The question is not clear but the reaction is called a chemical reaction. It may be burning wood or paper and it turns to ash or mixing vinegar with baking soda and getting a new type of gas.
A phase change.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
A chemical change occurs when this happens.
A homogenous mixture
physical=A physical change does not produce a new substance. chemical= A chemical change produces a new substance. u now have the answer........
The "blank form" could be "state".
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.

water!
chemical .
Heat is transferred.

This is a gas, due to it not actually having a definite volume.

This is a typical chemical reaction.
