A 9.05 L container holds a mixture of 2 gasses at 29 degrees C the partial pressures of gas A and gas B respectively are 0.298 ATM and .702 atm if 0.130 mol a 3rd gas is added with no change in volume or temperature, what would the total pressure become?
At equilibrium the vessel is found to contain 0.566 g of H2. Calculate the equilibrium concentrations of H2, Br2, and HBr and Calculate Kc.
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
A 0.100 M solution of a weak acid, HX, has a pH of 2.110. What is the value of Ka for HX?
what volume of nitrogen gas is needed to react completely with 150.0 L of hydrogen in the production of ammonia.
A 771 mL gas sample at STP is compressed to a volume of 242 mL, and the temperature is increased to 31?C. What is the new pressure of the gas in Pa
The solution freezes at -0.085C. How many grams of urea were dissolved to make this solution? Please show work
the radiation level was determined to be .00935 microCi/mL. If 51Cr has t1/2=27.7 days, what is the volume of blood in the patient?
Assume that the density of the mixed solutions is 1.00 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g celcius), and that no heat is lost to the surroundings. The deltaHrxn for the neutralization of NaOH with H2SO4 is -114 kJ/mol ..
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
Identify the oxidation-reduction reactions among the following.
CS2(l) + 3 O2(g) -→ CO2(g) + 2 SO2(g) . If 1.18 mol of CS2 is combined with 1.55 mol of O2, identify the limiting reactant.
