Answer:
4000m/s
Explanation:
It would be this because sound travels faster through a solid rather than a liquid.
No. We don't know of the existence of another universe besides
the one we live in, and we can't even explain THIS one.
Positive Impact
1. Going digital has allowed business to use less paper hence saving trees which is good for the environment.
2. Technology has also allowed a shift from hydrocarbon fuel cars to battery-powered cars. This saves the environment from carbon emissions.
Negative Impact
1. Technology has caused an increase in gadgets that pollute the environment when improperly disposed of. This waste can be more toxic than other traditional wastes.
2. Increased technology use has resulted in an increased energy demand. This has resulted in a strain on natural resources and have a negative impact on the environment.
It behaves more like a metal
Explanation:
When an element tends to lose its valence electrons in chemical reactions, they behave more like a metal.
Metals are electropositive.
Electropositivity or metallicity is the a measure of the tendency of atoms of an element to lose electrons.
This is closely related to ionization energy and the electronegativity of the element.
- The lower the ionization energy of an element, the more electropositive or metallic the element is .
Metals are usually large size and prefers to be in reactions where they can easily lose their valence electrons.
When most metals lose their valence electrons, they attain stability.
Non-metals are electronegative. They prefer to gain electrons.
