Step 1:
Add valence electrons of each element present in molecule,

N = 5

Br = 7

Br = 7

Br = 7
___________
Total 26

Step 2:
Draw Nitrogen in center surrounded by Br atoms and connect them with single bond and subtract 2 electrons/bond from total electrons. As there are three single bonds formed so subtract 6 electrons from total valence electrons.

26
- 6
_______
20

Step 3:
Now start adding these remaining 20 electrons in pair starting from most electronegative element. So, 18 electrons are added to Br atoms and 2 electrons are added to N atom. Now, all the atoms present in the structure have there octet complete.

What are the three hypotheses that were proposed to explain the seismic activity of Pinatubo? What process generates sulfur diox

ASHA 777 [7]

Answer:

Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.

The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-

The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.

The eruption led to the releasing of a large number of volcanic gases into the atmosphere.

The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.

A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface
