Bread going moldy is considered a chemical change because it involves the transformation of the bread's composition through microbial activity. Mold, a type of fungus, breaks down the carbohydrates and proteins in the bread, leading to the formation of new substances and changes in texture, flavor, and appearance. This process is irreversible; once the bread has molded, it cannot return to its original state. Therefore, the mold growth signifies a fundamental chemical alteration in the bread.
Yes, it is a chemical reaction.
both. the clothes becomes wet which is a physical change and the chemicals in the soda going through the fabric of your clothes is a chemical change.
Melting steel is a physical change because only its physical state is altered, going from a solid to a liquid, without changing its chemical composition.
C6H12O6(s) ===> C6H12O6 (g)Sublimation is going from a solid (s) to a gas (g) without going through the liquid phase. The chemical composition of the compound does not change.
When something is alive, there are chemical reactions going on constantly within it. The technical definition of being deadis that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead.So, in short, dying (that is, ceasing to be alive) is nota chemical change. Instead, dying is a lack of chemical change.
Bread going moldy is a chemical change
how do you stop food going moudly
Yes, it is a chemical reaction.
Bread has the right environment for mould spores to grow. It is warm (if kept out of the fridge), has a moisture content & the surface is textured perfectly for mould spores to take. Therefore it is a perfect host for their growth. As the mould spores grow, they consume the moisture in the bread and they spread into larger moulds as they consume more water. So in response to it being a chemical or physical change, there is something of both processes occurring. As the mould grows there are enzymes being produced by the mould which affect the bread and change its chemical nature, also the physical change is obvious as the bread shrivels due to dehydration. Also the colour and texture constitute a physical change. Hope this helps
These marshmallows are going through a chemical change. How is this different from a physical change?
Chemical. If anyone wants to put more detail, please do.
Mold on bread is a chemical change. There are actually two chemical changes going on here. Mold, a living organism, is consuming the sugar, water and minerals in the bread. Also, the bread is decomposing. These changes are irreversible, they release smelly gases, and they produce a small amount of heat. So yes, mold on bread IS a chemical change. (:
Because a chemical reaction has different sign's. And heat is one. But if the temperature is dropping then it is not going through a chemical change.
Yes, beer going flat is a physical change rather than a chemical change. When beer loses its carbonation, the molecules within the beer are simply rearranging themselves, rather than undergoing a chemical reaction that changes their composition.
A change of temperature implies that some energy has been transfered or used. Since chemical reactions either require or release energy to occur, the environment may change temperature as the substances react.
The future tense is: will get -- We will get some bread. am/is/are going to get -- We are going to get some bread. am/is/are getting -- I am getting some bread.
You think probable to catalysts.
