An ideal gas enters a valve at 500K and 3MPa at a steady state rate of 3 mol/min it is throttled to 0.5 MPa. What is the rate of entropy genration? Is the process reversible?
Use bond energy values to estimate the reaction enthalpy for the formation of ammonia from nitrogen gas and hydrogen gas. Note that N2 contains a triple bond. You will need structural formula.
The endpoint in the titration is "overshot" A. is the reported molar concentration of the hydrochloric acid solution too high or too low. B. As a result of this poor titration technique, is the reported number of moles of B4O5(OH)4^2 would be too ..
When 0.0172 mol HI is heated to 500 K in a 2 L sealed container, the resulting equilibrium mixture contains 1.9 g of HI. Calculate Kc for the decomposition reaction 2HI(g) *) H2(g) + I2(g) .
consider the constitutional isomers 2-methyl-1-butene 2-methyl-2-butene and 3-methyl-1-butene. when each of these
Ethanethiol is more soluble in water because sulfer has agreater electronegativity value than oxygen. Ethanethiol is more soluble in water because it has a lower molecular mass than 1-propanol.

Calculate the quantity of work associated with the compression of gas from 5.60 L to 3.40 L at a constant pressure of 1.23 atm.
A student mixed 50.0 mL of 0.50 M H2SO4 (aq) at 18.5 degrees C with 100 mL of 0.50 M NaOH (aq) at the same temperature. After the reaction was completed, the temperature rose to 22.0 degrees C. What was the heat of reaction? (Assuming the densitie..
During a lab experiment, we were to determine the relative level of saturation by adding, drop by drop, a solution of bromine in cyclohexane to oil and a fat, individually. However, the color that is supposed to be retained due to unreacted bromin..
