Explain how a change in the amount of a product causes a shift in equilibrium?
what is the molarity of a sodium hydroxide solution if 34.85 mL of the soution neutralizes 1.883 grams of pure KHP?
The first-order rate constant for the decomposition of N2O5, 2N2O5 --> 4NO2 + O2 at 70 degrees C is 6.82 * 10 ^-3 . Suppose we start with 2.90×10?2 of in a volume of 1.7 L. A)
A technician would like to find the concentration of a NaOH solution using KHP as the primary standard. The reaction of NaOH and KHP is as followed:
A 1-L flask is filled with 1.10 g of argon at 25 C. A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm . What is the partial pressure of argon,PAr , in the flask?
the total pressure of the system is found to be 4.50 atm At 700 degrees celsius. compute the equilibrium partial pressures of carbon dioxide and carbon monoxide if the equilbrium constant Kp = 1.52,
What volume of 0.160 M of Li2S solution is required to completely react with 125 mL of 0.160 M of Co(NO3)2
Cyanogen is a gas which contains 46.2 % C and 53.8 % N by mass. At a temperature of 25oC and a pressure of 750 mmHg, 1.50 g of cyanogen occupies 0.714 L.
Calculate the molar mass of a gas that has a density of 0.232 g/L at 156 oC and 222 torr. Use R = 0.0821 L-atm/mol-K for the value of the gas constant.
identify the functional group; and 3) and discuss general key chemical properties of the chemical that a fire, environmental, health or safety personnel should know.
