Answer:
The work done depends upon the <u> Force</u> applied and <u>Displacement</u> produced.
Explanation:
Definition: Work is said to be on a body only if a force acting on it causes a displacement in its direction
.
In other words we can say it is the product of force and displacement
Formula:
Unit:
The unit of work is Joule.
So, work depends on the force applied and the displacement caused by the applied force.
If force is applied and there is no displacement, then work is 0
.
Example: Pushing a wall does no work.
Work is positive if force applied and displacement is in same direction.
Work is negative if force applied and displacement is in opposite direction.
Answer:
180º
Explanation:
Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2
Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 , S = C = S
This is false because it doesn't matter about the mass
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, 
= 4
For Hydrogen, 
= 1
For Nitrogen, 
= 5
The Lewis structure of 
is shown in the attached image.
The formula of calculating formula charge = 
-(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 on left side:
For :
For on right side:
The formula charge of each atom other than hydrogen is shown in the attached image.
