Answer:
bends and slides under one another
Explanation:
"Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle."
Answer:
SO42 - Trigonal planar ion
Explanation:
The SO4^2- ion is tetrahedral and not trigonal planar because the sulphur atom has four regions of electron density which includes the lone pair of electrons on sulphur atom.
This accounts for the observed tetrahedral arrangement of electron pairs around the central sulphur atom in SO4^2- ion, hence the answer.

Chlorine<span> is a </span>gas at room temperature.<span>The melting/boiling point of a substance determines what state of matter it takes at a certain temperature.</span>
I believe this nuclide is potassium with the symbol K. Atomic number for an element remains constant no matter how the mass changes. From the periodic table, potassium has an atomic number of 19.
D is the answer. You're welcome...
