Answer:
1) Coal is a natural resource, so is wood, wind energy, soil, salt, fluorite, water, and copper
2) Solar energy, natural gas, and wind energy are all renewable
3) Salt is non - renewable as is synthetic diamonds and plastic
4) I think it would be number
5) Based on their mineral, chemical, and textural composition
Explanation:
Hope this helps :)
Eight electrons surrounding each non-hydrogen atom is the optimal electronic arrangement for covalent molecules because it is needed to achieve an octet structure and is necessary to fill both the s and p subshells of electrons.
<h3>What is Covalent bonding?</h3>
This is the type of bonding which involves the sharing of electrons between atoms of an element.
This is done to achieve an octet configuration thereby making them stable and less reactive thereby making it the most appropriate choice.

Explanation:
Given that,
Wavelength = 6.0 nm
de Broglie wavelength = 6.0 nm
(a). We need to calculate the energy of photon
Using formula of energy
(b). We need to calculate the kinetic energy of an electron
Using formula of kinetic energy
Put the value into the formula
(c). We need to calculate the energy of photon
Using formula of energy
(d). We need to calculate the kinetic energy of an electron
Using formula of kinetic energy
Put the value into the formula
Hence, This is the required solution.
Answer:
25N
Explanation:
100 - 75 = 25
That should be right if im not dumb...
