Provide complete solutions in a separate sheet.) steps involved in the extraction of magnesium from seawater in the dow process, starting as mg(oh): using quicklime (cao), until the electrolysis of molten (a) describe from the precipitation of mg mgcl, to produce magnesium metal. provide a relevant balanced equation for cach step. b) if the concentration of mg " in seawater is 0.055 m, how many kilograms of calcium oxide, cao., are required to precipitate all of mg as mg(oh): in 1.00 x 10 gallons of seawater? (c) how many grams of magnesium m entire dow process has a net yield of 91.0%? d) the final step in the dow process involves electrolysis of molten mgcl2 to produce mg and cl. how many kilograms of magnesium can produced in 1.00 hour if the electrolytic cells deliver a constant current of 1.0 x 10 a? (e) name two major industrial uses of magnesium metal.

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

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
