Yes, baking a pretzel involves a chemical reaction, primarily through the process of Maillard reaction and caramelization. As the dough heats, proteins and sugars react to create complex flavors and the characteristic brown color of the crust. Additionally, the baking process causes the dough to rise due to the release of gases, further transforming its texture and structure. These changes are irreversible, signifying a chemical transformation.
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.
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.
When orange juice and baking soda are mixed, a chemical reaction occurs between the citric acid in the juice and the sodium bicarbonate in the baking soda. This reaction produces carbon dioxide gas, which creates bubbles and fizzing. The mixture may also create some foam due to the release of carbon dioxide.
When baking soda is added to yogurt, a chemical reaction occurs due to the acidity of the yogurt. The baking soda will react with the acid in the yogurt, producing carbon dioxide gas, which causes the mixture to rise and become bubbly. This reaction can be used in recipes to create a light and fluffy texture in baked goods.
That would be the product of the chemical 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.
