S (reactant)= 1
Fe (product)= 1
O (product)= 4

The answer is quite simple, look at each element and see if there is an attached number at the end. O4= 4 oxygen atoms O3= 3 oxygen atoms. You see the pattern?
Also if there is no such number attached to the element, assume there is one atom.
S(reactant) :- 1
Fe(reactant) :- 1
O(reactant) :- 4

What does this mean? Write a response in complete sentences. plz someone help!!!!!!!
Answers
Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.
