Answer:
Both Magnesium and aluminium rods are metals, hence they allow flow of charged electrons due to high drift velocity.
Explanation:
• An electric conductor is material which allows flow of electric current.
[tex].[/tex]
The Magnesium (Z = 12) is an alkaline earth metal and the Aluminium (Z = 13) is a metal in the Boron Group. One characteristic of the metals is that they have facility to lose electrons, wich means facility to conduct electricity.
Moreover, the metals are ductile, so it is easy to turn them into wires. For example, the light poles has wires made by copper because the copper is another metal, so its have the same properties as indicated above.

why is water able to easily dissolve ionic compounds?
Answer:
To dissolve an ionic compound
Explanation:
the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. Water is a polar molecule. ... When you place an ionic substance in water, the water molecules attract the positive and negative ions from the crystal.

What does a flat, horizontal line mean on a
DISTANCE-time graph?
Speeding up
Travelling at a constant speed
Not moving (motionless, stationary)
Answer:
Explanation:
A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!

How can you destroy the world by controlling
matter or atoms?
Answer:
Make them all gather up at the core of the Earth so it will attract everything towards it and practically just condense the planet.
But why are you even planning to do that? :/
How do gas laws predict absolute zero?
Answer:
If a gas contracts by 1/273 of its volume for each degree of cooling, it should contract to zero volume at a temperature of –273°C; this is the lowest possible temperature in the universe, known as absolute zero.It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.
Explain why rubidium is less reactive than caesium.
Answer:
Like other alkali metals, rubidium metal reacts violently with water. As with potassium (which is slightly less reactive) and caesium (which is slightly more reactive), this reaction is usually vigorous enough to ignite the hydrogen gas it produces.

what phenomenon is the basis behind the ability to separate miscible liquids by distillation?
Answer:
The basis of the separation by steam distillation is that while the water and organic condensed phases are immiscible, the vapors of both are miscible. Once condensed, the two separate again allowing for an easy separation. As noted above, both liquids and solids can be distilled by steam.

in order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move
In order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move different components of a mixture at different rates.
Chromatography involves the separation of substances using the application of the solubility differences in them. It has two phases known as the stationary and mobile phases.
The mobile phase involves motion which is why the ability of substances to move at different rates is a great factor in this type of phase. The Stationary phase on the other hand doesn't involve movement of substances.

why all carbon containing atoms are not organic?
Answer:
Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen. The atoms of an organic molecule are typically organized around chains of carbon atoms. Inorganic compounds make up 1%–1.5% of a living cell's mass.
Answer:
They are made up of only one type of element, which is carbon, and therefore would fail to be categorized as an organic compound since they are not, in the first place,a compound, but a pure element.
What happens when the light enters the water and then when it leaves the water?
Answer:
As light initially enters the water, it is refracted as in figure (b) and then reflected off the mirror (at the bottom of the glass). Upon exiting the water, the light is bent away from the normal as it passes from water (more dense) and into air (less dense).
