During a chemical reaction, what happens to the atoms of the reactants?
AThey are rearranged into new compounds
BThey are destroyed inside the flask
CThey are created out of the liquid
DThey are changed into new elements
Answer & Solution
Correct answer: A. They are rearranged into new compounds
1. Old bonds between atoms break and new bonds form during a reaction.
2. The same atoms end up joined in different combinations.
3. So a chemical reaction is a rearrangement of atoms into new compounds.
4. Atoms are neither created nor destroyed in a chemical reaction, which rules out two options.
