Urea (NH2CONH2) an important nitrogen fertilizer is produced industrially by the reaction 2NH3(g)+CO2(g)--->NH2CONH2(aq) + H2O(l) given that ?G^degree = -13.6KJ, calculate
A solution containing Pt4+ is electrolyzed with a current of 5.00 A. How long will it take to plate out 77% of the platinum in 0.50 L of a 0.010 M solution of Pt4+?
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
What amount of energy is required to melt a 13.5 g piece of ice at 0oC to form liquid water at the same temperature of 0? The heat of fusion of water = 333 J/g , T he specific heat of H2O is approx. constant at 4.18 J/g x C.
Silver chloride, often used in silver plating, contains 75.27% Ag. Calculate the mass of silver chloride required to plate 225 mg of pure silver.
the gas sample weighs 2.62grams then computes the molecular weight and determines the identity of the gas.
Consider the equation A(aq) + 2B(aq) -> 3C(aq) + 2D(aq). In one experiment, 45.0 mL of 0.050 M A is mixed with 25.0 mL 0.100 M B. At equilibrium the concentration of C is 0.0410 M. Calculate K.
