You take stoichiometric amounts of 2-heptene, C7H14, and oxygen in a sealed 1.500 L flask and allow them to react. The reaction goes to completion. The pressure in the flask after the reaction is measured and found to be 28.476861 atm at 297.15 K. The vapor pressure of water at this temp is 22.4 torr. How many grams of each product were formed and how many grams of 2-heptene and oxygen did you start? R= 0.0820578 L*atm/K*mol.
Consider the autodissociation of water as the behavior of an Arrhenius acid. Use this to explain the temperature dependence of the autoionization of water and use it to explain
Calculate the heat required to raise the temperature of 125 g of water are heated from 20.0oC to 100oC based on a specific heat of water of 4.184 J/g oC.
26.0cm of a solution containinh 1.86g of X2CO3 in 250 reacted completely with 27.0cm of solution contain 3.65g of HCL per dm,calculate the molar mass of X2CO3 and relative atomic mass of X, and identify X.
Hydrogen sulfide decomposes according to the following reaction, for which Kc = 9.30 10-8 at 700°C. 2 H2S(g) 2 H2(g) + S2(g) If 0.33 mol H2S is placed in a 4.7 L container
A solution is prepared with initial concentrations of .038 M AL^3+ and .29 M NaF. If the Kf for AlF6^3- is 7.0 * 10^19, what is the concentration of Al^3+ (aq) at equilibrium?
On a cold dry morning after a frost, the temperature was -5C and the partial pressure of water in the atmosphere fell to .30 kPa. Will the frost sublime? What partial pressure of water would ensure that the frost remained?
A sample of gas is compressed from 13.01 L to 4.27 L using a constant external pressure of 3.63 atm. At the same time, 1,453 J of heat flows into the surroundings. What is the internal energy change for the gas
if the level of solution in the column drops below the level of the resin, channels will be formed in the resin column.How will this influence the efficiency of ion exchange in the column?
how many grams of potassium permanagate are needed to discolor 1 gram of 2-pentene in basic solution.
The base peak in the mass spectrum for this compound indicated the compound lost a fragment that has an m/z=17. This fragmentation corresponds to the loss of a(n)
All of the potassium reacted to produce bubbles of hydrogen gas, which, because of the extraordinary care that was taken, did not ignite. How much hydrogen gas was produced, in units of moles?
observed that 7.48 mmol of baf2 will dissolve in 1.0L of water. use these data to calculate the value of Ksp for barium fluoride
