How would you capture gas formed in a reaction using the glassware given in the laboratory manual?

To capture gas formed in a reaction, you can use a gas collection apparatus such as a gas syringe or a gas collection tube.

1. Gas syringe: Attach a gas syringe to the reaction vessel using a rubber stopper with a hole in it. As the gas is produced in the reaction, it will be collected in the syringe. Make sure to keep the plunger of the syringe closed to prevent the gas from escaping.

2. Gas collection tube: Place a gas collection tube filled with water upside down in a beaker of water. As the gas is produced in the reaction, it will displace the water in the tube and collect at the top. Make sure to keep the open end of the tube submerged in the water to prevent the gas from escaping.

Both of these methods will allow you to capture the gas formed in the reaction and measure its volume. Remember to handle the gas collection apparatus carefully to avoid any leaks or spills.
