The molecular weight of Cr(CO)6 is 220 g/mol. When 2.20 grams of Cr(CO)6 reacts according to the following equation at 400 °K in a closed system the temperature goes down and 5.2 kJ of hear is absorbed: Cr(CO)6(solid) -> Cr(solid) + 6 CO(gas). Calculate ?E° and ?H° for this reaction.
Why is sulfuric acid, rather than hydrochloric acid, used to catalyze the dehydration of alcohols?2. A sample of 150 mg of an organic compound is dissolved in 7.5 ml of water. The solution is paced in a 20-cm polarimeter tube and the rotation meas..
A sample of He gas (V = 3.0 L) at 5.6 atm and 25 °C was combined with 4.5 L of Ne gas at 3.6 atm and 25 °C in a 9.0 L flask (which was initially evacuated).
Consider the solution reaction AlCl3 + 3AgNO3 -> 3AgCl + Al(NO3)3. What volume of 0.100 M AlCl3 will exactly react with 55.0 mL of 0.162 M AgNO3?
Complete the following equations in molecular form. The reactant coefficients are correct. Indicate precipitation, redox, or acid – base. Write the equations in NET ionic form (no spectator s). Balance charges and use the correct suffixes.
What complementary functional group would need to be present in the neuraminidase active site for (a) hydrogen bonding and (b) ionic interactions to oseltamivir to be observed?
What mass of natural gas (CH4) must burn to emit 470. kJ of heat? CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g).
63.0 mL of a 1.20 M solution is diluted to a volume of 208 mL. A 104-mL portion of that solution is diluted using 157 mL of water. What is the final concentration.
A 347 ml sample of solution contains 5.1 g of CaCl2. Calculate the molar concentration of chloride ion in this solution
How much water must be added to 562 mL of 0.200 M HCl to produce a 0.148 M solution? (Assume that the volumes are additive.)
What is the equilibrium concentration of hydronium ion in a solution that is 0.041 M in HF and 0.19 M in F1- ion.
Alkynes can be hydrated in the presence of acid and HgSO4, by electrophilic addition of a molecule of water to the triple bond. The reaction proceeds by way of a carbocation intermediate
Assume a wind turbine with a hub 50 meters above the ground, a rotor diameter of 60 meters and a wind-conversion efficiency of 25 percent. The turbine operates in an area with an average wind-power density of 700 watts/sq meter at 50 meters altitude.
