Environmental scientists can use a similar lab kit to test collected water samples from bodies of water. In lakes and streams, calcium carbonate (CaCO3) causes alkalinity,
which allows it to function as a buffer, neutralizing any acid rain that may enter the
water supply. A buffer is a substance that serves to resist small changes in acidity or
alkalinity in a solution.
Environmental scientists monitoring pollution levels are measuring buffer levels in
two specific lakes. They found that Lake B had a greater ppm of calcium carbonate
than Lake A.
Which of the two lakes would be able to neutralize a greater amount of acid rain?
Explain your answer.

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
