An equilibrium mixture of the following reaction has [SO3] = 0.391 M, and [O2] = 0.125 M at 600 . What is the concentration of SO2, if the value of Kc at this temperature is Kc = 4.34?

2 SO2(g) + O2(g) ↔︎ 2 SO3(g)

Explain please

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

Which sample at stp has the same number of atoms as 18 liters of ne at stp

Use the half-reactions of the reaction au(oh)3 + hi -> au +i2 +h2o to answer the questions
