Consider the reaction: H2(g) + CO2(g) ? H2O(g) + CO(g) is 4.2 at a 1650C. Initially 0.50 mol of H2 and .50 mol of CO2 are injected into a 5.0 L flask. Calculate the concentration of CO at equilibrium
mixture of the same bromoalkanes, and they both undergo hydroboration/oxidation to give a mixture of the same alcohols. Determine What is the structure of B?
what is the minimum amount of NaCl needed to get the 18.2 degrees? Its a molality equation
The gas and the liquid have specific heats of 117.2 J/mol K and 72.3 J/mol K. How much heat is evolved when 20.0 g of CCl2F2 is cooled from +40 C to -40 C?
Show whether or not precipitate will form in this process when the Ksp of Pbl = 9.8*10 -9
From the values of delta H and delta S, predict which of the following reactions would be spontaneous at 25*C:
A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL.
Consider a hypothetical reaction in which A and B are reactants and C and D are products. if 15grams of A completely reacts with 12grams of B to produce 14grams of C, how many grams of D will be produced.
consider the expansion of 1L of gas orginally at 9 atm pressure to 1 atm pressure. the T remains constant at 25*C. Defining the gas as the system, calculate the work done on the system when
A sample containing 4.80 g O2 of gas has a volume of 15.0 L. Pressure and temperature remain constant. What is the new voume if 0.500 mole O2 gas is added.
We can measure the concentration of HCl solution by reaction with pure sodium carbonate: 2H^+ +Na_2CO_3 -->2Na^+ +H_2O + CO_2. Complete reaction with 0.9674 + and - 0.0009g of Na_2CO_3 (FM 105.9884 + and - 0.0007) required 27.35 + and - 0.04 mL of..
