Termochemical reactions include the enthalpy of reactants and products.
To show it is a solid or a liquid or a gas
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
An equation showing only what is involved in the reaction (apex)
In a chemical reaction, various substances can be made or produced. These can include new compounds, such as when two or more elements react to form a compound, or changes in the physical state of a substance, such as when a liquid evaporates to form a gas. Additionally, energy can also be released or absorbed during a chemical reaction.
Three signs of a chemical reaction include the release or absorption of heat, a change in color, and the creation of a gas or a precipitate.
change in enthalpy.
Yes, it is true. But in my opinion these equations have no sense manner.

A net ionic equation.

No. They include their energy source, to glow for a while (thanks to a chemical reaction).
Chemical reactions can be recognized by many things, but mainly include a change in color, a variation in temperature, change in shape, or the creation of bubbles.
Evidence that a chemical reaction has taken place usually include appearance of a precipitate, change in color, or production of a gas.
The signs of a chemical reaction include change in temperature, change in color, formation of gas, formation of a precipitate, disappearance of a solid, formation of a new odor.
