Explanation :

Lewis-dot structure : Lewis-dot structure shows the bonding between the atoms of a molecule. It also shows the number of paired and unpaired electrons present in the molecule.

The given molecule is, Acetylene

As we know that carbon has '4' valence electrons and hydrogen has '1' valence electron.

Therefore, the total number of valence electrons in acetylene, $C_2H_2$ = 2(4) +2(1) = 10

According to Lewis-dot structure, there are 10 number of bonding electrons and 0 number of non-bonding electrons.

The Lewis-dot structure of acetylene is shown below.

Aleksandr [31]

Explanation:

The generated Na+ and OH-ions are immediately surrounded by molecules of water (typically 6, each). There is the development of the exothermic hydration sphere for each ion. It seems as though there is negative overall energy of dissolving solid NaOH.

Now, since this dissolution is exothermic the temperature of the mixture rises.

Which statement best describes visible light?

tekilochka [14]

Answer:

The Visible Spectrum Visible light is the light that we can see, and thus is the only light detectable by the human eye. White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers.

This reaction supports the Law of Conservation of Mass (hint: is the equation balanced?):

enyata [817]

Answer:

False

Explanation:

<em>Left:</em>

K = 2 atoms

O = 1 atoms

H = 1 atoms

<em>Right: </em>

K = 2 atoms

O = 1 atoms

H = 2 atoms

O = 1 atoms

As you can see both sides do not have the same amount of atoms, therefore it is not balanced.
