3) The figure below represents the moving particles of a gas within a rigid container. Each circle represents a single submicroscopic gas particle. Of course, real particles DO NOT have tails behind them. The tails are an attempt to indicate the relative motion of the particles. In the space to the right of the figure, redraw the diagram as it would appear after the container was heated. Briefly justify/explain your drawing. Redrawn After Heating: Original Temperature: O 110 O'll 111-O

A weather balloon is inflated to a volume of 29.8 L at a pressure of 753 mmHg and a temperature of 25.3 ∘C. The balloon rises in the atmosphere to an altitude where the pressure is 390. mmHg and the temperature is -16.7 ∘C. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

A helium-filled weather balloon has a volume of 709 L at 22.9°C and 757 mmHg. It is released and rises to an altitude of 7.43 km, where the pressure is 351 mmHg and the temperature is -26.1°C. The volume of the balloon at this altitude is L.

Sometimes in Io we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. collected gas Suppose the O, gas evolved by a certain chemical reaction taking place at 30.0 °C is collected over water, using chemical reaction water an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 44.8 mL. Sketch of a gas-collection apparatus ab Calculate the mass of O, that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases. Explanation Check O 2022 McGraw Hill LLC. All Rights Reserved.

The compound Mg(ClO3)2 decomposes when heated according to the equation below. Mg(ClO3)2 (s) ➝ MgCl2 (s) + 3 O2 (g) An impure sample of material contains a small amount of Mg(ClO3)2 . The sample is heated and the gas produced collected by downward displacement of water. A total of 377.1 ml of gas is collected at a temperature of 20.0ºC when the atmospheric pressure is 740.0 torr. [The vapor pressure of water at 20.0ºC is 17.54 torr.]Calculate the number of grams of Mg(ClO3)2 present in the impure sample. Grams of Mg(ClO3)2 : Answer in grams

Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.) The pressure of a gas in a fixed volume increases when its temperature increases. Select one or more: The average kinetic energies of gas particles increase with an increase in temperature. Gas particles are widely spaced. A gas consists of many small particles in rapid, random motion. The total volume of the molecules themselves is very small compared to the volume of the container. There are virtually no attractive forces between gas particles.

A helium-filled weather balloon has a volume of 731 L at 23.9°C and 754 mmHg. It is released and rises to an altitude of 2.07 km, where the pressure is 641 mmHg and the temperature is 9.9°C. a. The volume of the balloon at this altitude is  L.       2.  A sample of helium gas at a pressure of 761 mmhg and a temperature of 32ºc, occupies a volume of 8.71 L. If the gas is cooled at constant pressure to a temperature of 11ºc, the volume of the gas sample will be   L.

A piece of dry ice (solid carbon dioxide) with a mass of 25.5 g sublimes (converts from solid to gas) into a large balloon. Assuming that all of the carbon dioxide ends up in the balloon, what is the volume of the balloon at 27 ∘C and a pressure of 735 mmHg ? Express your answer to three significant figures.
