luminous is relating to light as it is perceived by the eye, rather than in terms of its actual energy.
A brief description explaining the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.
What is luminous ?Luminous objects are things like the sun that produce or radiate light on their own. Others include a torch, an electric lamp, etc. Non-bright objects are those that don't emit any light of their own and can only be seen when light from a luminous source reflects off of them. Moon, a chair, a painting, etc. are a few examples.
Luminous objects are defined as those that produce their own light. Just the sun emits its own light; all other things only reflect light that is incident upon them.
The presence of luminous items produces the feeling of light. These things are visible because they independently emit light. As an illustration, consider the Sun, the stars, lightbulbs, torches, tube lights, candles, and so on.
Thus,the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.

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).
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.
Explanation:
Sodium belongs to Group I and Period 3 of the Periodic Table and iodine belongs to Group VII and Period 5. Based on this information, what can you tell about the atoms of sodium and iodine?
Explanation:
Sodium is a highly reactive metal since it has 1 valence electron, while Iodine is a less reactive non metal with 7 valence electrons.

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.

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 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.

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.
