Relate microscopic bonding properties to solid state properties
There are many factors that we can take into account when attempting to relate microscopic bonding properties to solid-state properties, for example, the rigid and immobile nature of solid states and their molecular bonds.
Solid-state properties are simply put, the properties we can observe and measure when studying an element in solid form. These solids have specific characteristics such as:
Structural rigidityThey do not change shapeDo not change the volume they occupyand so on, which although not initially obvious, are caused by the microscopic molecular bonds of their atoms.
The microscopic properties of solids are very similar to that of the solid-state properties. The atoms of a solid are very close together and strongly bonded to one another, because of this the atoms form a very rigid structure that resists changes to their shape or volume, much like the macroscopic properties of the solid. This serves to show how these properties may cause the solid-state effects we can observe normally.

What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?
Answer:
2.3)X10^13-Hz
Explanation:
What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?
a micro meter is 10^-6 meter
frequency of light times wavelength = c the speed of light 3X10^8 M/sec
so
frequency times 13 X10^-6 =3X10^8 M/
so
FR3EQUENCY = 3X10^8/13X10-6
=(30/13)10^13 =2.3)X10^13-Hz

Hydrogen fusion creates _____ and lots of energy.
Explanation:
Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion energy production. Proposed fusion reactors generally use hydrogen isotopes such as deuterium and tritium (and especially a mixture of the two), which react more easily than hydrogen to allow them to reach the Lawson criterion requirements with less extreme conditions. Most designs aim to heat their fuel to around 100 million degrees, which presents a major challenge in producing a successful design.
As a source of power, nuclear fusion is expected to have many advantages over fission. These include reduced radioactivity in operation and little high-level nuclear waste, ample fuel supplies, and increased safety. However, the necessary combination of temperature, pressure, and duration has proven to be difficult to produce in a practical and economical manner. Research into fusion reactors began in the 1940s, but to date, no design has produced more fusion power output than the electrical power input.[1] A second issue that affects common reactions is managing neutrons that are released during the reaction, which over time degrade many common materials used within the reaction chamber.
Fusion researchers have investigated various confinement concepts. The early emphasis was on three main systems: z-pinch, stellarator, and magnetic mirror. The current leading designs are the tokamak and inertial confinement (ICF) by laser. Both designs are under research at very large scales, most notably the ITER tokamak in

(e) alkaline earth element with the least massive atoms
The alkaline earth element with the least massive atoms is beryllium (Be). Beryllium, located in Group 2 of the periodic table, possesses the lowest atomic number and atomic mass within the alkaline earth elements.
Among the alkaline earth elements, which are found in Group 2 of the periodic table, beryllium (Be) stands out for having the least massive atoms. The periodic table is organized in a way that elements are ordered by increasing atomic number, which corresponds to the number of protons in an atom's nucleus. For alkaline earth elements, the atomic numbers increase from beryllium (Be) with atomic number 4 to radium (Ra) with atomic number 88.
Atomic mass, on the other hand, takes into account the sum of protons and neutrons in an atom's nucleus, as electrons contribute very little to the overall mass. Since beryllium (Be) has the lowest atomic number in the alkaline earth group, it also has the fewest protons and neutrons among its isotopes, leading to a lower atomic mass compared to other elements in the same group.

Predict the product of each monosaccharide oxidation reaction.
The complete oxidation of the monosaccharide shown will create a carboxylic acid.
Monosaccharides can be oxidized to carboxylic acids. Recall that monosaccharides have an aldehyde or ketone group at one end and a CH2OH group at the other end.
For the monosaccharide shown, oxidation may lead to the conversion of COH group to acid (-COOH). This confirms the presence of -COH yielding the product C4H8O5.

A reaction mixture initially contains 0.236 mol FeS and 0.670 mol HCl. Once the reaction has reached completion, what amount (in moles) of the excess reactant is left
Answer:
= 0.198 mole H₂S in excess
Explanation:
A quick way to determine limiting reactant is to convert reactant values given to moles and divide by respective coefficient. The smaller value is the limiting reactant other reactants will be in excess. However, when working problem, use mole values given to solve, not results of division.
FeS + 2HCl => FeCl₂ + H₂S
0.236mole/1 0.670mole/2
= 0.236 = 0.335
limiting reactant is FeS; HCl will be in excess.
Problem solution
0.236mole FeS used + 2(0.236 mole HCl used)
=> 0.236 mole FeCl₂ + 0.236 mole H₂S + (0.670 - 0.472) mole HCl in excess or, 0.198 mole H₂S in excess.

Why is there an octet rule in writing Lewis structures?
Answer:
Before we can sketch the Lewis structures of molecules, we must first understand the octet rule. The octet rule asserts that when atoms combine to create compounds, electrons are gained, lost, or shared among them, resulting in a stable electron configuration defined by eight valence electrons as a result. These rules are used in conjunction with the main-group components of the second period.
