use the rock records on page 1 to complete the questions below.

1. examine record a. use the three basic rules to figure out the ages of the layers. in chart a, list the layers from youngest to oldest with the youngest layer in the first row.

2. look for signs of tilting, erosion, or folding. in the second column in chart a, write whether you think tilting, erosion, or folding took place. write tilting, erosion, or folding next to the letter of any rock layer that was formed when the tilting, erosion, or folding took place. if you see no evidence of tilting, erosion, or folding, write none.

3. repeat steps 1 and 2 for record b. record the data in chart b.

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
