Write out the molecular formula and lewis structure for cyanide

Answer :  The molecular formula of cyanide is, and Lewis structure of cyanide 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 carbon has '4' valence electrons, nitrogen has '5' valence electrons.

Therefore, the total number of valence electrons in = 4 + 5 + 1 = 10

The skeleton structure of the compound, C molecule act as a central atom and is bonded to N with one sigma-bond and two pi-bonds with one negative charge.

Hence, the molecular formula of cyanide is, and Lewis structure of cyanide is shown below.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
