Explain when doing a recrystallization using a Buchner funnel, what happens to the impurities that are more soluble than your compound in the solvent used?
What is the pH of a solution that results from mixing together equal volumes of a 0.110 M solution of acetic acid and a 0.0550 M solution of sodium hydroxide
What is the concentration of an unknown water sample if the assumed resistance is 650ohms?
The stack gas contains C02 at a partial pressure of 80 mm Hg and no CO,O2, methane or ethane. Calculate the mole fraction of methane in the fuel and the dew point temperature of the stack gas.
Determine the boiling point of a solution that contains 78.8 g of naphthalene (C10H8) dissolved in 722 mL of benzene (d = 0.877 g/mL). Pure benzene has a boiling point of 80.1°C and a boiling point elevation constant of 2.53°C/m.
Briefly comment on the effect of solution concentration on cell potential. Note that E knot is measured using 1M solutions,
Nitrogen gas (N2) reacts with hydrogen gas (H2) to form ammonia (NH3). At 200°C in a closed container, 1.04 atm of nitrogen gas is mixed with 2.03 atm of hydrogen gas. At equilibrium the total pressure is 2.03 atm. Calculate the Kp value for this ..
This is a study guide for naming of organic compounds, specifically alkanes and substituted alkanes. Thirty (30) questions and answers are also included. The study guide shows you
Calculate the 'size' of a hydrogen atom in its ground state according to this definition. Go on to explore how the 'size' varies as the definition is changed to other precentages, and plot your conclusion.
for a certain gas-phase reaction the fraction of products in an equilibrium mixture is increases by increasing the
the reaction between c2h4 and hbr to form c2h5br is carried out in a continuous reactor. the product stream is analyzed
What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water. Enter your answer in kilojoules per mole of compound t..
The comple IrCl(PMe3)3 is square planar with iridium having coordination number 4. When this complex reacts with Cl2 , two six coordinate complexes are formed. P NMR suggest one P environment in one of these products and two P environments in the o..
