Question

When magnesium (Mg) metal reacts with oxygen (O) gas magnesium

oxide is produced. What is the balanced equation for this reaction?
2 Mg + 20 - 2MgO
Mg + 0 MgO
2 Mg + O2 → 2MgO
2 Mg + 20 - 4Mg0

Answer 1

2 Mg + O2 → 2 MgO

Step-by-step explanation:

Mg + O2 → MgO

Mg=1 Mg=1

O = 2 O = 1

Mg + O2 → 2MgO

Mg=1 Mg=1 *2=2

O = 2 O = 1*2=2

2Mg + O2 → 2MgO

Mg=1*2=2 Mg=2

O = 2 O =2
