What type of change that produces a new substance?

Answer 1

If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.

Answer 2

A Chemical reaction produces a new chemical. there are many types of chemical reactions. when you burn something, it is changed into a new compound. When heat or light is given off by the reaction, it is a good indicator a chemical reaction has taken place. Simple phase shift such as water evaporating is not a chemical reaction.

Answer 3

Transmutation is the forming of a different element by radioactive decay or by neutron absorption. In chemical reactions elements always stay the same, but get rearranged into different combinations of molecules.

Answer 4

Such a change in which a new substance is formed is a chemical change .

In a chemical change, the chemical composition of the substance undergoing change changes. It involves breaking of the chemical bonds in the reactant and formation of new bonds in the products with the evolution or absorption of energy.

Answer 5

A change that produces a new substance would be a chemical change.

Answer 6

Chemical
