If you would be melting ice, and you collected all the water dripping off the melting icecube and put it into an icecube maker, and stuck it in the freezer, you would be reversing the chemical change. I think?
The water formed in the space shuttle's rockets could be split into hydrogen and oxygen by using an electric current.
Hope this helps! (:
An example of a chemical change reserved is the water formed in the space shuttle's rockets could be split into hydrogen and oxygen by using an electric current.
It Looks like your tryhing to cheat on Science TeeHee Chemical changes cannot be reversed but phyical changes can ! I disagree. Some chemical changes can be reversed. If you boil off the water and catch it in a container when it evaporates, the water will be back. If you then look at the bottom and possibly sides of your beaker there will be only salt left behind.
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Change of state from a liquid to a solid and back again.
A reversible change is when something can turn back into its original shape for example when ice is melted it turns into a liquid but then you can freeze it into a solid again do the change is reversible because it can change back into its original starter which is the ice in this case. But if you make a cake it is not reversible because all of the mixture has mixed together and it turns into one object this is called a chemical change. Also a reversible change is a physical change! Hope this helped ;)
because they may be hazardous to your health, for example you could inhale a chemical and it will start to eat away at your insides

it can not be reserved if you triedsorry that answer is wrongI dont know the real answer
yes
No. When there is a chemical change, the effects cannot be reversed.

There are many different chemical changes that could happen in a car. The conversion of fuel for example is a chemical change.
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account. When water evaporates, it can condense back into liquid water. It can be reversed because it is a physical change. Chemical changes are often permanent. Take the burning of wood, for example. This is a chemical change. Once you light wood on fire, it turns into gas. Only the trees and plants around you can take this gas and through photosynthesis, turn it back into wood. So it is a non-reversible process, and is a chemical process.
Some chemical changes are baking a cake and a rusting bicycle.Another chemical changes could be:Nail rustingWood burningSouring of milkDigestingColoring hairSome chemical changes are rusting of iron, food metabolizing in the body, milk going sour, grilling a hamburger, and electroplating a metal.

wind and water
There are a number of changes that you could make at your college. You could start programs for charities or school activities for example.
