A first order reaction has activation energy of 50.1 kJ/mol as well as a frequency factor Arrhenius constant of 8.27 x 1010 sec -1. Compute the rate constant at 26oC. Utilize the nearest whole number.
What is the heat absorbtion for 100 g liquid water that is frozen to ice at 0 degrees C and 1 atm
As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 35.0 atat was the volume of the sample. Assume that the temperature was held constant.
A white precipitate formed when the barium hydroxide solution was mixed with the sulphuric acid. *Mass of filter paper=0.96g *Mass of filter paper and precipitate=5.25g
An isolated chamber with rigid walls is divided into two equal compartments, one containing gas and the other evacuated. The partition between the compartments ruptures.
Use the reactions below and their equilibrium constants to predict the equilibrium constant for the reaction, 2A(s) 3D(g). 2A(s) 1/2B(g) + C(g) K1 = 0.0334
ammonia undergoes autoionization by the transfer of a proton: 2NH3 NH4+ + NH2-, K = 1×10^-33 at -50°C Since ammonia is better proton acceptor than water, the ionization of acids is relatively enhanced in liquid ammonia. For example, acetic acid i..
what is the volume of the hydrogen gas (at25oC and 100KPA) needed to produce 51.1g of ammonia?
Carbon and silicon belong to the same group and are known to have similar properties
equal quantites of the hypothetical strong acid hx weak acid ha and weak base bz are added to seperate beakers of water
a temperature of 37 degrees Celcius were heated to a temperature of 250 degrees Celcius. If the volume does not change, what is the new pressure of the gas in atmospheres?
reaction vessel initially contains 153 torr of water at 700.0 {\rm K} in contact with excess solid carbon, find the percent by mass of hydrogen gas of the gaseous reaction mixture at equilibrium.
Why is the difference in names between HCN,hydrogen cyanide and KH,potassium hydride
