When baking soda and vinegar are mixed together bubbles form and the vinegar and baking soda are changed into new chemicals. is this an example of physical or chemical or both physical and chemical or neither physical nor chemical?

Its a chemical change.

Explanation:

When baking soda and vinegar are mixed bubbles formed and new product is formed by both reactant. So its a chemical change because in a chemical change new substances are formed.

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:

H 2 (g)  + O 2  (g) > 2H 2O  (l)

*tilts head* sounds more like a statement

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
