Based on relative bond strengths, classify these reactions as endothermic (energy absorbed) or exothermic (energy released)

1 answer:

5 0

<span>Exothermic reaction is a chemical reaction that releases energy. This reaction releases heat energy or light . In an endotermic reaction energy is used. Enthaply is the heat energy change , delta H. If the sum of the enthalpies of the reactans is greater than the products the reaction is exothermic. If the products side has a larger enthaply than the process is endothermic. So, if delta H is negative then the process is exothermic. If delta H is positive, than the process is endothermic. Exothermic are: A+BC -> AB+C A2+B2 -> 2AB Endothermic are:AB+C -> AC+B A2 + C2 -> 2AC B2+C2 -> 2BC</span>

Why is a pond appears shallower than it actually is?

larisa86 [58]

Answer:

Below:

Explanation:

Consider two rays originating from the bottom of the pond. As these rays get refracted into the air, they bend away from the normal. ... This point gives the apparent position of the bottom of the pond, therefore, the pond appears to be shallower.

Hope it helps....
