There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below
There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.

What are the ending materials in a chemical reaction called?
The ending materials in a chemical reaction are called products. These are the substances that are formed as a result of the chemical reaction taking place.
What is the products of a chemical reaction?
The products of a chemical reaction are the substances that are formed as a result of the reaction taking place. These products can be different compounds or elements from the reactants that were present before the reaction occurred.
What does the word product mean in a chemical reation?
It means "make." For instance, if hydrogen and oxygen react together, they produce, or make, water.When talking about a chemical reaction, there are reactants, which are the things that go INTO the reaction, and there are products, which are the things that COME OUT. The products are produced in the reaction from the reactant.See the Related Questions links to the left of this answer for more about chemical reactions.

List three signs that could make you think a chemical reaction might be taking place?
Formation of bubbles or gas: Gas evolution can indicate a chemical reaction is occurring. Change in color: A sudden change in color could be a sign of a reaction, such as a shift from clear to cloudy. Temperature change: If the reaction generates heat (exothermic) or absorbs heat (endothermic), it can be an indication that a chemical reaction is taking place.
