Answer to Problem 14TE
The chemical reaction in a disposable battery is an exothermic reaction and the chemical reaction in the recharging process of the rechargeable battery is an endothermic reaction.
Explanation of Solution
The process of the conversion of reactant species into the product species is called a chemical reaction.
There are two main types of chemical reactions based on the exchange of energy.
The chemical reaction where the energy is absorbed in the system from the external area or the surrounding is the endothermic type of reaction.
The chemical reaction where the energy is released to the surrounding from the area of interest or the system is the exothermic type of reaction.
The disposable battery is a type of battery that releases energy. Hence, the disposable battery has an exothermic type of reaction.
The disposable battery is of no use after once it is used but the rechargeable battery can be used again and again.
The rechargeable battery has two processes involved in it, discharging and recharging reactions. The exothermic reaction occurs during the discharging process and an endothermic reaction occurs in the recharging process because it requires a high input of energy.
Conclusion:
Therefore, the chemical reaction in a disposable battery is an exothermic reaction and the chemical reaction in the recharging process of the rechargeable battery is an endothermic reaction.

- In a scene from The Avengers (the first one) Black Widow is boosted directly upwards by Captain America, where she then grabs on to a Chitauri speeder that is 15.0 feet above her and hangs on. She is in the air for 1.04 s. A) With what initial velocity was Black Widow launched? 1 m = 3.28 ft B) What was Black Widow’s velocity just before she grabbed the speeder? Assume upwards is the positive direction.arrow_forwardIn Dark Souls 3 you can kill the Ancient Wyvern by dropping on its head from above it. Let’s say you jump off the ledge with an initial velocity of 3.86 mph and spend 1.72 s in the air before hitting the wyvern’s head. Assume the gravity is the same as that of Earth and upwards is the positive direction. Also, 1 mile = 1609 m. A) How high up is the the ledge you jumped from as measured from the wyvern’s head? B) What is your velocity when you hit the wyvern?arrow_forwardA) If Yoshi flings himself downwards at 9.76 miles per hour to hit an enemy 10.5 m below him, how fast is Yoshi traveling when he hits the enemy? 1 mile = 1609 marrow_forward
