Question

Classify the following statements/ pictures as either an endothermic or exothermic reaction. (3 points)

Chemical reactions where heat is absorbed from the surroundings … Indicated by a FALL in temperature (feels cold)



The stored energy of the products is greater than the stored energy of the reactants.






Chemical reactions where heat is released to the surroundings… Indicated by a RISE in temperature ( feels hot)






a. Endothermic
b. Exothermic

Answer 1

1.endothermic

2.exothermic

3.exothermic

Step-by-step explanation:

In endothermic reactions the energy is absorbed that means energy in products is greater than the energy in products.But in exothermic reactions the energy is released therefore energy in reactants is greater than products

Answer 2

1. The graph like-looking picture that has an arrow pointing up towards (energy absorbed), has the answer of Endothermic

2. The equation that shows O2(g) --->CO2(g) + H2O(I) + Energy has the answer of Exothermic

3. The picture that has the arrow pointing downwards towards (energy released) has the answer of Exothermic

4. The equation that shows 6CO2 + 6H2O + Energy ---> C6 H12 6O2 has the answer of Endothermic

5. The picture that has a beaker with the word heat pointing towards it and has the word entropy pointing downward, has the answer Endothermic

6. The picture that has the beaker with the word heat pointing away from it and the word entropy pointing upwards, has the answer Exothermic

I hope this helps you! Good luck on that test ya'll
