The formula for aluminium chloride will be correctly written as AlCl3.
Aluminium is a metal and in this reaction it is an electron donor. It has three electrons in its outermost shell and it is ready to give out all the three electrons to chlorine. Chlorine is a non metal and is an electron acceptor and it is more than ready to accept electrons from aluminium. But a chlorine atom can only receive only one electron from aluminium because, it already has seven electrons in its outermost shell and it only needs eight electrons in its outermost shell to be stable. To solve this problem, three chlorine atoms will react with one aluminium atom in order to accept all the three electrons from aluminium, hence the chemical formula AlCl3..

There simple rules for series and parallel circuits.
For the series circuits we have the following rules:
1)The same current flows through each part of a series circuit.(<span>I = I1 = I2 = I3)
2)</span>The total resistance of a series circuit is equal to the sum of individual resistances.(<span>Req = R1 + R2 + R3)
3)The</span> voltage applied to a series circuit is equal to the sum of the individual voltage drops.(<span>V = V1 + V2 + V3)
</span>For the parallel circuits we have the following rules:
1)Voltage is the same across each component of the parallel circuit.(<span>: V = V1 = V2 = V3)
</span>2)The sum of the currents through each path is equal to the total current that flows from the source.(<span> I = I1 + I2 + I3)
3)The total resistance is equal to the sum of the reciprocal value of individual resistors in the circuit.
The x region represents the series circuit. The y region represents a combination of series and parallel circuit. This means that for y region we can apply laws for both series and parallel circuits.
So, all the equation can be applied to the y region.
However, not all equation can be applied to the x region. We can apply following equation to the x region:
1)</span><span>I = I1 = I2 = I3
</span>2)<span> V = V1 + V2 + V3
3)</span><span>Req = R1 + R2 + R3</span>
The region of the atmosphere where the radio waves are scattered is the thermosphere .
<h3>What are radio waves?</h3>
Radio waves are part of the electromagnetic spectrum. They are the waves that are able to travel a long distance because they have a very long wavelength and as a consequence they do have a low energy of the radiation.
Now we know that the atmosphere is composed of different spheres and the sphere that are in the atmosphere are classified based on the composition of each of these layers of the atmosphere.
The area of the atmosphere where there would be the scattering of the radio waves is in the region where it knocks off ions from the molecules of air. This area that we are referring to is the part that we call the thermosphere and ions are found there.

We determine the rate of a reaction from the given rate law by substituting the given concentrations and the order of the substances. We calculate as follows:
<span>rate = k[A]^m[B]^n
</span><span>rate = (1 x 10^-2) [2]^2 [3]^1
rate = 0.12 M /s
The rate law of a reaction is an expression that is related to the reaction rate. The parameters used are the concentration or the pressure of the reactants in the reaction. An example would be:
</span><span>
A = B + C
The rate law would be:
Rate = k[A] where k is the reaction rate constant and determined by doing experiments</span>
