which statement correctly describes a chemical reaction? energy is always released. products go into a reaction. reactants come out of a reaction. bonds between atoms break and reform.

Explanation:

• Analyze each option:
• "Energy is always released": Chemical reactions can be endothermic (absorb energy) or exothermic (release energy), so this is incorrect.
• "Reactants come out of a reaction": Reactants are the substances that go into a reaction, products come out, so this is incorrect.
• "Products go into a reaction": Products are the result of a reaction, reactants go in, so this is incorrect.
• "Bonds between atoms break and reform": In a chemical reaction, reactant bonds break, and new bonds form to make products, which is a fundamental aspect of chemical reactions.

Answer:

Bonds between atoms break and reform.
