Suna passes an electric current through a sample of clear, colorless, and odorless liquid. as the experiment continues, bubbles form, and the volume of liquid decreases. suna collects samples of two colorless, odorless gases that bubble out of the liquid. one of the gases burns. neither the original liquid nor the other gas burns.
which is the best explanation of her results?

a. the electric current changed some of the sample to gas even though the sample was not breaking down. therefore, the original liquid is a compound.

b. the electric current released a gas that was odorless and colorless, like the original sample. therefore, the original liquid is an element.

c. the sample was broken down by the electric current and formed a new substance that could burn. therefore, the original liquid is a compound.

d. the sample lost some of its volume, but the gas still had the same chemical makeup as the original sample. therefore, the original liquid is an element.

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
