Column B
a. Atomic Number
b. Number of Neutrons
c. Atomic Mass
d. Symbol
e. Number of Electrons
f. Charge

A- Atomic mass

Z -Atomic number.

X - Symbol.

C - Charge

Explanation:

Given that,

The elements in figure,

A, Z, X and C

The elements given in column A.

The meaning of element given in column B.

We need to find the meaning of the letters from the column B

Using column B,

A shows the atomic mass.

Z shows the atomic number.

X shows the symbol.

C shows the charge

Hence, A- Atomic mass

Z -Atomic number.

X - Symbol.

C - Charge

b.final

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
