Answer:
This is not accurate we dont know what your asking us?
Explanation:
The answer is C. Measure from crest to crest.
Answer:
Check Explanation
Explanation:
In this case the Mushroom would get energy from decomposing dead plants and animals in the soil/ground
The plant would get energy from the sun (simplified)
the rabbit would get energy from eating the plant
in this case the wolf would energy from eating the rabbit but in a normal setting the wolf could get energy from eating any animal
CO₂ has 4 + 2(6) = 16 valence electrons
CO₂ have linear molecular structures with a 180° bond angle. CO₂ is nonpolar because the individual bond dipoles cancel each other out
XeCl₂ has 8 + 2(7) = 22 valence electrons.
There are five pairs of electrons about the central Xe atom. The structure will be based on a trigonal bipyramid geometry. The most stable arrangement of the atoms in XeCl₂ is a linear molecular structure with a 180° bond angle. It is nonpolar because the Xe−Cl bond dipoles and lone pairs around Xe are arranged in such a manner that they cancel each other out.
(b)
SCl₆ is nonpolar because it has 6 bonding pairs and no lone pairs, giving it an octahedral shape. When you draw the vectors, you can see that the resultant is 0, making it nonpolar.
SCl₄ on the other hand is polar because it has 4 bonding pairs and one lone pair, giving it a trigonal pyramidal shape.
SCl₂ is also polar due to reasons similar to those in the case of SCl₄.
