Balancing Chemical Equations

The video tutorial demonstrates how to balance the chemical equation FeS2 + Cl2. It begins by counting the atoms on both sides of the equation and identifying the imbalance. The instructor then adjusts coefficients to balance iron, sulfur, and chlorine atoms, ensuring the equation is balanced. The process involves updating atom counts and making necessary adjustments to achieve a balanced chemical equation.

What is the initial count of chlorine atoms on the product side before balancing?

• Two

• Six

• Three

• Five

What coefficient is placed in front of FeCl3 to balance the chlorine atoms initially?

• 1

• 2

• 3

• 4

How many iron atoms are there after updating the coefficient for Fe?

• One

• Two

• Three

• Four

What is the coefficient placed in front of S2Cl2 to balance sulfur atoms?

• 1

• 4

• 2

• 3

How many total chlorine atoms are there after balancing sulfur?

• Nine

• Eight

• Eleven

• Ten

What coefficient is used in front of Cl2 to finally balance the chlorine atoms?

• 5

• 6

• 3

• 4

What is the final balanced equation for FeS2 + Cl2?

• FeS2 + 2Cl2 -> FeCl3 + S2Cl2

• 2FeS2 + 5Cl2 -> 2FeCl3 + 2S2Cl2

• FeS2 + 3Cl2 -> FeCl3 + S2Cl2

• 2FeS2 + 4Cl2 -> 2FeCl3 + 2S2Cl2
