Is curdling of milk physical or chemical?
The curdling of milk is a chemical process. It occurs when proteins in the milk, such as casein, interact with an acid (like lemon juice or vinegar), causing the proteins to denature and clump together, forming curds. This process is irreversible and results in a change in the composition of the milk.
What are the five ways to know that chemical reaction happened?
don't know
How we know a chemical change has occurred when burning a candle?

What is the correct balanced chemical equation for this reaction?
To provide the balanced chemical equation, I would need to know the specific reaction you are referring to. Can you please provide the reactants and products involved in the reaction?
Does energy change in a chemical reaction?
yes it does i didnt know that at first but it does
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
How do bears know when to hibernate?
Usually when the weather gets cold, they are triggered to hibernate. That's the most logical reason anyway. It may have to do with a some sort of chemical reaction the cold weather does, but most likely it's just an instinct. :) Hope this helps! :) Isabella246 :D

Why do you have to balance chemical equations?
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).
