Accepted Answer

D. {'text': 'Endothermic'}

1. The arrow indicates that heat is supplied to make the reaction occur.
2. A reaction that **absorbs heat** from its surroundings is called **endothermic**.
3. Example: CaCO₃ + heat → CaO + CO₂.
4. Exothermic reactions release heat; photochemical reactions need light, not heat.
