Usefulness of microscopic, macroscopic and symbolic perspectives in understanding a chemical system should be explained. Concept Introduction The characteristics we can see in a system and reactions happen in the system as a whole are the macroscopic qualities.Therefore, observing characteristics of the whole system refers to the macroscopic perspective. The characteristics of a single atom or a molecule are considered as microscopic properties. Therefore considering those microscopic properties such as speed, size, energy of individual atoms or molecules; is referred to as microscopic perspective. A chemical system consists of atoms. Atom is the smallest unit of a system and it is unimaginably small. Sometimes atoms do not exist alone and form molecules by forming bonds between two or more atoms of the same element or different elements. Symbolic Perspective refers to representing atoms, molecules and chemical reactions in a system using symbols.

Question

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure. 2. The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC. 4. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…

Interpretation Introduction

Interpretation:

Usefulness of microscopic, macroscopic and symbolic perspectives in understanding a chemical system should be explained.

Concept Introduction
The characteristics we can see in a system and reactions happen in the system as a whole are the macroscopic qualities.Therefore, observing characteristics of the whole system refers to the macroscopic perspective.

The characteristics of a single atom or a molecule are considered as microscopic properties. Therefore considering those microscopic properties such as speed, size, energy of individual atoms or molecules; is referred to as microscopic perspective.

A chemical system consists of atoms. Atom is the smallest unit of a system and it is unimaginably small. Sometimes atoms do not exist alone and form molecules by forming bonds between two or more atoms of the same element or different elements.

Symbolic Perspective refers to representing atoms, molecules and chemical reactions in a system using symbols.

The diagram below shows a system that is made up of 3 molecules (labeled A, B, and C) that contains a total of 4 units of energy. Assuming that no molecule can have 0 energy associated with it, and that only integral amounts of units of energy are allowed (energy = 1 or energy = 2 is allowed, but energy = 1.5 is not). In the left-most diagram, one possible way of distributing the four units of energy among these three molecules is presented. This distribution is represented as: (1, 1, 2). %3D 6 SEE 6 5 4 4 4 3 3 3 2 2 1 1 1 A B C AB C АВС (1, 1, 2) a. Show explicitly that a total of 4 units of energy are present in the left-most diagram. b. Explain why (1, 3, 0) is not an allowed distribution for this system. Show the other two allowed distributions of energy for this system using the two blank diagrams, and write the corresponding representation below each diagram. С.
