the synthesis of new chemical chemical by chemists.
After a chemical change new molecules are obtained.
New elements can by obtained only by nuclear reactions.New molecules can be obtained by chemical reactions.
After a chemical change new molecules are obtained.
No
yes
Yes, it is true: all chemical reactions create new molecules of compounds.
Chemical bonds in the starting substances must break. molecules are always moving. if the molecules bump into each other with a enough energy, the chemical bonds in the molecules can break. the atoms then rearrange, and new bonds form to make new substances.
New molecules are formed.
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
You think probable to chemical reactivity.
No, but production of new molecules does happen.
