Read Chapter 1 - Section 3 (Pages 12-16) and answer the following questions. (Feel free outline the section also, but you do not need to because we will define the key terms for
on Thursday/Friday and much of this section should be review material from previous scie
classes).

Modified Section 3 Review (Page 16)
1) (a) Describe the scientific process/method (pictured above). The scientific
method/process doesn't always follow the same steps in a set order. (b) Explain
why there is this variety:

Which other elements contain the same number of outer electrons as sodium

How many moles of carbon dioxide will form if 2.5 moles of c3h8 is burned

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
