Answer:

True

Explanation:

Valence electron:

No. of electrons present in the outermost shell of any atom is called valence electrons. Valence electrons determines the chemical properties of element.

Atomic no. of S = 16

Electronic configuration of S = 1s^22s^22p^63s^23p^4

Energy shell (n = 3) is the outermost shell

Valence electrons = 6

Atomic no. of Cl = 17

Electronic configuration of S = 1s^22s^22p^63s^23p^5

Energy shell (n = 3) is the outermost shell

Valence electrons = 7

So, sulfur has 6 valence electrons and Cl has 7 valence electrons.

The statement 'Sulfur has fewer valence electrons than chlorine.' is true.

When an excited electron spontaneously emits a photon, which energy transformation takes place
notka56 [123]

Given what we know, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy.

<h3>What is a Photon and what energy does it release when being emitted?</h3>
  • A photon is a particle.
  • This means that it is one of the smallest forms of matter that we can study.
  • Photons form electromagnetic fields.
  • Therefore, when being emitted by an electron, photons release electromagnetic energy.

Therefore, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy due to the properties of the photon being emitted.

Write the word and balanced chemical equations for the reaction between:
nadezda [96]

Answer:

3 HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃

Explanation:

An acid reacts with a base producing water and a salt. Having this in mind the reaction of nitric acid (HNO₃) and Iron (III) hydroxide (Fe(OH)₃) is:

HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃

<em>The H⁺ of the acid reacts with the OH⁻ to produce H₂O. The other ions (Fe³⁺ and NO₃⁻) produce the salt</em>

<em />

There are 3 nitrates in products. To balance the nitrates:

<h3>3 HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃</h3>

<em>And this is the balanced reaction</em>

A salt solution will conduct electricity but if sugar solution will not explain why​
Rainbow [258]

Salt solution such as sodium chloride (NaCl) conducts an electric current because it has ions in it that have the freedom to move about in solution. ... On the other hand, sugar solution does not conduct an electric current because sugar (C12H22O11) dissolves in water to produce sugar molecules
