When two atoms form a covalent bond, they share electrons from all of their orbitals. All of their orbitals, in turn, combine to
erma4kov [3.2K]

Answer:

It's false.

Explanation:

Molecular orbital theory states that the number of molecular orbitals is equal to the number of atomic orbitals that overlap. The lowest energy molecular orbital is formed when two atomic orbitals that are in phase overlap, forming a bonding molecular orbital. However, another molecular orbital is also formed, called an anti-binding orbital.

So if an "n" quantity of atomic orbitals is combined, an "n" quantity of molecular orbitals is formed.

Have a nice day!

Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
tekilochka [14]

Answer: The frequency of this light is 6.74\times 10^{17}Hz.

Explanation:-

To calculate the frequency of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light  =430nm=430\times 10^{-9}m      1nm=10^{-9}m

c = speed of light = 2.9\times 10^8m/s

\nu = frequency of light = ?

\nu=\frac{c}{\lambda}

\nu=\frac{2.9\times 10^8m/s}{430\times 10^{-9}m}

\nu=\frac{2.9\times 10^8m/s}{430\times 10^{-9}m}=6.74\times 10^{17}s^{-1}=6.74\times 10^{17}Hz

The frequency of this light is 6.74\times 10^{17}Hz.
