Answer: 1. 
2. 3 moles of 
: 2 moles of 
3. 0.33 moles of : 0.92 moles of
4. is the limiting reagent and is the excess reagent.
5. Theoretical yield of 
is 29.3 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
3 moles of require = 2 moles of
Thus 0.33 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 3 moles of give = 2 moles of
Thus 0.33 moles of give = of
Theoretical yield of 
Thus 29.3 g of aluminium chloride is formed.

<h3>Monoatomic vs Polyatomic Ions</h3>
In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include , , and
Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.
Examples of polyatomic ions are , , , , , and
Thus, from the diagram:

Force = mass x acceleration
4.2kg x 1.6m/s^2 = 10.92N
Explanation:
Population is hugely dependent on the environment and it's factors. The physical, chemical and biological components of the environment plays vital roles in the sustenance of all life on earth.
A change in the environment can lead to terrifying consequences. Let's examine some of the changes:
- Climate change can lead to flooding of biological habitats and where people typically reside. This can lead to death and loss of life.
- Drought can lead to decline in food production. During a drought, a place receives little to no rainfall and the land is not fit for agricultural practices. This will eventually lead to famine.
- Pollution: it is the introduction of harmful substances into the environment. Pollution is harmful to the population.
- Geological hazards; earthquakes, volcanic eruptions,mass wasting and so on can lead to a crash in population.
- Wildfires, tornadoes, dust bowls e.t.c are changes in the environment that can cause severe consequences on the population.
