Answer:
Here, acceleration due to gravity(a) is assumed as 10m/s².We can also take it as 9.8m/s²
Explanation:
Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.
Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).
Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.
Troposphere is the highest layer of the atmosphere and touches space
Startophere is where stratus clouds form up high in the sky
The Mesosphere is the third layer you need to know and it’s low density ...yo?
Thermosphere we’re getting closer and closer to earth
Exoshpere were airplanes are high, buckle up it’s time to fly
Heat energy is absorbed by the substance.
