Give the products (if any) expected from the treatment of 2-methyl-2-pentene with ozone followed by aqueous hydrogen peroxide. Do not draw any byproducts.
A solution of H2SO4 and KI is then added to conver the MnO2 to MN^2+, and the iodide is converted to I2. The I2 is then titrated with standardized Na2S2O3. Calculate the amount of O2 in 25.0mL of water if the titration requires 2.45ml of 0.0112 M N..
The combustion of one mole of ethanol (C2H5OH(l)) to produce carbon dioxide and gaseous water has ?Hr = -1235 kJ · mol-1 at 298 K. What is the change in internal energy for this reaction?
How many moles of gas are present when you collect 35.83 mL of the gas over water at 25.3?C and 0.97 atm?
Calculate the molar solubility of AgI in 3.6 M NH3. The overall formation constant for Ag(NH3)2+ is 1.7 x 10^7.
A perfect sphere of aluminum metal with a diameter of 4.56x10^-2 m reacts with 3.80L of 5.25M hydrochloric acid. the products are an aluminum chloride solution and hydrogen gas.
When a sample of 5.00-g rams of Potassium thiocyanate is dissolved in H2O in a calorimeter that has a total heat capacity =6.225 kJ•K-1, the temperature decreases by 0.200 Kelvin. compute the molar heat of solution of Potassium thiocyanate.
identify a chemical reagent used in this experiment that can be used to distinguish cacl2 (soluble) from CaCo3 (insoluble)
Assuming that the total pressure of the gases is 1.52 and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure (in atmospheres) of each gas.
Calculate the pH at the equivalence point for the titration of 0.200 M methylamine (CH3NH2) with 0.200 M HCl.
The freezing point of t-butanol is 25.50°C and Kf is 9.1°C·kg/mol. Usually t-butanol absorbs water on exposure to air. If the freezing point of a 12.0 g sample of t-butanol is 24.59°C, how many grams of water are present in the sample?
