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).
