Explain why the form of the equilibrium constant for a chemical transformation can be predicted from its stoichiometric coefficients whereas the rate law must be determined experimentally.
Carbon monixide reacts with steam to produce carbon dioxide and hydrogen. At 700 k the equilibrium constant is 5.10. calculate the equilibrium concentrations of all species if 1.000 mol of each component is mixed in a 1.000-L flask.
An isotonic solution is described as 0.92% NaCl (g/mL). Would this also be the required concentration for isotonic solutions of other salts, such as KCl, MgCl2,
What are the molality and mole fraction of solute in a 34.0 percent by mass aqueous solution of formic acid (CH3OH)?
Since there are that many Moles of KOH there must be equal moles of the acid. So 4.14*10-3moles/.05L= X M of initial acid== .0828M?
performed using 1.8912g of zinc and 1.5965g of iodine. Determine the limiting reactant and calculate the theoretical yield of zinc iodine in grams.
A 10.0 balloon contains gas at a pressure of 640 torr. What is the new pressure of the gas at the 22.0 liters volumes if there is no change in temperature.
Identify three radioactive elements or reactions of different types and write the nuclear reaction for each element.
Suppose a reversible heat pump transfers heat from the outdoors at 0 degrees C to a room at 20 degrees Celsius. For each Joule of work input to the heat pump, how much heat will be deposited in the room?
Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the reaction:
Consider the following reaction: NH4HS(s) NH3(g) + H2S(g) An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]=.278M and [H2S]=.355M.
Excitation of the 3s electron from Mg+ to a 3p orbital occurs at 280.0 nm. The probability of filling a 3p orbital relative to the 3s orbital is 3/1. Assuming that the total Mg+ population in a given atomization source is 3.5 x 10^18 ions at any g..
