How does the atomic arrangement of atoms lead to its crystal structure like was seen in the sample of bronze and gold and Timber

Margaret [11]

In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. Atomic arrangement of atoms in this kind of structure usually very symmetrical and highly ordered. Causing the component within the structure is so strong and hard to break. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice. Crystal structure would be commonly found in solid compounds.

Answer:

It is an example of coupling an exogenic reaction to an endogenic reaction.

Explanation:

The endergonic reaction is typically being pushed by coupling it to strongly exergonic reaction. This is in most cases via shared intermediates. Most chemical reactions are endergonic in nature. In other word, the are not spontaneous (i.e ΔG>0). Energy must also be applied externally to initiate the reactions. The reactions can also be coupled to exergonic reactions (with ΔG<0) to initiate them through a process known as share intermediate. Because Gibbs Energy can be summed up (i.e is a state function), the combined ΔG of the coupled reaction will be thermodynamically favorable. The decomposition of calcium carbonate is a typical example.

4. Consider the following statement made in Chapter 4 of the text: "... consider that if the

AveGali [126]

The claim: "If the nucleus were the size of a grape, the electrons would be one mile away on average" is reasonably accurate because the ratios between the nucleus's sizes and the distances (between electrons and nucleus) for the two given examples are in the same order of magnitude.

To know if the claim is accurate we need to calculate the ratio of the size of the nucleus (the same as a grape) and the distance between the electrons and the nucleus for example 1 (r₁):

$r_{1} = \frac{s_{1}}{d_{1}}$ (1)

and to compare it with the ratio of the size and the distance given in example 2 (r₂):

$r_{2} = \frac{s_{2}}{d_{2}}$ (2)

Where:

s₁: is the size of the nucleus (like the size of a grape)

d₁: is the distance between electrons and nucleus of example 1 = 1 mile

s₂: is the average diameter of the nucleus = 10⁻¹³ cm

d₂: is the average distance between electrons and nucleus of example 2 = 10⁻⁸ cm

Assuming that the diameter of a grape is 3 cm (in a spherical way), the ratio of the first example is (eq 1):

$r_{1} = \frac{3 cm}{1 mi*\frac{160934 cm}{1 mi}} = 1.86 \cdot 10^{-5}$

Now, the ratio of the second example is (eq 2):

$r_{2} = \frac{10^{-13} cm}{10^{-8} cm} = 1.00 \cdot 10^{-5}$

Since r₁ and r₂ are in the same order of magnitude (10⁻⁵), we can conclude that the given claim is reasonably accurate.
