Answer:
The answer is 17.03052. We assume you are converting between grams Ammonia and mole.
(a) f = 5.00 × 10²⁰ Hz, E = 3.32 × 10⁻¹³ J;
(b) f = 1.20 × 10¹⁰ Hz, E = 7.96 × 10⁻²⁴J.
<h3>Explanation</h3>
What's the similarity between a gamma ray and a microwave?
Both gamma rays and microwave rays are electromagnetic radiations. Both travel at the speed of light at 
in vacuum.
where
- f is the frequency of the electromagnetic radiation,
- c is the speed of light, and
is the wavelength of the radiation.
(a)

Answer : Option D) Silicates.
Explanation : The minerals with the silicon-oxygen structures are classified as silicates.
As per the definition, A silicate is any member of a family which has anions consisting of silicon and oxygen, usually they have the general formula as [SiO].
It usually has a structure which has a central silicon ion which has a charge of (+4) while each oxygen has a charge of negative two (-2) and thus each silicon-oxygen bond is equal to one half (1/2) of the total bond energy of oxygen. Therefore, it confirms that the answer is Silicates.
Liquids flow and take the shape of their containers.
