Yes.
yes
The usual reaction is with acid which would produce carbon dioxide gas
Heat would speed up the reaction, while cold would slow the reaction.
Baking is a chemical reaction for a few reasons. First off, heat is being applied to change a substance (cake mix / batter) into another substance (baked cake). Reactions occur such as water and moisture turning to steam as a result of the heat, and ingredients like water and baking soda / powder react to create a fluffy cake.
A good example would be a reaction between vinegar and Baking soda. The 2 react to form a gas.
"New substances" is a vague description of what happens in a chemical reaction. Simply put though, yes. An example of this would be if you took baking powder and vinegar and mixed them together, the resulting chemical reaction would create Carbon Dioxide. That is a new substance, it wasn't there until the reaction took place.
Bleaching is a chemical reaction.
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
That would be the product of the chemical reaction.
A chemical reaction can be represented by a chemical equation.
Yes, baking a potato would be considered a chemical change. Typically, anything that involves heat, such as in cooking, is a chemical change due to molecules being chemically altered.
