Write a lewis structure that obeys the octet rule for socl2 (s is the central atom) and assign formal charges to each atom. draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons and formal charges.

Answer :  The Lewis-dot structure of is shown below.

Explanation :

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

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is,

As we know that sulfur has '6' valence electrons, chlorine has '7' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in = 6 + 6 + 2(7) = 26

According to Lewis-dot structure, there are 8 number of bonding electrons and 18 number of non-bonding electrons.

Now we have to determine the formal charge for each atom.

Formula for formal charge :

Hence, the Lewis-dot structure of is shown below.

indium, and thallium have three electrons i think

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
