D) warm and wet.
Water can be a catalyst, and heat speeds up reactions.
Answer: C. The number of collisions of gas particles decreases
Explanation: As temperature decreases so does everything else same with increase.

enplanation: when energy release at the focus, seismic waves travel outward from that point in all directions.
Covalent bond a chemical bond formed by two electrons that are shared between two atoms
ionic bond<span> a chemical bond formed by the electrostatic attraction between ions</span>
metallic bond<span> a bond characteristic of metals in which mobile valence electrons are shared among positive nuclei in the metallic crystal</span>
This is a combination reaction because two molecules becomes one
A + B ---> AB
