So the question ask to calculate the over all equation for a certain element and the following are
- over all equation - FE(OH)3+3NH4CI
- over all ionic equation - e(OH)3 (s) & 3 NH4+ (aq) & 3Cl- (aq) - net ionic equation - Fe+3+3OH-+3NH$++3CI-

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of iron(III) chloride, ammonia and water is given as:

$FeCl_3(aq.)+3NH_3(g)+3H_2O(l)\rightarrow Fe(OH)_3(s)+3NH_4Cl(aq.)$

Ionic form of the above equation follows:

$Fe^{3+}(aq.)+3Cl-(aq.)+3NH_3(g)+3H_2O(l)\rightarrow Fe(OH)_3(s)+3NH_4^+(aq.)+3Cl^-(aq.)$

As, chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and is the spectator ion.

The net ionic equation for the above reaction follows:

$Fe^{3+}(aq.)+3NH_3(g)+3H_2O(l)\rightarrow Fe(OH)_3(s)+3NH_4^+(aq.)$

Hence, the net ionic equation is written above

The Development and Characterization of Carbon Nanofiber/Polylactic Acid Filament for Additively Manufactured Piezoresistive Sen

horrorfan [7]

Compared to carbon nanotube, carbon nanofiber (CNF) is a unique quasi-one-dimensional nanostructure with a lot of edges and flaws (CNT). Additionally, their low cost and wide availability make them a valuable nanomaterial for upcoming technology.

<h3>what are the development and characterization of Carbon Nanofiber for Additively Manufactured Piezo resistive Sensors?</h3>

In accordance with the semiconductor material's piezo resistive effect, diffusion resistance is used to manufacture piezo resistive sensors on substrates of semiconductor materials. The diffusion resistor is connected in the substrate in the form of a bridge, allowing the substrate to be employed directly as a measuring sensor element.

Carbon nanofiber/polylactic acid filament for fused filament fabrication (FFF) and additive manufacturing (AM) strain sensors was studied for the effects of production factors.
To investigate the effects of CNF weight fraction, extrusion temperature, and number of extrusions on sensor performance, a design of experiments (DOE) approach was used. In the initial extrusion, dry melt mixing was used to combine CNFs and powdered PLA material.
Through the DOE procedure, it was discovered that extruding CNF/PLA material for two complete extrusions at 185 °C resulted in material with material with material with dramatically improved electrical characteristics in comparison to unmodified material.
Piezoresistive dog-bone shaped sensors were made using the best manufacturing technique using three different sizes of 5.0, 7.5, and 10.0 wt% CNF/PLA filament.

There are 48.72 g Fluorine ions

<h3>Further explanation </h3>

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

%F in CaF₂ :

$\tt \%F=\dfrac{2.Ar~F}{MW~CaF_2}\times 100\%\\\\\%F=\dfrac{2.19}{78}\times 100\5=48.72\%$

mass of Fluorine :

$\tt 48.72\%\times 200=97.44~g$

So mass Fluorine ions(2 ions F in CaF₂⇒Ca²⁺+2F⁻) :

$\tt =\dfrac{97.44}{2}=48.72~g$

Explain how different observations and experiments led to changes in the atomic model.

Bingel [31]

> Explain how different observations and experiments led to changes in the atomic model.

The atomic model has progressed over time. As scientists have learned more about the atoms, the atomic model has changed.

Democritus: first proposed that matter cannot be divided into smaller pieces

Dalton: created the 1st atomic theory. He viewed atoms as tiny solid balls

JJ Thomson: discovered electrons, he showed that atoms are made of even smaller things

Rutherford: discovered protons and nucleus, he showed that atoms have positive particles in the center and that atoms are made up mostly of empty space

Bohr: improved Rutherford’s model by proposing that electrons move around the nucleus in layers or shells

Chadwick: discovered neutrons = particles with no charge

The modern model of the atom is made up of works collaborated since 1920 which has electrons moving around the nucleus in a cloud.

> Explain how line spectra are used to identify elements and what they indicate about atoms.

Actually each element has its own unique spectra, hence this property can be used to identify the element. The line spectra give us an indication about the energy levels of the electrons, and each wavelength produces different colors.

> Represent electron arrangements using electron configuration, orbital notation, shorthand notation, and Lewis dot notation.

To answer your question, I will illustrate an example. The s orbital can accommodate 2 electrons, p orbital can accommodate 6, d orbital can accommodate 10, f orbital can accommodate 14. To take as example, Mg contains 12 electrons using the Aufbau principle, the electron configuration is: 1s2 2s2 2p6 3s2 the numbers after the letter represent the amount of electrons, the letters (s, p) represent the sublevel of the electron, while the number before the letter represent the principal quantum number, or "level".

Apply the rules and limitations of each quantum number to identify possible and impossible quantum number sets.

>There are four quantum numbers.

1. Principal quantum number (n) can take values of any positive whole numbers

2. Angular momentum quantum number (l) is from 0 to n – 1

3. Magnetic quantum number (ml) is from –l to +l

4. Spin quantum number (ms) only takes two values, positive spin and negative spin: +1/2, -1/2

From these rules you can identify possible and impossible set of quantum numbers.
