if 4.0g H2 react, how many grams of NH3 will be formed?
if this energy were used to vaporize water at100 degrees celcius how much water in liters could be vaporized?assume
Calculate the enthalpy change in kJ when 21.6g of H2S is burned. 2H2S(g) + 3O2(g) --> 2SO2(g) + 2H20(g) Change in H=-1036kJ/mol
Complete and balance the following equations, and identify the oxidizing and reducing agents. (Recall that O atoms in hydrogen peroxide, H2O2, have an atypical oxidation state.)
For a reaction of hydrogen with iodine, the rate constant is 2.45*10^-4 L mol-1 s-1 at 302 C and 0.950 L Mol-1 s-1 at 508 C.
What is the balanced equation for a reaction between potassium iodide and lead II chloride
Na3P + 3H2O ---> PH3 + 3NaOH. What is the theoretical yield of PH3 when 150 grams of Na3P is mixed with 250 grams of H2O? If the actual yield is 30 grams, what is the % yield?
Two vessels are labeled A and B. Vessel A contains NH3 gas at 70°C, and vessel B contains Xe gas at the same temperature. If the average kinetic energy of NH3 is 7.1 10-21 J/molecule, calculate the mean-square speed of Xe atoms in m2/s2.
a gas is heated from 255 k to 284 k while its volume is increased from 24.0 l to 32.0 l by moving a large piston within
Conclude the range of pressures that this system can exists as 2 phases By imagine Raoult's law is applied to the system
Diethyl ether have a vapor pressure of 401 mmHg torr at 18 0C and its molar heat of evaporation is 26.0 kJ/mol explain what is its vapor pressure at 32.00C ( R = 8.314J/K.mol)
Show all the steps in the mechanism for the following reaction, When benzene is mixed with deuterated sulfuric acid, deuterium is slowly incorporated onto the ring. Show the mechanism for this reaction and explain how this relates the sulfonation of ..
A primary sedimentation tank has 140 mg/L of BOD in its effluent. The effluent flows into an activated sludge process at a rate of 4.8 MGD. The treatment must reduce the BOD by 125 mg/L so that it can meet an effluent requirement of 15 mg/L. How m..
