Step 1
B. In the beaker, chemical energy stored in the reactants is converted to heat energy.
Answer
This statement is correct because during chemical reactions, especially in redox reactions, some of the energy stored in the chemical bonds is indeed converted into thermal energy (heat). This is a fundamental aspect of exothermic and endothermic reactions.
