Chemical Reactions and Missing Components

What components are missing in the following chemical reactions?

1. 2Na + Cl2 → ?

2. 2MgO → ?

Answer:

1. 2Na + Cl2 → 2NaCl

2. 2MgO → 2Mg + O2

In the given chemical reactions, the missing components are filled as follows:

1. 2Na + Cl2 → 2NaCl

This reaction involves the combination of 2 atoms of sodium (Na) and 1 molecule of chlorine (Cl2) to produce 2 molecules of sodium chloride (NaCl).

2. 2MgO → 2Mg + O2

Here, 2 molecules of magnesium oxide (MgO) decompose to yield 2 atoms of magnesium (Mg) and 1 molecule of oxygen gas (O2).
