Methods of Collecting Oxygen

A. Oxygen can be collected in a test tube placed upside down.

The statement that oxygen can be collected in a test tube placed upside down is true. This method is commonly used in laboratory settings to collect gases, including oxygen. When a test tube is placed upside down over water, the oxygen produced displaces the water and fills the test tube. This method allows for the collection of gases produced in a reaction.

B. Oxygen cannot be collected by the displacement of water.

The statement that oxygen cannot be collected by the displacement of water is false. In fact, the displacement of water is a common method for collecting gases, including oxygen. When a gas is produced in a reaction, it can displace water in a container, allowing for the collection of the gas.

Therefore, the correct answer is 1. Verne только А (1. True only A).
