What chemical reaction takes place when baking brownies?
when its baking in the oven.
"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.
It is a chemical reaction. The formation of a gas is evidence that a chemical reaction has taken place. Baking soda (sodium bicarbonate, NaHCO3) reacts with vinegar (dilute acetic acid, CH3COOH) to form carbon dioxide gas plus water plus sodium ions and acetate ions (the ions are dissolved in water). NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq) https://www.thoughtco.com/equation-for-the-reaction-of-baking-soda-and-vinegar-604043
I am guessing that you are studying the 360 Edexcell science GCSE course but even if you not this is still relevant. Baking a cake is a chemical reaction. A chemical reaction is a reaction that takes place and you can't separate the product into the reactants again. It is usually studied to show how the carbon dioxide is formed by the reaction of Sodium hydrogen carbonate with Tartaric acid to eventually form the bubbles…
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
Many chemical reactions take place but the most noticeable one is the maillard browning reaction. The amino acids from the eggs combine with the reducing sugars when baked in the oven to produce melanoidins which are a brown pigment. Another important reaction occurs due to the baking soda (sodium bicarbonate). When the cookies are baked the baking soda reacts with an acid ingredient to produce carbon dioxide, water and a sodium salt. The carbon dioxide…
