Answer:
Power = 7.5 watt
Explanation:
Given data:
Power expend = ?
Force applied = 10 N
Distance cover = 1.5 m
Time = 2 s
Solution:
Power = work/ time
First of all we will calculate work.
Work = Force × distance
Work = 10 N × 1.5 m
Work = 15 N.m
Now we will calculate the power.
Power = 15 N.m / 2s
N.m/s = 1 watt
Power = 7.5 watt
1. Find its coordination figure/coordination number of central atom (CF)
Ev = Vallence electron of central atom
Σe = electrons donated from substituents
Terminal O gives 0 electrons, hence Σe = 3 x 0
charge = charge of the compound
2. Find EP (electron pairs) and LP (lone pairs)
LP = CF - EP
3. Draw the skeleton with octet substituents (top right figure)
4. Find formal charge for each atoms (Qf)
5. Write formal charge near atom in skeleton
6. Enjoy

Explanation:
NaCl; Sodium Chloride is an ionic compound formed by sodium and Chlorine.
Ionic bond is very strong, It can't be separated back to sodium and chlorine just by physical change. Chemicals which are more reactive can displace ions, thus seperate it
