Answer with Explanation:
Water is a<em> compound </em>because it consists of<u> two types of atoms</u> <em>(Hydrogen and Oxygen)</em> that are chemically bonded. An<em> "element"</em> only consists of one type of atom, therefore, water is not an element but a compound. Its chemical formula is: . This means that water consists of <u> 2 atoms of Hydrogen that are bonded to an atom of Oxygen.</u> Take note that a compound is <em>different compared to the elements that it is made of</em>. For example, water is essentially liquid in its form but it is different from the atoms of Hydrogen and Oxygen, which are gas in form.

Answer:
The frequency of the photon is 7.41*10¹⁶ Hz
Explanation:
Planck states that light is made up of photons, whose energy is directly proportional to the frequency of radiation, according to a constant of proportionality, h, which is called Planck's constant. This is expressed by:
E = h*v
where E is the energy, h the Planck constant (whose value is 6.63*10⁻³⁴ J.s) and v the frequency (Hz or s⁻¹).
So the frequency will be:
Being E= 4.91*10⁻¹⁷ J and replacing:
You can get:
v= 7.41*10¹⁶ = 7.41*10¹⁶ Hz
<u><em>The frequency of the photon is 7.41*10¹⁶ Hz</em></u>
