Answer:
The acceleration of the box across the floor is 7.0588 
Explanation:
Given:
Mass of the box = 2550 gram
net force acting on the box = 18 .0 N.
To Find:
The acceleration of the box across the floor = ?
Solution:
Newton's 2nd Law of Motion states that the acceleration of an object as produced by a net force is "directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
"
Newton's Second Law formula is
F = m a
Where:
F = the magnitude of the net force, in N
m = the mass of the object, in Kilogram
a = the acceleration of the object, in 
Now substituting the values, we get
18.0 = a (2.55) [since 2550 gram = 2.55 kg]

a = 7.0588 
The correct answer is Water, H2O. One oxygen and 2 hydrogen ions.
