State a balanced net ionic equation for the reaction that occurs between acetic acid as well as sodium hydroxide
In a titration expirement, if we were to replace KHP as the primary standard with CsHP, would the higher molecular weight of the new standard alter the molar ratio of the standardization of the Sodium Hydroxide titrant
Elemental analysis is performed on an organic liquid with a fishy odor. Vaporization of 275.0 mg of the compound in a 190-mL bulb at 110°C gives a pressure of 400.0 torr. What is the molar mass of this compound? Enter units.
Nitrogen dioxide is obtained in a cylinder, but exists in equilibrium with dinitrogen tetrooxide. A 5.00g sample of this mixture is transferred to a 0.5L flask at 298K.
suppose that the 0.00200 m feno33 and kscn solutions were only 0.00100 m. when mixed together as descripbed in the
A gaseous fuel mixture stored at 752 mmHg and 298 K contains only methane and propane . When 11.6L of this fuel mixture is burned, it produces 767kJ of heat methane : 890 kJ/mol propane : 2,220 kJ/mol
In the double stranded helix structure of DNA, which bases are always hydrogen bonded to the following: cytosine, thymine, adenine, and guanine
In what direction do the functions point? What orbitals are"left" unused on the C atom?
A swimming pool is 27.31 yards long and 37.55 feet wide. The pool is filled with water from a hose that has a flow rate of 2.837 gallons/second. How many minutes will it take to fill the pool to a depth of 5.004 feet
What would be the pH of a solution prepared by combining equal quantities of NaH2PO4 and Na2HPO4? Explain. 2. Sufficient strong acid is added to a solution containing
Compound X, C14H12Br2, is optically inactive. On treatment with strong base, X gives hydrocarbon Y, C14H10. Compound Y absorbs 2 equivalents of hydrogen when reduced over a palladium catalyst to give Z
Find the partial pressure of each produce and the total pressure in the flask at the end of the reaction.
Delta H of combustion of benzoic acid is 3.22 x e3 kJ/mol. 0.5 g of benzoic acid was burned in a calorimeter containing 1000.0 g of water. The change in temperature of the calorimeter was 3 degrees C. Calculate the heat capacity of the calorimeter..
