A student prepares phosphorous acid, H3PO3, by reacting solid phosphorus triiodide with water. PI3(s)+3H2O(l)H3PO3(s)+3HI(g) The student needs to obtain 0.250 L of H3PO3(d=1.651g/cm3). The procedure calls for a 45.0% excess of water and a yield of 75.0%. How much phosphorus triiodide should be weighed out? What volume of water (d=1.651g/cm3) should be used?
The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. 2. Suppose 53.0mL of dioxygen gas are produced by this reaction, at a temperature of 50.0°C and pressure of exactly 1atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.
Concrete is prepared by roasting the mineral calcium carbonate, CaCO3, to drive off CO2 and produce calcium oxide, CaO. The chemical equation for this reaction is: CaCO3 ==> CaO + CO2 The Grand Coulee Dam on the Columbia River in Washington State was built using a volume of concrete of approximately 1.0 x 107 m3. If concrete has a density of 2.4 x 103 kg/m3, and assuming concrete is 100% by volume CaO, how much CO2 was released producing the concrete used to build the dam?
Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq), as described by the chemical equation MnO2(s)+4HCl(aq)⟶MnCl2(aq)+2H2O(l)+Cl2(g) How much MnO2⁢(s) should be added to excess HCl(aq) to obtain 335 mL Cl2⁢(g) at 25 °C and 1.00×102 kPa ? mass: ______g MnO2
Assuming that gasoline is 100% isooctane and that the density of isooctane is 0.792 g/mL, what mass of CO2 (in kilograms) is produced each year by the annual U.S. gasoline consumption of 4.6 X 1010 L?
A mixture of methane (CH₄) and butane (C₄H₁₀) at one atmosphere pressure and 25°C has a density of 1.639 g/L. Assuming ideal behavior, what is the mass in grams of carbon that are in 1 liter of the mixture?
A website promoting the use of alternative energy vehicles and hybrid technologies claims that, "A typical automobile in the USA uses about 4040 gallons of gasoline every month, producing about 750 lbs of carbon dioxide." To determine the truth of this statement, calculate how many pounds of carbon dioxide are produced when 40.0040.00 gallons of gasoline are subjected to complete combustion. Assume that the primary ingredient in gasoline is octane, C8H18(l),C8H18(l), which has a density of 0.703 g/mL.
A saline solution used in intravenous drips for patients who cannot take oral fluids contains 0.92 (w/v) NaCl in water. What volume of the saline solution must be administered to the patient in order to deliver 7.7 g of NaCl?
Iron(III) chloride is used to treat drinking and waste water. It can be made by reacting iron with chlorine gas. Calculate the volume of chlorine gas (Cl2) STP that will react with 5.00 grams of iron
The physical fitness of athletes is measured by “VO2 max,”which is the maximum volume of oxygen consumed by anindividual during incremental exercise (for example, on atreadmill). An average male has a VO2 max of 45 mL O2>kgbody mass/min, but a world-class male athlete can have a VO2max reading of 88.0 mL O2>kg body mass/min. (a) Calculatethe volume of oxygen, in mL, consumed in 1 hr by an averageman who weighs 185 lbs and has a VO2 max reading of 47.5mL O2>kg body mass/min. (b) If this man lost 20 lb, exercised,and increased his VO2 max to 65.0 mL O2>kg body mass/min,how many mL of oxygen would he consume in 1 hr?
In 1897 the Swedish explorer Andreé tried to reach the North Pole in a balloon. The balloon was filled with hydrogen gas. The hydrogen gas was prepared from iron splints and diluted sulfuric acid. The reaction is Fe(s) + H2SO4(aq) -> FeSO4(aq) + H2(g) The volume of the balloon was 4400 m3 and the loss of hydrogen gas during filling was estimated at 10.%. What mass of iron splints and 98% (by mass) H2SO4 were needed to ensure the complete filling of the balloon? Assume a temperature of 0°C, a pressure of 1.0 atm during filling, and 100% yield. Mass of Fe = ______g Mass of H2SO4= ______g
