Question 1
Different substances have different properties that can be used to identify them. There are three test tubes X, Y, and Z filled with gas.
Can the properties of the gas in each test tube be used to tell whether the gases are the same or different?
What do you think might happen when a gas is exposed to a small flame? List as many possible results as you can think of

The properties of the gas in each test tube can be used to tell whether the gases are the same or different, because depending on the substance, chemical reactions will occur.

What do you think might happen when a gas is exposed to a small flame?

This happens in the flame test, which is based on the fact that when a certain amount of energy is supplied to a certain chemical element (in the case of a flame, energy in the form of heat), some electrons in the last valence shell absorb this energy.

Moving to a higher energy level, producing what we call an excited state. When one of these excited electrons returns to the ground state, it releases the energy previously received in the form of radiation.

With this information, we can conclude that the properties of the gas in each test tube can be used to know if the gases are the same or different, because depending on the substance, chemical reactions will occur.
