3. Product

4. C. Balanced

5. B. Atoms of the same kind are of equal number on either side of the arrow

Step-by-step explanation:

A chemical bond is a bond between two or more atoms. There are different types of chemical bonds, but the one that the question is pertaining to is called a covalen bond. A covalent bond occurs when the atoms are sharing electrons.

2. A chemical reaction is characterized by the production of light and/or heat, and a change in color in the product. By definition, it is the process where one or more substances react to produce one or more products.

3. When one or more reactants react with each other, it creates another substance or substances called products. In the case of your question, sodium reacts with chlorine (these are your reactants), which produces the product sodium chloride, which is a compound.

4. By definition, a balanced equation is an equation where the number of atoms of each element in the reactants are equal to the number of atoms of each element in the product.

ex.

Reactants Product

Na + Cl → NaCl

Na = 1 Na = 1

Cl = 1 Cl = 1

5. As explained above and shown, you can see that the number of atoms of each element in the reactants is equal to the number of each element in the product. So this means that the equation is balanced.
