One significant reason for social change in the past 100 years is the rise of technology and communication, which has facilitated the rapid spread of information and ideas.

Additionally, global events, such as wars and economic shifts, have prompted reevaluations of societal norms and values, leading to reforms in areas like civil rights, gender equality, and environmental awareness.
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.

The change in color indicates that a chemical reaction has taken place.
The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place.
You might observe a change in color, gas bubbles being formed, a change in temperature (this might require the use of a thermometer, unless the solution actually boils), or you can test for a specific chemical by using an indicator, or analyse the solution by means of a mass spectrometer. Explosions are also a very convincing form of evidence that a chemical change has taken place.
