Use bond enthalpies to estimate the enthalpy change for the following gas-phase reaction:
CH4 + Cl2 --> CH2Cl2 + H2
Cd2 forms two complexes with C2H3O2, with the following formation constants:(a) Find K2 for the reaction, (b) You prepare 1.00 L of solution containing 0.110 mol CH3CO2Na and 4.00 × 10-4 mol Cd(ClO4)2. Compute the fraction of cadmium in the form ..
The Kp for the reaction is 4.3X10^-4 at 648K. Determine the equilibrium partial pressure of NH3 in a reaction vessel that initially contained 0.900atm N2 and 0.500 atm H2 at 648K.
caclculate the number of grams of Fe formed when 0.300kg of Fe2O3 reacts.
A sample of a gas at 0.91 atm occupies a volume of 374 mL. If the temperature remains constant, what will be the new pressure if the volume increases to 265 mL?
what volume of 420 ml of hydrogen occupy if the temperature is raised from 0 C to 95 C?
What is the molality of a solution prepared by dissolving 10.0 grams of methylamine, CH3NH2, in 50.0 mL of ethanol, C2H5OH?
An 18.0-g sample of magnesium is completely burned in the presence of air to form magnesium oxide. What is the mass of the magnesium oxide obtained?
Calcultate what is the value of enthalpy H reaction If the temperature increased from 35.0 degree celsius to 76 degree celsius and the heat capacity of the calorimeter = 23.3kj/c ? (the molar mass of C2H5OH = 46.07g/mol. )
To find the of X-281, you prepare a 0.086 test solution of X-281. The pH of the solution is determined to be 2.70. What is the of X-281
arrange the following in increasing order of mass.
A 10 mL sample of a solution of Pb(ClO3)2 was diluted with water to 21 mL. A 10 mL sample of the dilute solution was found to contain 0.021 moles of Pb2+. What was the concentration of Pb(ClO3)2 in the original undiluted solution?
