Enyzmes speed up all chemical reactions
(Just took an AP Bio test with this question on it)
Answer:
-Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
-An atom has an equal number of protons and electrons. An ion has an imbalance between the number of protons and electrons.
-An atom has no electrical charge. Ions have an electrical charge because they have an imbalance of protons and electrons.

When a substance melts, the solid gains heat, and the motion of the particles increases (particles move faster in liquid form than in solid form).
If the level of acid in a lake increased, then the number of fish that live there will be decreased because highly acidic lakes will not have enough food for the fish to survive. Acidic level increases , then availability of food for fish decreases as some food will be contaminated so if the fish won't got enough food for their survival then their number of fish decreases.
This the answer for you hope it work out for you
