Which of the following is most likely NOT a chemical reaction? (A)
A white powder and a clear liquid mix and the beaker holding the mixture gets cool to the touch

(B)
A white solid and a clear liquid mix and produce a bright orange, bubbling substance

(C)
A pan containing a clear liquid is place on a hot stove and begins to bubble after a few minutes.

(D)
A blue liquid and a green solid mix and produce a purple paste

For the following, determine the type of reaction and then give products.

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

Can someone me with 3 and 4 plz. this is for masteries test.
