Not unless it is a reversible reaction (Such as the Haber Process). If it is not reversible, you cannot get the same substances back.

If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
Why is sugar dissolving in tea a chemical reaction?
It isn't. When sugar dissolves it is still the same substance, it's just mixed with the tea. Chemical changes involve the formation of a new substance.
When a chemical reaction occurs the compounds remain the same as before the reaction?
After a chemical reaction the reactants are transformed in products.
What is the word for a chemical change in a substance?
A chemical change is the same as a chemical reaction.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
How are reactants and products treated the same and a chemical reaction?
use formulas to represent the substance involved in a reaction.
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Why cant a chemical reaction be put back the same?
cause chemical reactions cant be reversed
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
Why is sugar dissolving in tea a chemical reaction?
It isn't. When sugar dissolves it is still the same substance, it's just mixed with the tea. Chemical changes involve the formation of a new substance.
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
Chemical change same as chemical reaction?
no because a chemical change is any process in which 1 or more substance is changed into 1 or more substances whereas a chemical reaction is a process that leads to a transformation of one set of chemical substances to another
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
Is a compound an example of a chemical change?
All samples of a compound have the same composition; that is a chemical reaction that takes place and a new substance is formed. So yes.
