Balancing Sodium and Sulfur Reactions

The video tutorial demonstrates how to balance a chemical equation involving sodium and octa-sulfur. It begins by counting the atoms on each side of the equation, focusing first on balancing the sulfur atoms by adding a coefficient. Once the sulfur atoms are balanced, the tutorial proceeds to balance the sodium atoms, resulting in a complete and balanced chemical equation. The video concludes with a summary of the balanced equation.

What is the initial number of sulfur atoms on the reactant side of the equation?

• One

• Two

• Eight

• Sixteen

Why is it suggested to leave sodium balancing for last?

• Sodium has a higher atomic mass.

• Sodium is more reactive.

• Sodium is present in a compound.

• Sodium is by itself, making it easier to balance later.

What coefficient is added in front of Na2S to balance the sulfur atoms?

• 8

• 6

• 4

• 2

After balancing sulfur, how many sodium atoms are on the product side?

• 16

• 12

• 20

• 8

What coefficient is used in front of Na to balance the sodium atoms?

• 12

• 14

• 16

• 8
