- 109 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what volume of CO2 is evolved during the process. What would have to be measured to predict the needed volume in advance?arrow_forwardSulfur-containing compounds give skunks their potent smell. One of the principal smelly compounds in skunk spray is (E)-2-butene-1-thiol, C4H7S. a What is the root-mean-square (rms) molecular speed of a gas molecule of this compound at 25C? b Using the value from part a, calculate how long it would take a molecule of C4H7S to reach your nose if you were 150 m from the skunk. c Does the calculation that you performed in part b provide an accurate estimate for the length of time it would take for the molecule to travel 150 m, or is there something that was overlooked in performing the calculation?arrow_forwardA sample of natural gas is 85.2% methane, CH4, and 14.8% ethane, C2H6, by mass. What is the density of this mixture at 18C and 771 mmHg?arrow_forward
- A chemist weighed out 5.14 g of a mixture containing unknown amounts of BaO(s) and CaO(s) and placed the sample in a 1.50-L flask containing CO2(g) at 30.0C and 750. torr. After the reaction to form BaCO3(s) and CaCO3(s) was completed, the pressure of CO2(g) remaining was 230. torr. Calculate the mass percentages of CaO(s) and BaO(s) in the mixture.arrow_forwardSulfur trioxide, SO3, is produced in enormous quantities each year for use in the synthesis of sulfuric acid. S(s)+O2(g)SO2(g)2SO2(g)+O2(g)2SO3(g) What volume of O2(g) at 350.C and a pressure of 5.25 atm is needed to completely convert 5.00 g sulfur to sulfur trioxide?arrow_forwardUranium hexafluoride, UF6, is a white solid that sublimes (vaporizes without melting) at 57C under normal atmospheric pressure. The compound is used to separate uranium isotopes by effusion. What is the rms speed (in m/s) of a uranium hexafluoride molecule at 57C?arrow_forward
- A 1.0-L flask contains 10.0 g each of O2 and CO2 at 25 C. (a) Which gas has the greater partial pressure, O2 or CO2, or are they the same? (b) Which molecules have the greater rms speed, or are they the same? (c) Which molecules have the greater average kinetic energy, or are they the same?arrow_forwardThe graph here represents the distribution of molecular speeds of hydrogen and neon at 200 K. a Match each curve to the appropriate gas. b Calculate the rms speed (in m/s) for each of the gases at 200 K. c Which of the gases would you expect to have the greater effusion rate at 200 K? Justify your answer. d Calculate the temperature at which the rms speed of the hydrogen gas would equal the rms speed of the neon at 200 K.arrow_forwardA mixture contained calcium carbonate, CaCO3, and magnesium carbonate, MgCO3. A sample of this mixture weighing 7.85 g was reacted with excess hydrochloric acid. The reactions are CaCO3(g)+2HCL(aq)CaCl2(aq)+H2O(I)+CO2(g)MgCO3(s)+2HCL(aq)MgCl2(aq)+H2O(I)+CO2(g) If the sample reacted completely and produced 1.94 L of carbon dioxide, CO2, at 25C and 785 mmHg, what were the percentages of CaCO3 and MgCO3 in the mixture?arrow_forward
