Sometimes in lab 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. Suppose the CO₂ gas evolved by a certain chemical reaction taking place at 40.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 87.0 mL. collected gas X water chemical reaction Sketch of a gas-collection apparatus Calculate the mass of CO₂ 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. BEET Ar B
An old gas cylinder you found lost its label. Lab supervisor is pretty sure that it is either He, Ne, Ar or Kr and you were tasked to figure out which one. What you did was that you transferred some of the gas from the old cylinder into an evacuated 10-L flask until the gauge pressure inside reached 1.00 atm. After sealing it, you carefully weighed the gas-filled flask and figured out that the mass of the gas (excluding that of the flask) was 15 g. If the temperature and barometric pressure in the lab was 27°C and 1 atm, what was the gas?
A gas storage cylinder in an ordinary chemical laboratory measures 7.1 cm wide and 28. cm high. This is the label on it.

2. Sodium sulfide (0,1159 g) and excess hydrochloric acid were reacted together to form 35.75 mL of an unknown gas. The gas was collected over water when the atmospheric pressure was measured to be 767 mmHg. The temperature of the water was 23.0°C. Determine the molar mass, as well as identity, of the gas. Hint: You will need to reference your textbook for the vapor pressure of water.
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.
