match these with this
a. exothermic
b.endothermic
energy is a reactant - b. endothermic
energy is a product - a. exothermic
the products have higher energy than the reactants - a. exothermic
the reactants have higher energy than the products - b. endothermic
energy is absorbed - b. endothermic
energy is released - a. exothermic
To match the statements with the corresponding terms "exothermic" and "endothermic," we need to understand the definitions of these terms.
Exothermic reactions release energy into the surroundings. They occur when the products have lower energy than the reactants. In exothermic reactions, energy is usually released in the form of heat, light, or sound.
Endothermic reactions absorb energy from the surroundings. They occur when the products have higher energy than the reactants. In endothermic reactions, energy is usually absorbed in the form of heat.
Now let's match the statements:
1. Energy is a reactant: This statement suggests that energy is involved in the reactions before the reaction occurs. In this case, energy is required as a reactant, indicating an endothermic reaction. Therefore, we can match it with (b) endothermic.
2. Energy is a product: This statement suggests that energy is generated and appears as one of the products of the reaction. This indicates an exothermic reaction, where energy is released. Therefore, we can match it with (a) exothermic.
3. The products have higher energy than the reactants: This statement suggests that the chemical reaction has resulted in an increase in energy. Therefore, it indicates an endothermic reaction. We can match it with (b) endothermic.
4. The reactants have higher energy than the products: This statement suggests that the chemical reaction has resulted in a decrease in energy. Therefore, it indicates an exothermic reaction. We can match it with (a) exothermic.
5. Energy is absorbed: This statement indicates that energy is taken in from the surroundings during the reaction. This aligns with an endothermic reaction. Therefore, we can match it with (b) endothermic.
6. Energy is released: This statement indicates that energy is given off to the surroundings during the reaction. This aligns with an exothermic reaction. Therefore, we can match it with (a) exothermic.
Matching the statements with the terms:
a. Exothermic:
- Energy is a product
- The reactants have higher energy than the products
- Energy is released
b. Endothermic:
- Energy is a reactant
- The products have higher energy than the reactants
- Energy is absorbed
a. exothermic: energy is released, the products have higher energy than the reactants
b. endothermic: energy is absorbed, the reactants have higher energy than the products
