Answer:
True water is wet because when something is wet in this case it's water it has water on it at a molecular level. Water molecules are bonded on top of each other so it's wet.
Answer:
See Explanation
Explanation:
Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.
Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.
Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of solar energy.
Answer:
Electron dot structure
Explanation:
This is because electron dot structure is the structure that shows or indicate valence electrons of an atom and dots
is use around the element symbols . The number of dots shows the total number of valence electrons that are present in the atom of the molecules.
Answer:
gram
Explanation:
Gram is a SI unit (International Ststem of units)
other SI units : kg , meter, ampere, Kelvin
pound gallon and foot are SAE (or imperial) units
The hybridization for the Br in BrO4⁻ is 
. So, the correct option is (e).
In chemistry, the idea of combining atomic orbitals to create new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) is known as orbital hybridisation (or hybridization). These new hybrid orbitals are suitable for the pairing of electrons to form chemical bonds in valence bond theory.
Because more directional hybridised orbitals result in higher overlap when creating bonds, stronger bonds are formed, which favours the hybridization of orbitals. When hybridization takes place, this leads to more stable molecules.
One s orbital and three p orbitals combine to form four orbitals, each of which has a 25% s character and a 75% p character. This process is known as hybridization. Anytime an atom is surrounded by four groups of electrons, this kind of hybridization is necessary.
