11. A 1M solution of SbCl, in organic solvent shows no noticeable reactivity at room temperature. The sample is heated to 200°C and the following equilibrium reaction is found to occur: SbCl, =SbCl, + C1,
The value of Keq at 200°C was measured to be 10^‐⁶. The reaction was then heated to 350°C, and the equilibrium concentration of Cl, was found to be 0.1 M, which of the following best approximated the value of Keq at 350°C?
(A) 1.5
(B) 1.0
(C) 0.1
(D) 0.01
(E) 0.001

When molecules of water vapor in the air come in contact with a cold can of soft drink , they lose energy ,slow down, and form a liquid due to decrease in ?

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
