<span>Metals are good conductors of electricity because of the free electrons that is present in their outer shell that makes them good conductors of electricity. This is the most accepted fact that for any thing to transmit electricity by being a good conductor they need more free electrons in their outer shell</span>

metal   have   free electrons  in  their   outer  shell  which  make  them  generally  good  conductors  of  electricity. Example  is  the  copper  which   is  used  for  electrical  wiring   since  is  a good  conductor  of  electricity.  copper  with   electronic configuration  of  (Ar)4s2 has  two  free  electrons  in  their  outer  most shell which  allow  it  to  conduct  electricity.

A 64.4-g sample of potassium chloride was added to 200.0 g of water at 20 degrees C. Is the solution saturated, unsaturated, or
Tomtit [17]
Hey there!:

is the solution <span>saturated  , ie :

</span>They are the ones that have reached the exact solubility coefficient.<span>If we mix 64.4 g of KCl at 200.0 g of water at 20 º C, we'll see that the 32.2 g will dissolve and the remainder (32.2 g) will precipitate, forming the bottom body. In this case we will then have a solution saturated with background. However, if we want only the saturated solution, simply perform a simple filtration to separate the precipitate from the saturated solution.

hope this helps!</span>

Are solar and lunar eclipses processed by the movements of the Earth and moon?
Inga [223]

Explanation:

As the Earth rotates on its axis and revolves around the Sun, several different effects are produced. When the new moon comes between the Earth and the Sun along the ecliptic, a solar eclipse is produced. When the Earth comes between the full moon and the Sun along the ecliptic, a lunar eclipse occurs.

Draw the lewis structure of ch3nc; fill in any nonbonding electrons. Calculate the formal charge on each atom other than hydroge
jenyasd209 [6]

A visual representation of covalent bonding which represents the valence shell electrons in the molecule is said to be a Lewis structure. The lines represents the shared electron pairs and dots represents the electrons that are not involved in the bonding i.e lone pairs.

Number of valence electrons in each atom:

For Carbon, C = 4

For Hydrogen, H = 1

For Nitrogen, N = 5

The Lewis structure of CH_3NC is shown in the attached image.

The formula of calculating formula charge = FC = VE - NE- \frac{BE}{2}   -(1)

where, F.C is formal charge, V.E is number of valence electrons, N.E is number of non-bonding electrons and B.E is number of bonding electrons.

Now, calculating the formal charge:

For C on left side:

FC = 4 - 0- \frac{8}{2} = 0

For N:

FC = 5 - 0- \frac{8}{2} = +1

For C on right side:

FC = 4 - 2- \frac{6}{2} = -1

The formula charge of each atom other than hydrogen is shown in the attached image.
