Answer:
a. Convergent boundary
b. Transform boundary
c. Divergent boundary
Explanation:
Convergent boundary are boundary where tectonic plates collide with each other. This kind of boundary might involve a collision between continental and oceanic plates, continental and continental plates and oceanic and oceanic plates. Generally, convergent boundary are regions for mountainous structures . Example of mountain formed through convergence are mountain Everest and Himalayas .
Transform boundary are boundary where tectonic plates move past each other . This kind of boundary is responsible for the creation of Extensive Fault like the San Andrea Fault.
Divergent boundary are boundary where tectonic plates move away from each other. The diverging movements brings about oceanic ridges. The mid oceanic ridges is where magma rises to the surface to form a new crust. The up welling of this magma causes further separation of this plates.
The picture above illustrate convergent, divergent and transform boundary.
Answer:
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
Explanation:
Anion:
Anion are formed when an atom gain the electrons.
Representation:
The anion of an atom is showed by adding the number of electrons gained by atom with negative sign as superscript on the symbol of an atom.
Cation:
Cation is formed when an atom lose the electron.
Representation:
The cation of an atom is showed by adding the number of electrons lose by an atom with positive sign as superscript on the symbol of an atom.
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
The common ion effect is the decreased solubility of the ionic precipitate in the solution. To promote the precipitation of the calcium sulfate, magnesium sulfate must be added.
<h3>What is the common ion effect?</h3>
It is a phenomenon that is due to the addition of the common ion already present in the solution that affects the equilibrium and is used to decrease the solubility of the solute present in the solution to increase the precipitation rate.
Magnesium sulfate will be added to the solution as it already contains the sulfate ion in the form of calcium sulfate. This will increase the precipitation of the compound as the common ion added will decrease the solubility.
Therefore, magnesium sulfate will be added to promote precipitation.

Answer:
<em>Since the 3s if now full we'll move to the 3p where we'll place the remaining five electrons. Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.</em>
