Concept explainers

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

Textbook Question

Chapter 8, Problem 8.3E

Two small metallic bodies are given opposite charges, with the negatively charged body having twice the charge of the positively charged body. They are immersed in water (dielectric constant = 78 ) at a distance of 6.075 cm , and it is found that the force of attraction between the two metal pieces is 1.55 × 10 − 6 N . (a) What are the charges on the pieces of metal? (b) What are the electric fields of the two bodies?

I need help with the following two problems, understanding them in a simple manner. Can you please draw them out for me with a detailed explanation so that I can better comprehend? I'm a visual person, so I definitely need that. Thank you very much!

Problem 54, could you please explain it in detail? Thank you! Step by step, I'm really confused, so please don't make it overly complex. My question is to visually draw it out and demonstrate it to me; I'm confused about that problem, please (not just in words) but demonstrate it to me in all due essence (visually) with descriptions.
