Chemistry In Context
- A flask equipped with a valve contains 3.0 mol of H2 gas. You introduce 3.0 mol of Ar gas into the flask via the valve and then seal the flask. a What happens to the pressure of just the H2 gas in the flask after the introduction of the Ar? If it changes, by what factor does it do so? b How do the pressures of the Ar and the H2 in the flask compare? c How does the total pressure in the flask relate to the pressures of the two gases?arrow_forwardCalculations ( Lab Data is Linked) 1. Determine the number of moles of hydrogen gas that was produced with the complete reaction of the magnesium metal with excess hydrochloric acid. 2. Using Dalton's Law of Partial Pressure and the vapor pressure of water, determine the partial pressure of dry hydrogen gas. 3. Using the ideal gas law based on the collection of dry hydrogen gas, calculate the value of ideal gas law constant, R.arrow_forwardGas exercise: What volume does a gas occupy at 980 mmHg, if the container finally has a pressure of 1.8 atm and the gas is compressed to 860 cc?arrow_forward
- Trial #1: A piece of magnesium with a mass of 0.330 grams was placed into a solution of hydrochloric acid. 335 mL of hydrogen gas were produce when this reaction occurred at 22.0 °C and a pressure of 747.0 mmHg. Mg(s) + 2HCl(aq) ⟶⟶ H2(g) + MgCl2(aq) What is the pressure in trial reported in atmospheres?arrow_forwardA sample of a gaseous substance at 25C and 0.862 atm has a density of 2.26 g/L. What is the molecular weight of the substance?arrow_forwardResearch the most recent measures taken by countries around the world to reduce CFCs in the atmosphere since the Montreal Protocol. Writea short report describing the Montreal Protocol and more recent environmental measures to reduce CFCs.arrow_forward
- A volume of carbon dioxide gas, CO2, equal to 20.0 L was collected at 23C and 1.00 atm pressure. What would be the volume of carbon dioxide collected at 23C and 0.830 atm?arrow_forwardtrong>Exercise 13.3 A child blows a bubble that contains air at 28Cand has a volume of 23cm3at I atm. As the bubble rises, it encounters a pocket of cold air (temperature 18C). If there is: no change in pressure, will the bubble get larger or smaller as the air inside cools to 18C? Calculate the new volume of the bubble.arrow_forwardTrial #1: A piece of magnesium with a mass of 0.330 grams was placed into a solution of hydrochloric acid. 335 mL of hydrogen gas were produce when this reaction occurred at 22.0 °C and a pressure of 747.0 mmHg. Mg(s) + 2HCl(aq) ⟶⟶ H2(g) + MgCl2(aq) What is the temperature of this trail reported in Kelvin? What is the pressure in this trial reported in atmospheres?arrow_forward
- Calculate the density of helium, He, in grams per liter at 21C and 752 mmHg. The density of air under these conditions is 1.188 g/L. What is the difference in mass between l liter of air and 1 liter of helium? (This mass difference is equivalent to the buoyant, or lifting, force of helium per liter.)arrow_forwardPractice Exercise 1If you fill your car tire to a pressure of 32 psi (pounds persquare inch) on a hot summer day when the temperature is35 °C 195 °F2, what is the pressure (in psi) on a cold winterday when the temperature is -15 °C 15 °F2? Assume no gasleaks out between measurements and the volume of thetire does not change.(a) 38 psi (b) 27 psi (c) -13.7 psi (d) 1.8 psi(e) 13.7 psiarrow_forward
