A student mixes two solutions: 10.0 mL of 0.0040 mol/L lead (II) nitrate, Pb(NO3)2 (aq), and 15.0 mL of 0.25 mol/L potassium chloride, KCl (aq). If the solubility product constant, Ksp, for lead (II) chloride, PbCl2, is 1.2 x 10-5 at 25° °
C, will a precipitate form when these two solutions are mixed? Why?

In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al

Why is permeable soil best for plants that need a lot of drainage?

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
