3 at this pressure
Give the number of valence electrons of each element and draw the Lewis structure for each molecule.
The molar heat of neutralization from hydrochloric acid and sodium hydroxide is -57.3 kJ/mol. use this accepted value to predict the heat evolved
The empirical formula for acetic acid is CH2O. Its molar mass is 60 g/mol. what the molecular formula is?
To determine the molar mass of an unknown protein, 1.00 mg was dissolved in 1.00 mL of water. At 25.0°C the osmotic pressure of this solution was found to be 1.47 × 10-3 atm.
How would I list the following aldehydes in terms of increasing reactivity ClCH2CHO, CH3CHO, Cl3CCHO, and Cl2CHCHO?
A student was using the concentrations of pipet calibration data listed in the Background Information for the determination of ka or propionic acid. Explain the problem the student encountered when preparing the following equilibrium mixture.
