Suppose that when you wake up in the morning, you are very hungry. you go to the refrigerator and remove an egg. on the way to the stove, you drop the egg on the floor and the egg breaks. you get a second egg from the refrigerator, break the egg shell, and drop the egg into the frying pan. you notice that some eggshell pieces have fallen into your egg, so you pick out the eggshell pieces by hand. you stir the egg to make a scrambled egg. you then turn on the stove and cook the egg. when cooked, you eat the egg. which of the italicized items are physical changes and which are chemical changes? tell whether the following are chemical or physical changes. 1- you drop the egg on the floor and the egg breaks 2- pick out the eggshell pieces by hand 3- stir the egg 4-cook the egg 5-eat the egg

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
