Is making an orange juice an irreversible change?
In a way yes and in a way no. For the individual orange, squishing it to juice is irreversible. However oranges are the result of biological processes and the biological cycles will reproduce a new orange.
Whether the change caused in tar by heating is reversible?
it can't be changed,i.e.,irreversible change...
What are the three product that result when flavoproteins reduce oxygen?
The flavoprotein amino acid oxidases (AAOs) catalyze an essentially irreversible oxidative deamination of an amino acid. Molecular oxygen is the oxidant and the products are ammonia, the oxoacid, and H2O2
When a substance dissolves it undergoes a chemical change physical change molecular change?
When a substance dissolves, it undergoes a physical change, not a chemical change. This is because the molecules of the solute are dispersed in the solvent but do not undergo any chemical reactions. The process of dissolving is a result of the attraction between the solute and solvent molecules.
What are chemical reactions a result of?
They are the result of two or more reactants usually combining. You can identify when a chemical reaction has occured by a change of state being physical e.g. liquid to gas. The product may change in colour, taste, smell, temperature, size etc. You can also tell if it starts to effervest - bubble. There are reversible and irreversible chemical reactions. Reversible is obviously when you can change the effects e.g. you can melt and re-solidify water whereas irreversible you can't e.g. can't turn ash back into wood when burnt. Hope that helps (;
Why is a chemical change normally permanent in nature?
A chemical change is typically permanent because it involves the breaking and forming of chemical bonds, resulting in the creation of new substances with different properties. Unlike physical changes, where the original substances can often be recovered, chemical changes rearrange atoms at a molecular level, making it impossible to revert to the original materials without undergoing another chemical reaction. As a result, the changes are often irreversible under normal conditions.
What does runaway climate meas?
Runaway climate change refers to a scenario where positive feedback loops in the Earth's climate system lead to an uncontrollable increase in global temperatures, causing widespread and severe impacts such as melting ice caps, rising sea levels, and extreme weather events. This could result in irreversible damage to ecosystems and human societies.
What type of radiation causes delayed irreversible changes of the skin cause radiation burns?
Beta radiation is known to cause delayed irreversible changes to the skin, leading to radiation burns. These burns can occur as a result of prolonged exposure to beta radiation sources and can result in long-term damage to the skin.
Why does an energy transfer not always result in a phase change?
An energy transfer does not always result in a phase change because the energy can be used to increase the temperature of a substance without causing it to change from one phase to another. Phase changes occur when a substance reaches a specific temperature and energy level that causes its molecular structure to rearrange, such as melting or boiling.
Is Giving off light a physical change?
Giving off light is considered a chemical change, not a physical change. This is because the emission of light usually involves chemical reactions at the atomic or molecular level that result in the production and release of photons.
What does geographical change mean?
A geographical change means one which occurs to the land and its features. This can be a result of natural events like flood or erosion which slowly eat away at the Earth's surface.
Is an increase in gas pressure a result of an increase in molecular collisions?
