Match the effects on the concentration of SO3 gas when the following changes occur after initial equilibrium has been established in this system (N. C. = no change). 2SO2(g) + O2(g) 2SO3(g) + 46.8 kcal

pressure increases
(Choices are N. C., increase, and decrease)

increase [O2]
(Choices are N. C., increase, and decrease)

increase volume of chamber
(Choices are N. C., increase, and decrease)

adding a catalyst
(Choices are N. C., increase, and decrease)

raising the temperature
(Choices are N. C., increase, and decrease)

Iknow #2 is d. i just need to know why

What’s the percent by mass of carbon in c10h14n2

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
