<span>London forces also known as "induced-dipole-induced-dipole interactions" and are in principle found in every molecule. The interaction occurs from the transient dipoles all molecules have as a result of fluctuations in the instantaneous positions of electrons.
</span><span>Dipole-dipole arises when we are able to set up a polarity in the molecule. So for an example if a highly electro-negative atom is bond to a less electro-negative atom then there will be a polarity in the molecule and we therefore have the dipole-dipole interaction.
</span><span>For the determination of geometry for the specific examples , use the VSEPR (Valence Shell Electron Pair Repulsion) model and by that determine the geometry.</span>
Area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus, or office building.
The advantages of local area network are:
• you can share resources
•you can share your software applications
• you can have easy and cheap communication
• you have centralized data
• you have data security
•you have Internet sharing
The disadvantages is a local area network are:
• high set up cost
• local area network administrators can see and check personal data files of each and every user
• Data security threats
• maintenance jobs
• covers limited areas
The right answer is N2(g) + 3H2(g) => 2NH3(g).
Ammonia (NH3) is produced by the synthesis of nitrogen (N2) and hydrogen (H2):
N2 + 3 H2 → 2 NH3
During the first half of the 20th century, the NH3-green was produced without CO2 emission at
from hydroelectricity, water, and atmospheric air.
H2 came from the electrolysis of water, the N2 of atmospheric air.
Answer:1962kJ
Explanation:
m=2000 kg
h=100m
G=9.81m/s²
GPE=m*G*h
GPE=2000kg*100m*9.81m/s²=1,962,000J=1962 kJ
N= m/v n=0.077/.200 = 0.385
