Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 
.
<u>Given the following data:</u>
- Mass of box = 50 kilogram
To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;
Making acceleration the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Acceleration = 0.5

Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.
The empirical formula for the citric acid is C₆H₈O₇
<h3>Data obtained from the question </h3>
Divide by their molar mass
C = 37.51 / 12 = 3.126
H = 4.2 / 1 = 4.2
O = 58.29 / 16 = 3.643
Divide by the smallest
C = 3.126 / 3.126 = 1
H = 4.2 / 3.126 = 1.34
O = 3.643 / 3.126 = 1.17
Multiply through by 6 to express in whole number
C = 1 × 6 = 6
H = 1.34 × 6 = 8
O = 1.17 × 6 = 7
Thus, the empirical formula for the citric acid is C₆H₈O₇

Answer:
Covalent bond
Explanation:
A covalent bond is formed when two atoms share electrons. The shared electrons are positioned between the nuclei of the bonding atoms.
In the bonding between chlorine and hydrogen, chlorine has seven valence electrons. Hence, it needs one more electron in order for the atom to attain an octet structure. Hydrogen has one valence electron and needs one more electron in order to attain a duplet structure.
The two bonding atoms now share two electrons(provided by each of the bonding atoms) in a covalent bond such that chlorine has a complete octet and hydrogen has a complete duplet.
