Why does a change in teperature indicate that a change reaction may have occured?
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
Why is churning a chemical change?
Churning is not a chemical change, but a physical change. It involves breaking up larger molecules, like fat globules in milk, into smaller ones through mechanical action, without altering their chemical composition. Chemical changes involve the formation of new substances with different chemical properties.
Is enzyme in saliva a physical or chemical change?
i know that its physical change because all you saliva is doing is making the food wet
Is making Rice A Roni a chemical change?
Yes, because the preparation involve chemical processes.
Is the process of making sugar a chemical change?
Yes, it is true; this technology involve chemical processes.
Chemical reactions involve the making and breaking?
chemical bonds
Is making iron from iron ore a chemical or physical change?
Preparation of pure iron from iron ores involve physical changes but also chemical changes.
What are three Chemical Reactions or Physical changes that happen in the process of making S'mores?
three physical changes of making a s'more would be breaking the chocolate, breaking the crackers, and chewing the s'more when it's in your mouth.
Every Chemical Reaction Involves A?
Every chemical reaction involves a rearrangement of atoms and bonds between reactant molecules to form new product molecules. This process can result in the breaking of existing bonds and the formation of new bonds, leading to the transformation of substances from one form to another.
Is a chemical change easier to reverse then a physical change?
No, chemical changes are typically more difficult to reverse than physical changes. Chemical reactions involve the creation of new substances with different chemical properties, making it challenging to reverse the reaction and return to the original substances. Physical changes, such as changes in state or shape, usually involve rearranging the same particles and are more easily reversible.

Which is easier to reverse chemical or a physical change?
Physical changes are generally easier to reverse than chemical changes. Physical changes involve a change in state or appearance without altering the chemical composition of a substance, so reversing the change often involves a simple process like melting, freezing, or evaporating. In contrast, chemical changes involve the formation of entirely new substances with different chemical properties, making them more challenging to reverse.
What does chemical reaction have to do with making and breaking bonds?
Chemical reactions involve the breaking of bonds in reactant molecules and the formation of new bonds in product molecules. During a reaction, old bonds are broken as energy is absorbed, and new bonds are formed as energy is released. The breaking and forming of chemical bonds are essential for rearranging atoms and creating new substances during a reaction.
