The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. ... Such sound waves form the basis of intervals in music.

The higher the frequency of a sound wave (shorter distance between waves), the higher the pitch of the sound. The lower the frequency (longer distance between waves), the lower the pitch of the sound.

Answer:

2Mg + O₂ → 2MgO

Explanation:

Given reaction is:

Mg + O₂ → MgO

On the right side, we have:

1 Mg, 1 O

On the left side, we have:

1 Mg, 2 O

Add 2 as a coefficient with Mg on the right side of rxn. (Will make it 2 Mg, 2 O)
Now, Add 2 as a coefficient with MgO of the left side of rxn. (Will make it 2 Mg, 2 O)

Hence, the reaction is balanced now!

Final and balanced reaction is:

2Mg + O₂ → 2MgO
