Is A chemical reaction occurs when a solution is formed true or false?
A substance changing state (i.e. solid to a liquid) is not a chemical change as the composition of the substance has not changed at all. The particles' energy and distance from each other is the only thing that is altered.
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 a process in which a substance or substances is transformed into one or more new substances?
Chemical Change
What happens to a reducing agent as it reduces?
In chemistry, reduction is defined as a phenomenon in which substance gets electron from other species, oxidation is defined as a process in which substance donates electron to other species. When a metal acts as reducing agent, the other substance (for which metal acts as reducing agent) gets electrons (from metal) and by definition goes on reduction, and the metal, in this process, donates electron so, metal itself undergoes to oxidation.
How do you speed up an enzyme reaction?
By adding more substance that the enzyme is acting upon, it forces that enzyme to be faster in order to complete the process.
What is a process in which one or more substance are changed into others?
the process is reaction
Chemical change is what?
A process in which reactants are changed into one or more different products
Is a process in which one or more substances are changed into others?
the process is reaction
Substance that cannot be changed into a simpler substance under normal laboratory conditions?
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
What is the chemical process in which two or more simple substances combine to form a more complex substance?
This chemical process is called synthesis.
A combinatoin of two or more substances in which the basic identity of each substance is not changed?
Mixture
Reaction?
This is the process in which one or more substances are changed into others.

Is it true that a substance produced during a chemical change cannot easily be changed back into the original substance?
generally no, but sometimes yes. if one or more of the products is insoluble or otherwise removes itself from the other products, then the reaction is considered irreversible.
